OpenGL ES 3.0 and OpenGL 4.3 squeeze textures to the limit, bring OpenVL along for the ride
Mobile graphics are clearly setting the agenda at SIGGRAPH this year -- ARM's Mali T600-series parts have just been chased up by a new Khronos Group standard that will likely keep those future video cores well-fed. OpenGL ES 3.0 represents a big leap in textures, introducing "guaranteed support" for more advanced texture effects as well as a new version of ASTC compression that further shrinks texture footprints without a conspicuous visual hit. OpenVL is also coming to give augmented reality apps their own standard. Don't worry, desktop users still get some love through OpenGL 4.3: it adds the new ASTC tricks, new visual effects (think blur) and support for compute shaders without always needing to use OpenCL. All of the new standards promise a bright future in graphics for those living outside of Microsoft's Direct3D universe, although we'd advise being patient: there won't be a full Open GL ES 3.0 testing suite for as long as six months, and any next-generation phones or tablets will still need the graphics hardware to match.
ARM's eight-core Mali GPUs promise 'dramatic' boost to mobile graphics
The current flagship for ARM's mobile graphics technology is undoubtedly the Galaxy S III, which contains a quad-core Mali 400 GPU and delivers some wild benchmark scores. By the end of this year though, we should see a whole new generation of Malis -- not just a Mali 450 for mid-range handsets, but also the quad-core T604 and the eight-core T658, which are based on ARM's Midgard architecture and are taking forever to come to market. Now, to whet our appetites even further, ARM has just added three more variants of the chip to its roster, which can almost be considered the next-next-generation: the quad-core T624, and the T628 and T678, which are both scalable up to eight cores. The trio's headline feature is that they promise to deliver at least 50 percent more performance with the same silicon area and power draw, with the explicit aim of delivering "console-class gaming," 4K and even 8K video workloads, as well as buttery 60fps user interfaces in phones, tablets and smart TVs. The premium T678 is aimed at tablets specifically, and in addition to allowing up to eight cores also doubles the number of math-crunching ALUs per core, which means that its compute performance (measured in gigaflops) is actually quadrupled compared to the T624. However, there's one other, subtler change which could turn out to be equally important -- read on for more.
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.
Qualcomm hires former AMD CTO, makes 'em pay for dropping mobile
Qualcomm is hiring AMD's former CTO Eric Demers to help the company produce a blockbuster mobile graphics chip. It needs the silicon for its big push for smartphone dominance (and tablets running Windows RT) in the face of strong competition from Imagination Technologies' Series 6 PowerVR and NVIDIA's Tegra 3. Demers' first job will be to merge Qualcomm's in-house Adreno team with ATI's Imageon mobile graphics chip team, which AMD flogged off for $65 million back in 2009 -- a move Sunnyvale is probably regretting now that it too is trying to get its hardware into mobile devices, unless it included a do-over clause in the sales contract.
NVIDIA rebadges GeForce 500M chips in preparation for Ivy Bridge release in 2012
NVIDIA has released a new range of mobile graphics chips that bring the features of last year's 500M series down to a lower price point. Keen-eyed observers might notice the GT635M is remarkably similar to the GT555M, albeit with slightly faster memory bandwidth. The GT630M is a dead ringer for the GT540M/GT550M and the 48 CUDA core GT610M could be the GT520M if you squint at it in bad light. It's all rather detailed and low-key, but NVIDIA reminded us that it'll launch "something more exciting" around the time Ivy Bridge makes its debut in 2012 -- very possibly those 28nm Kepler chips we've been drooling over for a while? [Thanks, Omar]
NVIDIA's quad-core Kal-El used to demo next-gen mobile graphics, blow minds (video)
You might think yourself too grown-up to be wowed by shiny, glittery things, but we doubt many will be able to watch NVIDIA's new Glow Ball tech demo without a smidgen of childlike glee. Built to run on the company's quad-core Kal-El processor, it shows us the first example of true dynamic lighting on mobile devices and also throws in some impressive physics calculations like fully modeled cloth motion. Instead of the pre-canned, static lights that we see on mobile games today, NVIDIA's new hardware will make it possible to create lighting that moves, fluctuates in intensity, and responds realistically to its environment -- all rendered in real time. The titular glow ball can be skinned with different textures, each one allowing a different amount and hue of illumination to escape to surrounding objects, and is directed around the screen using the accelerometer in your tablet or smartphone. NVIDIA demoed the new goodness on a Honeycomb slate with 1280 x 800 resolution and the frame rates remained smooth throughout. In order to emphasize the generational leap that we can expect with Kal-El, the company switched off two of the four cores momentarily, which plunged performance down to less than 10fps. That means the simulations we're watching require a full quartet of processing cores on top of the 12-core GPU NVIDIA has in Kal-El. Mind-boggling stuff. Glow Ball will be available as a game on Android tablets once this crazy new chip makes its way into retail devices -- which are still expected in the latter half of this year, August if everything goes perfectly to plan. One final note if you're still feeling jaded: NVIDIA promises the production chip will be 25 to 30 percent faster than the one on display today. Full video demo follows after the break.
