OpenCL 2.0 provisional spec gets outlined, OpenGL 4.4 released
SIGGRAPH has only just begun, but the Khronos Group is already giving folks of the graphics programming persuasion some fresh APIs to talk about. Yesterday marked the release of the OpenCL 2.0 provisional specification, and it's boasting an Android installable client driver extension, along with improvements to image handling, shared virtual memory and more. It's expected that the new version of OpenCL will be finalized in six month's time, and feedback regarding the changes are being welcomed. The fresh OpenGL 4.4 spec revamps everything from shaders to asynchronous queries while keeping full backwards compatibility, and includes additional functions to make porting Direct3D apps a smoother process. If parallel programming and cross-platform graphics are your thing, hit the break for the full feature breakdown in the press releases.
Intel details 4th-gen Core's HD 5000, Iris and Iris Pro graphics: up to 3X faster, 3-display collage mode
Many already believe that the real highlight of Intel's 4th-generation Core processor lineup would be a giant graphics update. Today, Intel is revealing that they're right -- and, importantly, that there's an equally large shift in naming strategy. Where 3rd-generation Core graphics were divided into two tiers, the new generation is focused on three, two of which are built for performance over efficiency. Ultrabooks with 15W U-series processors will use comparatively ordinary (if still faster) HD 5000 graphics. Thin-and-light laptops with 28W U-series chips get a new tier, Iris, that Intel claims is up to twice as fast in 3D as last year's HD Graphics. Power-hungry parts see even more of a boost: they can carry Iris Pro graphics with embedded DRAM, which should double the 3D speed on H-series mobile chips (47-55W of typical power) and triple it for the R-series (around 65-84W) on the desktop. We also know that M-series laptop and K-series desktop CPUs will have Iris Pro options. The feature set for the graphics trio is slightly more familiar to us, although there are a few tricks up Intel's sleeve. All three can draw DirectX 11.1 and OpenGL 4 visuals, as well as take on OpenCL 1.2 computing and faster media processing. We're almost more interested in the display modes, though. Along with receiving "enhanced" 4K output, the new Core graphics can handle a 3-screen collage mode -- we won't need dedicated video for a large, multi-monitor canvas. Sadly, Intel isn't providing more than incidental details about the processors themselves, although it has already teased that we'll get the full story around the Computex show in early June. %Gallery-187340%
Adobe Premiere Pro on Windows to boast OpenCL support
Premiere Pro has already been tearing through video with OpenCL on Macs for a year, and now AMD and Adobe have teamed up to bring support for the open standard to Windows with the software's next version. Not only does the duo claim it's the first time Microsoft's OS has been graced with hardware-accelerated video editing using OpenCL, but they boast that exporting video replete with effects from a source to a final format can now be done up to 4.3 times faster. There's no word on when the fresh release of Premiere Pro will arrive, but if it's any consolation, Adobe says it's set to unveil some "incredible enhancements" to its video editing tools at NAB next week.
The Daily Roundup for 01.04.2013
You might say the day is never really done in consumer technology news. Your workday, however, hopefully draws to a close at some point. This is the Daily Roundup on Engadget, a quick peek back at the top headlines for the past 24 hours -- all handpicked by the editors here at the site. Click on through the break, and enjoy.
OpenCL mod for the Kindle Fire HD reveals untapped graphics potential (hands-on video)
As neat as the Kindle Fire HD already is, just a few dinky tweaks could turn it into so much more -- a platform for true physics-based gaming, for example, or even for surprisingly fast photo manipulation. How come? Because both the 8.9-inch and 7-inch versions of the Android-based slate come with a graphics engine that can handle OpenCL acceleration. It certainly won't work out of the box, but Amazon has been working quietly with Imagination Technologies -- the folks behind the tablet's PowerVR GPU -- to try it out. The demo after the break is subtle, perhaps, but it's fluid, detailed and goes far beyond anything that a stock device can achieve. It also proves that, in certain circumstances, OpenCL has the power to boost frame rates by 50 percent while simultaneously lowering power consumption by the same proportion. Read on for more.
