Apple said to be preparing 12-core Mac Pros and 27-inch LED Cinema Displays
AppleInsider has rounded up its stable of "people familiar with the matter" and squeezed them for info on Cupertino's plans for the near term. Firstly, they've heard that a 27-inch version of the currently available 24-inch LED Cinema Display is on its way, sporting a 2,560 x 1,440 resolution and targeted for release "by June." The more exciting tip from those in the know, however, relates to the well aged Mac Pro and its future upgrade path. Apple has apparently firmed up plans to offer 6- and 12-core options (to replace the current 4- and 8-core variants), though the star of the show internally is said to be Intel's Xeon 5600, rather than the similarly specced Core i7-980X that had been rumored. This seems to be motivated by the fact the i7 beast can't do dual-CPU configurations, which are necessary to offer a dozen cores. Pricing for the single Xeon CPU model is expected to be close to the current $2,499 starting sticker, but release dates still elude us.
ST-Ericsson's U8500 brings dual-core 1.2GHz ARM Cortex-A9 to the Android world
Can't get enough of hearing about implementations of ARM's Cortex-A9 MPCore processors? Good. ST-Ericsson's powerhouse U8500 system-on-chip has come a major step closer to appearing in mainstream devices with today's newly announced support for the Android operating system. Having optimized the OS to take advantage of Symmetric Multi Processing -- a method for extending battery life by sharing the load between the two processing cores and underclocking when necessary -- the partner company is now ready to start dropping these 1.2GHz dual-core beasts inside the next generation of smartphones. The claim is that you'll get all that additional power while sacrificing nothing, as devices based on the U8500 would maintain "the cost and power consumption characteristics of a traditional feature phone." We're promised built-in HDMI-out support, 1080p video recording, and 120 hours of audio playback or 12 hours of Full HD video off a 1,000mAh battery -- pledges we'd very much like to see fulfilled.
Texas Instruments introduces ARM-based OMAP 4 SOC, Blaze development platform
Texas Instruments has just made its OMAP 4 system-on-chip official, and garnished the announcement with the first development platform for it, aggressively titled Blaze. We already caught a glimpse of it in prototype form earlier this month, and the thing is quite a whopper -- you can see it on video after the break and we doubt you'll accuse TI of placing form before function with this one. The company's focus will be on promoting innovative new modes of interaction, with touchless gesturing (or "in the air" gesture recognition) figuring strongly in its vision of the future. Looking at the SOC diagram (available after the break), you'll find that its grunt will be provided by the same ARM Cortex-A9 MPCore class of CPU that powers the iPad, though TI claims it will be the only mobile platform capable of outputting stereoscopic 720p video at 30fps per channel. Perhaps its uniqueness will come from the fact that nobody else cares for the overkill that is 3D-HD on a mobile phone, whether it requires glasses or not. It'll still be fascinating to see if anybody picks up the chunky Blaze idea and tries to produce a viable mobile device out of it -- we could be convinced we need multiple displays while on the move, we're just not particularly hot on the 90s style bezel overflow.
Intel crams 48 cores onto stamp-sized processor, wants to do what Cell did
Just when we thought Intel's yet-to-release six-core Core i9 would be the future, the silicon giant drops the bomb yet again with more multi-core madness -- the experimental 48-core Single-chip Cloud Computer (SCC), a.k.a. Rock Creek. While it looks like Intel still has a long way from their 80-core target in 2011, this bad boy packs an impressive 1.3 billion transistors on a 45nm fabrication, but sucks up just 125 watts which is a far cry from Core i9's 130 watts. Intel's stated that their main goal is to use SCC's parallel computation -- a field where high clock speed isn't necessary -- to enhance gesture control. Sounds familiar? Yes, it was Toshiba's SpursEngine, but there's no harm in having a new contender for the challenge. You go, girl!