NVIDIA refreshes notebook graphics with GeForce GTX 560M, attracts ASUS, MSI, Toshiba and Alienware
If you've enjoyed NVIDIA's fine tradition of merely bumping along its GPUs time and again and affixing a new badge, you'll like the GeForce GTX 560M -- it's much like last year's GTX 460M, but with more bang for the buck than ever. ASUS, MSI, Alienware, Toshiba and Clevo have all committed to new notebooks bearing the graphics processor in light of the potent performance NVIDIA claims it will bring: Namely, those same 192 CUDA cores (now clocked at 1550MHz) and up to 3GB of GDDR5 memory (now clocked at 1250MHz, with a 192-bit bus) should enable the latest games to run at playable framerates on a 1080p screen with maximum detail -- save antialiasing. Of course, that assumes you've also got a recent quad-core Sandy Bridge processor and gobs upon gobs of RAM, but NVIDIA also says that with the built-in Optimus switchable graphics, those same potent laptops should be able to manage five hours of battery life while idling. If you're looking for some inexpensive discrete graphics, however, NVIDIA's also got a refresh there, as the new GeForce GT 520MX bumps up all the clock speeds of the GT 520M. When can you expect a mobile GPU to knock the GTX 485M off its silicon throne, though? Glad you asked: a chart shows a "Next-gen GTX" coming late this year. Meanwhile, see what NVIDIA says the GTX 560M's capable of in the gallery below and a video after the break. %Gallery-124725%
Qualcomm's 1.5GHz dual-core MSM8660 destroys the competition in majestic benchmark run
Take the 1GHz Scorpion core residing in Qualcomm's current flagship Snapdragon, the MSM8x55, duplicate it, overclock the resulting pair by 50 percent, and give them improved graphics in the form of Adreno 220. What do you get? A barnburner by the unsexy name of MSM8x60. Yes, the 1.5GHz Mobile Development Platform Qualcomm loosed on the world at CES earlier this year has found itself prostrate on a test bench, where it has produced some of the finest graphical performance scores yet seen on a mobile device. The taxing OpenGL ES 2.0 test you see above shows the new Snapdragon doubling the frame rates churned out by Motorola's mighty Atrix 4G (which admittedly has to work harder thanks to its higher-res display) and completely embarrassing older generation hardware like the EVO 4G. That's a theme carried on throughout AnandTech's benchmarking, which you may explore in full at the source link. If you're wondering when this world-beating dual-core chip will be coming to market, the answer is that it's already inside HTC's imminently upcoming EVO 3D and Pyramid devices, albeit running at a tamer 1.2GHz. Exciting, eh? P.S. - Do take note that the Qualcomm dev platform was plugged into the wall during these tests and was not subject to any power management software that may have otherwise restrained its performance as on the retail chips under test. Moreover, the Egypt benchmark can only run at native resolution, which is what's causing some seemingly aberrant results such as the iPhone 4 (960 x 640) ranking below the iPhone 3GS (480 x 320).