Adobe Premiere Pro CS6 now fully supports Retina MacBook Pro: both HiDPI and GPU compute
Adobe's video editing application is already a lovely thing on the Retina MacBook Pro, but not visually -- only in terms of its raw performance on that Core i7 CPU. Until today's update -- 6.0.2 -- the software hasn't actually been able to make use of HiDPI itself, and neither has it been able to exploit the performance-boosting potential of GPU compute on the laptop's NVIDIA GTX 650M graphics card. If you're lucky enough to own this combo of hardware and software, Adobe's official blog suggests that you go ahead and check for the update or apply it manually following the instructions at the source link below (it's actually within Bridge that you should check for the update, with other Adobe titles closed). We're hopefully about to apply it ourselves and will report back on its impact. Update on the update: As expected, video thumbnails look sumptuous in the absence of pixelation, making this a worthy revision. That said, software encoding of a short timeline was still faster with the Mercury Engine set to software mode rather than GPU compute. A 2:30 clip took 2:02 to encode with OpenCL, 2:00 to encode with CUDA, but just 1:42 to encode in Software mode. No doubt people who do multi-cam editing or need to render complex effects in real-time may see a benefit -- please, let us know if you do! Update: Just had word from NVIDIA that may explain what's happening with our encoding times. We're told it's only if we enable "Maximum Render Quality" that GPU compute will shine through in terms of performance, because enabling max quality in software mode would slow it down. So far we've only tried with default settings, so clearly there's room here for more experimentation.
Engadget Primed: The crazy science of GPU compute
Primed goes in-depth on the technobabble you hear on Engadget every day -- we dig deep into each topic's history and how it benefits our lives. You can follow the series here. Looking to suggest a piece of technology for us to break down? Drop us a line at primed *at* engadget *dawt* com. As you're hopefully aware, this is a gadget blog. As a result, we're innately biased towards stuff that's new and preferably fandangled. More cores, more pixels, more lenses; just give it here and make us happy. The risk of this type of technological greed is that we don't make full use of what we already have, and nothing illustrates that better than the Graphics Processing Unit. Whether it sits in our desktops, laptops, tablets or phones, the GPU is cruelly limited by its history -- its long-established reputation as a dumb, muscular component that takes instructions from the main processor and translates them into pixels for us to gawp at. But what if the GPUs in our devices had some buried genius -- abilities that, if only we could tap into them, would yield hyper-realistic experiences and better all-round performance from affordable hardware? Well, the thing is, this hidden potential actually exists. We've been covering it since at least 2008 and, even though it still hasn't generated enough fuss to become truly famous, the semiconductor industry is making more noise about it now than ever before. So please, join us after the break as we endeavor to explain why the trend known as "GPU compute," aka "general purpose GPU (GPGPU)," or simply "not patronizing your graphics processor," is still exciting despite having let us down in the past. We'll try to show why it's worth learning a few related concepts and terms to help provide a glossary for future coverage; and why, on the whole, your graphics chip is less Hasselhoff and more Hoffman than you may have imagined.
ARM's Mali-T604 makes official debut, we get a first look at the next-gen GPU (hands-on video) (update: it's the Exynos 5)
Think those are some pretty slick graphics in your Galaxy S III? Samsung's latest smartphone packs some mighty graphics prowess of its own, thanks to the Mali-400 MP GPU, but once you spend a few minutes with the Mali-T604, the company's next-generation chipset, the improvements become quite clear. After seeing the Mali-T604 in action, as we did at SIGGRAPH today, the capabilities leave us hopeful for the future, and perhaps feeling a bit self-conscious about the silicon currently in our pockets. The reference device on hand was operating in sync with a variety of unnamed hardware, protected from view in a relatively large sealed box. We weren't able to squeeze many details out of ARM reps, who remained mum about the demo components, including clock speed, manufacturer and even fabrication size. What we do know is that we were looking at a quad-core Mali-T604 and dual-core ARM Cortex-A15 processor, with a fabrication size in the range of "28 to 40 