AMD Radeon HD 6970M reviewed: major leap from HD 5870M, not quite a GTX 485M
What has 960 shaders, two gigabytes of dedicated GDDR5 memory with throughput of 115.2GBps, and the ability to churn 680 million polygons each and every second? Yes, the Radeon HD 6970M. AMD's fastest mobile chip to date has been doing the review rounds recently and the response has been unsurprisingly positive. Most modern games failed to trip up the 6970M even at 1920 x 1080 resolution, though the usual suspects of Crysis and Metro 2033 did give it a little bit of grief. All in all, the leap from the HD 5870M was significant, although NVIDIA's still relatively new GeForce GTX 485M has managed to hold on to its crown as the most powerful GPU on the mobile front. Benchmarks, architectural details, battery life tests (what battery life?), and value-adding enhancements await at the links below.
NVIDIA makes GeForce GT 500M family official, introduces GTX 485M as its fastest mobile GPU
Yes, NVIDIA's naming scheme really is all over the place, but here's what you need to know: as of today, the fastest mobile GPU coming from Jen-Hsun Huang's team will be the GeForce GTX 485. That chip will be equipped with a 256-bit memory interface and GDDR5 RAM and succeed the GTX 480M as the king of the (relatively) mobile castle. Moving up in numbers, but not performance, the new GT 520M, 525M, 540M, 550M, and 555M represent very mild refreshes of their 400M series counterparts. We were initially unimpressed by NVIDIA's decision to keep things stagnant but for some more aggressive clock speeds at the same TDP envelopes, but a recent review of the earlier-launched GT 540M showed appreciable gains from its predecessor, so maybe these graphics gurus actually know what they're doing. We've gathered some imagery of early units sporting NVIDIA's new graphics hardware -- notably paired with Intel's Sandy Bridge CPUs -- in the galleries below, but we'll surely have more for you as we explore the halls of CES. After all, NVIDIA has an awesome 200 design wins combining its tech with Intel's latest, there should be plenty of previously unseen hardware for us to find. In the mean time, skip past the break to see a couple of benchmark runs showing off NVIDIA's new graphics processors. %Gallery-112252%%Gallery-112060%
2011 to bring 200 PCs combining GeForce GPUs and Sandy Bridge, first laptops to be quad-core
What's NVIDIA got up its sleeve for CES, you ask? A whole host of Sandy Bridge laptop and desktop machines, by the sound of its latest press release. The green giant of graphics has proudly announced a new record of 200 OEM design wins for Intel's incoming CPUs. The big draw of Sandy Bridge is that it's the first processor to include an integrated GPU embedded directly within its die, which is projected to improve power efficiency and overall performance -- though clearly it hasn't been impressive enough to get PC vendors to abandon discrete graphics chips. If anything, they seem to be going in the other direction and insisting on a discrete GPU as well. In other news, whether with or without NVIDIA's help, the first Sandy Bridge laptops will feature quad-core parts. Such is the word directly from Intel, with one insider adding that the dual-core debutants will get their chance a month after CES, around the middle of February. Skip past the break for NVIDIA's boastful PR or hit the source for more on Intel's plans.
Apple to rely on Intel's Sandy Bridge graphics in future MacBooks, AMD GPUs in MacBook Pros?
Apple will use Intel's Sandy Bridge CPUs in its future laptops, no surprises there, but what's interesting about these forthcoming machines is that some of them might rely solely on Intel's chip for both general and graphical processing tasks. That's the word from the usual "sources familiar with Apple's plans," who expect "MacBook models with screen sizes of 13 inches and below" to eschew the inclusion of a discrete GPU and ride their luck on the improved graphical performance of Intel's upcoming do-it-all chip. There are currently no sub-13.3-inch MacBooks, so the suggestion of one is surely intriguing, but the major point here seems to be that NVIDIA's being left out of the Apple party, because MacBook Pros are also predicted to switch up to AMD-provided graphics hardware. All these changes should be taking place with Apple's next refresh, which is naturally expected at some point in the new year. Although, as CNET points out, this could all be just a massive negotiating ploy to get NVIDIA to play nicer with its pricing, we're inclined to believe Intel has finally gotten its integrated graphics up to a level where it pleases the discerning tastemakers at Apple.
NVIDIA GeForce GT 540M refreshes mobile graphics midrange (update: hands-on pics)
Uh oh, just as we thought NVIDIA had moved beyond its penchant for rebadging hardware, here comes the vanguard of its 500M mobile GPU series -- which happens to be specced nearly identically to what's already on offer in the 400M family. The GT 540M chip maintains the same 96 CUDA cores and 128-bit memory interface as the GT 435M, but earns its new livery by cranking up graphics and processor clock speeds to 672MHz and 1344MHz, respectively, while also taking the onboard memory to a max speed of 900MHz. Power requirements have been kept unchanged, mind you, and NVIDIA itself admits it's exploiting the maturation of the production process to just throw out some speedier parts. China gets the GT 540M immediately, courtesy of Acer, while the rest of the world should be able to buy in at some point next month. Jump past the break for the full press release. Update: We've managed to track down the particular Acer model that'll mark the GT 540M's debut, it's called the Aspire 4741G. The option we saw came equipped with a 2.66GHz Intel Core i5-480M processor, 4GB of RAM, a 640GB HDD, a Blu-ray disc drive, and a 14-inch screen up top. There's not much, aside from the new top cover design, to really distinguish this from the rest of Acer's Aspire line, with the keyboard in particular being the very same one that we've witnessed on Timeline series machines for over a year now -- comfortable, well spaced, but exhibiting quite a bit of flex around the Enter key.

NVIDIA trots out GeForce 400M series laptops, shows off StarCraft II gameplay (video)
You might have hoped that NVIDIA's introduction of the 400M series of mobile GPUs would bring about a slew of hot new laptops to drop into our gaming boudoirs, but we are in fact left facing more of the same. Externally, anyhow. The chipmaker rolled out the green carpet for a set of upcoming machines in London today, but they were refreshes, rather than overhauls, of current hardware. The big news is to be found within, as the new GTX 460M has made a home inside the updated ASUS G53, Toshiba Qosmio X505, and MSI GT663. The common thread among these three is that they're all big and hefty, and all emit a subtle vroom sound every time you touch them. What we learned from NVIDIA today is that the GTX 480M will remain an exotic (you might even call it quixotic) GPU reserved for large-screen gaming stations, the GTX 470M will similarly be an enthusiast part, and the GTX 460M will be the company's big play for the mainstream performance market. It also became clear that even the third GPU in the company's mobile hierarchy will need quite a bulky cooling setup (and a proportionately huge charger) to do its job, but NVIDIA's promises of much-improved performance might just make it worthwhile. As to the more sane among us, there was a selection of pleasingly thinner machines, like the ASUS N53 and Acer Aspire 5745, which make do with the lower-specced GT 420M and GT 425M graphics chips. Those are expected to be NVIDIA's biggest sellers, and the video demo after the break of the 425M churning through StarCraft II is certainly appealing. We should note, however, that the latest (though definitely not greatest) Prince of Persia game was also on tap on one of these machines and its frame rate gave us a delightful old-timey feeling any time we entered combat with its emulation of stop-motion animation. So, as ever, it's looking like great graphics will require great rigs, but we can probably expect a decent -- not game-changing (get it?) -- leap in performance among the lighter options as well.%Gallery-101899%
NVIDIA GTX 470M highlights rollout of 400M mobile GPU series
Not everybody needs the world's fastest mobile GPU, so NVIDIA is sagely trickling down its Fermi magic to more affordable price points today. The 400M family is being fleshed out with five new midrange parts -- GT 445M, GT 435M, GT 425M, GT 420M and GT 415M, to give them their gorgeous names -- and a pair of heavy hitters known as the GTX 470M and GTX 460M. Features shared across the new range include a 40nm fab process, DirectX 11, CUDA general-purpose computing skills, PhysX, and Optimus graphics switching. 3D Vision and 3DTV Play support will be available on all but the lowest two variants. NVIDIA claims that, on average, the 400M graphics cards are 40 percent faster than their 300M series counterparts, and since those were rebadges of the 200M series, we're most definitely willing to believe that assertion. Skip past the break for all the vital statistics, and look out for almost all (HP is a notable absentee, while Apple is a predictable one) the big-time laptop vendors to have gear bearing the 4xxM insignia soon.