nanometers" (confirming the exact size would reveal the manufacturer). Clock speed is also TBD, and the early silicon on demo at the show wasn't operating anywhere close to its top end. In order to experience the T604, we took a look at three demos, including Timbuktu 2, which demonstrates elements like self shadowing and depth of field with OpenGL ES 3.0, Hauntheim, which gives us an early look at physics simulation and HDR lighting with OpenCL, and Enlighten, which rendered silky smooth real-time illumination. You can see all of the demos in action after the break, and you can expect T604-equipped devices to make their debut beginning later this year -- ARM says its working with eight manufacturers to get the licensed tech to market as early as Q3. Update: ARM has just confirmed to us that this reference device is running off an Exynos 5 Dual chip (up to 1.7GHz), which means the following video is also a heads-up on what Sammy has in store for us in its forthcoming devices.%Gallery-161934%
ARM claims new GPU has desktop-class brains, requests OpenCL certificate to prove it
It's been a while since ARM announced its next generation of Mali GPUs, the T604 and T658, but in the semiconductor business silence should never be confused with inactivity. Behind the scenes, the chip designers have been working with Khronos -- that great keeper of open standards -- to ensure the new graphics processors are fully compliant with OpenCL and are therefore able to use their silicon for general compute tasks (AR, photo manipulation, video rendering etc.) as well as for producing pretty visuals. Importantly, ARM isn't settling for the Embedded Profile version of OpenCL that has been "relaxed" for mobile devices, but is instead aiming for the same Full Profile OpenCL 1.1 found in compliant laptop and desktop GPUs. A tall order for a low-power processor, perhaps, but we have a strong feeling that Khronos's certification is just a formality at this point, and that today's news is a harbinger of real, commercial T6xx-powered devices coming before the end of the year. Even the souped-up Mali 400 in the European Galaxy S III can only reign for so long.
AMD reveals Trinity specs, claims to beat Intel on price, multimedia, gaming
Itching for the details of AMD's latest Accelerated Processing Units (APUs)? Then get ready to scratch: Trinity has arrived and, as of today, it's ready to start powering the next generation of low-power ultra-portables, laptops and desktops that, erm, don't run Intel. The new architecture boasts up to double the performance-per-watt of last year's immensely popular Llano APUs, with improved "discrete-class" integrated graphics and without adding to the burden on battery life. How is that possible? By how much will Trinity-equipped devices beat Intel on price? And will it play Crysis: Warhead? Read on to find out.
Imagination Technologies unveils G6200 and G6400, first two GPUs based on PowerVR Series6
First announced in February of last year, Imagination Technologies has officially announced the licensing availability of its first two GPUs based on the Series6 platform. The PowerVR G6200 and G6400 each promise to bring low power graphics to unprecedented levels and are said to deliver up to 20 times more horsepower than the current generation while also being five times more efficient. In tangible terms, the Series6 GPU cores are capable of exceeding 100 gigaflops and are said to approach the teraflop range. All chipsets based on Series6 are backward compatible with Series5 and fully support OpenGL 3.x, 4.x and ES, along with OpenCL 1.x and DirectX 10. Further, specific models will also support DirectX 11.1 with full WHQL compliance. Poised to shake up the mobile gaming ecosystem, Imagination has already lined up partners that include ST-Ericsson, Texas Instruments, Renesas Electronics and MediaTek. The full PR, complete with all the bragging, can be found after the break.
WebCL scores first demos, GPU accelerated apps headed to your browser
Look, WebGL is great and everything but, in the era of general-purpose GPU computing, we know our 3D chips are capable of much more than just pushing pixels. WebCL is a new standard that brings OpenCL processing to the browser, leveraging the power of your graphics card to perform complex computations. Samsung and Nokia have both released prototype plug-ins, with Sammy's running exclusively in Safari on OS X using NVIDIA chips and Nokia focusing on the 32-bit Windows version of Firefox 4 and AMD GPUs. At the moment, the young technology doesn't offer much to the average user, but demos (after the break) show just how much faster OpenCL can be than traditional JavaScript -- more than 10-times quicker on some tests. Let the countdown to Folding@Home the Web App begin -- we're starting a pool now.