HP crams Fermi-based Quadro 5000M GPU inside 17-inch EliteBook
Gotta live up to the name, right HP? NVIDIA's new pro graphics solution for mobile creatives, the Quadro 5000M, was unsheathed only yesterday but HP appears to have been first in line to get some of that new 40nm goodness. Electronista reports that the world leader in PC shipments is readying a 5000M solution for its 8740w EliteBook, which will bring 320 CUDA cores and a jumbo 2GB of dedicated memory to the party. That comes replete with the latest DirectX 11 and OpenGL 4.1 compatibility, naturally, as well as a bunch of pro-friendly computational enhancements. Dell's also going to be offering a 5000M-equipped rig, but lest you get too excited, bear in mind that getting the current best Quadro-equipped 17-incher from HP costs north of $3,000, so affordability is clearly not a priority here. Skip past the break for NVIDIA's joyous press release announcing the new Quadro chips.
EVO 4G loses 30fps limit thanks to devoted community (video)
Whatever the reason HTC instituted that 30fps cap on the EVO's graphical output, the issue has just been remedied by -- surprise, surprise -- coders over at xda-developers.

NVIDIA GeForce GTX 480M reviewed: fastest mobile GPU to date
It's one thing to have a product called the world's fastest on paper, but it's another thing entirely to have the benchmarks confirm it. NVIDIA's GeForce GTX 480M has been swooned over for months now, but it just recently hit the hardcore review sites in a big way. Frankly, there's not a whole lot to say about the thing at this point: it's simply the fastest mobile GPU to date, with Hot Hardware finding it to be "significantly faster in nearly all gaming benchmarks," with just one title showing the Mobility Radeon HD 5870 as the champ by only a few frames. If you've been searching for the fastest mobile GPU in town, you're wasting your time looking any harder; 'course, all of that power consumes an insane level of energy, so true road warriors will certainly want to look elsewhere. Critics pointed out that energy consumption and excess heat were real issues, though both of those are easily overlooked when you're able to take a beastly laptop to a LAN party rather than your desktop.

NVIDIA shows 16 new Optimus laptops at Computex, teases GTX 460M GPU
Just in case you were wondering where and when you might get a taste of the Optimus elixir, NVIDIA has handed us a detailed list of Computex debutants that will be taking the graphics switching technology with them to retail. A total of sixteen new Optimus machines are on show in Taipei, and although ASUS is still the biggest purveyor (with six SKUs, not counting previously announced products), Lenovo and Acer have also jumped on board, with the IdeaPad Y460 and a pair of Packard Bell EasyNotes, respectively. Notably, the FX700 above from MSI is marked as using an "unannounced" next-gen graphics chip, which we suspect might be the GTX 460M, a mobile GPU that NVIDIA is showing, but not talking about yet. Guess that'll be slotting in just below the recently unveiled GTX 480M. We've got pictorial evidence of the 460M's existence after the break, along with the full list of new Optimus-ized machines, which you can also scope out in the gallery below.%Gallery-94167%
NVIDIA GeForce GTX 480M: 'world's fastest' mobile GPU now official, landing in June
NVIDIA has just announced that the GTX 480M, the mobile re-spin of its extravagantly overpowered Fermi desktop parts, will be arriving in the middle of next month. Touted as the world's fastest mobile graphics processor, this chip will bring 352 CUDA cores and a 256-bit memory interface to up to 2GB of GDDR5 RAM. These are clear and convincing advances over the incumbent Green Team leader, the 360M, but things start to look a little worrying when we check the 480M's clock speeds. The processor speed is nearly halved from the desktop GTX 480, at 850MHz, the memory does only 1,200MHz, and the graphics run at 425MHz -- we didn't know anything worthwhile even operated below 500MHz these days. Either way, you're getting a computing powerhouse, with the 480M's 897 gigaflops comfortably dwarfing its predecessor's 413 and promising almighty tessellation performance. What it all means with regard to keeping your frame rates up while traversing the Terminus Systems, we can't yet say. We'll let the benchmarking gurus figure it out -- go past the break for the full press release and spec sheet.