NVIDIA announces GeForce GTX 580M and 570M, availability in the Alienware M18x and MSI GT780R (updated: MSI says no)
We know you're going to be shocked -- shocked! -- to hear this, but NVIDIA's gone and refreshed its high-end line of GeForce GTX cards. The GTX 580M takes the place of the GTX 485M, and NVIDIA's bragging that it's the "fastest notebook GPU ever," capable, we're told, of besting the Radeon HD 6970M's tesselation performance by a factor of six. The new GTX 570M, meanwhile, promises a 20 percent speed boost over the last-generation 470M. Both 40-nanometer cards support DirectX11, OpenCL, PhysX, CUDA, 3D Vision, Verde drivers, Optimus, SLI, and 3DTV Play. As for battery life, NVIDIA's saying that when coupled with its Optimus graphics switching technology, the 580M can last through five hours of Facebook, but last we checked, that's not why y'all are shelling out thousands for beastly gaming rigs. You can find the 580M in the Alienware M17X and M18X (pictured) starting today, though you might have to wait a week or so for them to ship. Meanwhile, the 570M is shipping in the MSI GT780R as you read this, and you'll also find the 580M in a pair of 3D-capable Clevo laptops: the P170HM3 and the SLI-equipped P270WN. Handy chart full 'o technical details after the break. Update: An MSI rep has let us know that contrary to earlier reports, the GT780R is not currently available with the 570M graphics card. The company added that it will offer some unspecified laptop with the 570M sometime in the "near" future. It's unclear if that laptop will, in fact, be the GT780R.
ARM intros next-gen Mali-T604 embedded GPU, Samsung first to get it (update: video)
Promising "visually rich user experiences not previously seen in consumer electronics devices," ARM has introduced its latest embedded GPU architecture, Mali-T604, at its Technology Conference 2010 in California today. Though we're unlikely to see it in devices any time soon, the introduction means that the new design is available to ARM licensees -- and notably, the company points out that partner Samsung will be the first to get hooked up. Considering Sammy competes in the high-end embedded system-on-chip space already with its ARM-based Hummingbird line of cores, adding in the Mali-T604 is probably the next logical step for them. ARM says that it's designed "specifically" with the needs of general purpose GPU computing in mind and includes extensive support both for OpenCL and DirectX, so look for some insane number-crunching capabilities on your next-generation phone, tablet, and set-top box. Follow the break for ARM's press release. Update: We sat down with ARM's Jem Davies to get some more details about the new Mali, and discovered it's only the first of several potential next-gen GPUs to come as part of the Midgard platform -- while this particular processor is available with up to four shader cores, successors might have more. The T604 itself is no slouch, though, as it can theoretically deliver two to five times the performance of the company's existing Mali 400 GPUs core for core and clock for clock -- which themselves run circles around the PowerVR SGX 540 competition if you take ARM at its word. Davies told us that not only does the Mali-T604 do DirectX, it supports the game-friendly DirectX11 as well as the always-popular OpenGL ES 2.0, and will appear in an system-on-a-chip together with an ARM Cortex-A15 "Eagle" CPU, when both are eventually baked into silicon several years down the road. Of course, in the eyes of marketers the future is always now, so get a look at conceptual uses (hint: augmented reality) for ARM's new Mali right after the break.

OpenGL 4.0 arrives, brings more opportunities for general purpose GPU action
What's a Game Developers Conference without some sweet new tools for developers to sink their teeth into? Khronos Group, the association behind OpenGL, has today announced the fourth generation of its cross-platform API spec, which takes up the mantle of offering a viable competitor to Microsoft's DirectX 11. The latest release includes two new shader stages for offloading geometry tessellation from the CPU to the GPU, as well as tighter integration with OpenCL to allow the graphics card to take up yet more duties off the typically overworked processor -- both useful additions in light of NVIDIA's newfound love affair with tessellation and supposed leaning toward general purpose GPU design in the Fermi chips coming this month. Lest you don't care that much about desktop gaming, OpenGL ES (Embedded Systems, a mobile offshoot of OpenGL) is the graphics standard on "virtually every shipping smart phone," meaning that whatever ripples start on the desktop front will be landing as waves on your next superphone. If that holds true, we can look forward to more involvement from our graphics chips beyond their usual 3D duties and into spheres we tend to care about -- such as video acceleration. Now you care, don't ya?
Rumor: The iPhone's next GPU
The Graphics Processing Unit, or GPU, of any modern computing device is an important piece of hardware that offloads 3D graphics rendering from the main processor. At CES 2010 last week, chip manufacturer Imagination Technologies may have spilled the beans on the GPU for the next generation of iPhones. Imagination unveiled the PowerVR SGX545 GPU core design at CES, which is the only mobile phone GPU capable of OpenGL 3.2 and DirectX 10 level effects. The SGX545 also includes OpenCL support, which means that unused processing cycles on the chip can be used to offload work from the main CPU. The SGX545 is also multithreading-aware, and can provide an additional speed jump when used with multi-core processor designs such as the ARM Cortex-A9. Imagination noted that they have produced a test chip for an unnamed "lead partner," which could very well be Apple. The Cupertino Kids have used PowerVR graphics in every iPhone and iPod touch, and many industry pundits believe the next generation of devices could be powered by a variant of the ARM Cortex-A9. Apple is also an investor in Imagination, having purchased a 9.5% stake in the chip manufacturer in 2008 and 2009. So it's very possible that the SGX545 could be churning out pixels in the next handheld you buy from the Apple Store.
NVIDIA launches Fermi next-gen GPGPU architecture, CUDA and OpenCL get even faster
NVIDIA had told us it would be accelerating its CUDA program to try and get an advantage over its competitors as OpenCL brings general-purpose GPU computing to the mainstream, and it looks like that effort's paying off -- the company just announced its new Fermi CUDA architecture, which will also serve as the foundation of its next-gen GeForce and Quadro products. The new features are all pretty technical -- the world's first true cache hierarchy in a GPU, anyone? -- but the big takeaway is that CUDA and OpenCl should run even faster on this new silicon, and that's never a bad thing. Hit up the read links for the nitty-gritty, if that's what gets you going. Read - NVIDIA Fermi siteRead - Hot Hardware analysis Read - PC Perspective analysis
Snow Leopard's Grand Central Dispatch and OpenCL boost video encoding app by 50 percent
It'll take some time before we see the true impact of OpenCL and the newly-open-sourced Grand Central Dispatch on OS X, but we're definitely intrigued by this early report from Christophe Ducommun, developer of MovieGate, who says that shifting his app to use the new tech has increased performance by around 50 percent on the same hardware. Testing on a 2007 2.66GHz quad-core Mac Pro with a GeForce 8800GT, MovieGate MPEG-2 encode speeds went from 104fps under Leopard to 150fps under Snow Leopard, and decoding CPU usage dropped from 165 percent to 70 percent. Now, yes, that's just one app, and most users don't have four cores to play with, but it's still an eye-opening result, and we're definitely hoping it's the start of a trend. [Via MacRumors]
What Snow Leopard feature are you anticipating the most?
Now that we have the actual ship date for Mac OS X 10.6 Snow Leopard (August 28th for those who haven't yet had a cup of coffee to wake them up), it's time to start thinking about what benefits you can gain from the newest member of Apple's cat family.Apple has told us from the start that Snow Leopard is predominantly about streamlining both the size and speed of the operating system. Installing Snow Leopard should take about half the time of performing a Mac OS X 10.5 Leopard install, and it's expected that you'll gain about 7 GB of space back on your hard disk.Snow Leopard is also bringing some new features to the table, including 64-bit support, Grand Central Dispatch's multicore support, and OpenCL, all of which can provide better performance for applications. There are amazing improvements to the Mac OS X Universal Access features, particularly for the vision-impaired. For those who use their Macs in a predominantly Windows office environment, the full built-in support for Exchange should make life much simpler. TUAW would like to know what Snow Leopard feature you're anticipating the most, so we've come up with a short list for you to choose from in a poll. We'll use these results to provide you with detailed coverage about those features. If your favorite improvement or feature isn't on the list, leave a comment and tell us what you're excited about.%Poll-33656%
Snow Leopard shipping August 28th for $29, order now
Well, it's not September, but we're not going to hold an early launch of its performance-focused Snow Leopard OS against Apple. The Apple store has come back online bearing an order page for OS X version 10.6 in Starter, Home Basic, Home Premium, Pro... oh wait, it's just $29 as an upgrade from 10.5. August 28th, that's when, now go 'n get it.While you wait for that order to ship, Apple wants you to know that Snow Leopard's Finder is more responsive, Mail loads messages twice as fast, Time Machine will complete initial backups 80 percent faster, and a 64-bit version of Safari 4 is 50 percent faster than its predecessors. There's even QuickTime X with a redesigned player that lets users view, record, trim and share video. Of course, this release also includes Grand Central Dispatch, a new way for devs to take advantage of multi-core processors as well as OpenCL support to accelerate apps with the help of that idling graphics processor. Oh, and out of the box support for Microsoft Exchange too. All in all, a worthy update, especially for the price.P.S. Requires Intel-based Mac.