AMD six-core Opterons get new 'Highly Efficient' and 'Special Edition' siblings
We can beat about the bush or we can just admit that Intel has AMD beat on pretty much all fronts right now. Cognizant of this, AMD sprung the Istanbul server chips months ahead of schedule, and is now seeking to maintain momentum by adding meat to the bone. Three new chips are being added to the server-focused HE (Highly Efficient) Opteron line -- all clocked between 2GHz and 2.1GHz and dissipating 55 watts of heat -- while pure performance considerations are addressed with the SE 2439 and SE 8439, both running at 2.8GHz with 6MB of L3 cache. If we were paranoid, we might think today's leak of Intel's mobile CPU schedule was a coordinated attempt by the market leader to steal some of the limelight from this announcement by Advanced Micro Devices.

GeeXboX 1.2.2 LiveCD media player adds multi-core video decoding, now 1080p is possible
Just a few months removed from its 1.2 update, the latest version of the GeeXBoX LiveCD has added multi threaded video decoding for MPEG-1/2/4 and h.264, which should finally let all users decode even 1080p video on dual- and quad-core systems running Linux. Otherwise there's some additional DVD CSS tweaks, updated MPlayer and codec support, so why not burn a copy and take a tour? Load it RAM, pop out the CD and run whatever discs and hard drive stored media your heart desires.[Via Softpedia]
ARM promises dual-core Cortex A9-based smartphones next year
The world's two most visually engaging smartphones -- the iPhone and the Pre -- share very similar cores based on ARM's Cortex A8 architecture, and with the newer, more advanced Cortex A9 in the pipeline, you can't help but let your mind wander a bit as you envision what twice as much computational power could bring to a handset. The A9 employs more advanced instruction pipelining than its predecessor, but the biggest news has to be the fact that it can pack two or more cores -- and ARM fully expects dual-core A9-based phones to hit in 2010. Of course, power consumption is the biggest constraint when it comes to this category of device, and while the company says that peak drain will exceed that on today's crop of devices, average consumption will actually drop thanks largely to a move from 65nm to 45nm manufacturing processes. Add in 1080p video promised by TI's next-gen OMAP4 silicon wrapped around an A9 core, and you've basically got a home theater in your pocket that's ready to rock for a few hours on a charge. That and Snoop Dogg, of course.
ARM debuts Sparrow multicore netbook processor
We've had our eyes peeled for ARM Cortex-based netbook news, and now among the action this week at MWC '09 we're getting our first look at Sparrow, a Cortex A9 processor aimed squarely at netbook manufacturers. This is a multi-core update to the Cortex A8 (processor of choice for the Palm Pre and Pandora), and it's been speculated that this could be the processor for the next generation iPhone, with "at least triple the computing power of the ARM11 processors found in the [current] iPhone and T-Mobile G1." Toshiba, Pegatron and Wistron are all said to be showing demos of their ARM-powered netbooks at the conference this year, with a company spokesman saying that Ubuntu for ARM will go public in April, with Sparrow phones coming to market sometime in 2010. Additionally, companies like Adobe, On2, and Symbian are said to be "tuning their apps to run on the latest cores from ARM" as we speak.[Via Gadget Mix, Mac Rumors]
Multicore memory in the works?
Multicore processors have become a major part of the consumer mainstream in the past couple years, but if a cryptographic researcher named Joseph Ashwood has his way, the next few years will see the rise of multicore memory. Ashwood's design, which he's had positively reviewed by a team at Carnegie Mellon, allows memory to actually become faster as it gets bigger, due to the way data is organized across individual memory cells. Ashwood says the ratio is almost 1:1 -- doubling size should result in a doubling of speed -- but it's all theory for now, as he's only gotten as far as the software simulation stage. Once a manufacturer commits to the tech, however, Ashwood says chips could be coming off fabs in as little as three months, but it'll be interesting to see who signs up first -- with so many next-gen RAM techs all jostling for position, Ashwood is going to need quite a sales pitch to stand out.[Photo courtesy of MrBill]
Tilera debuts its sixty-four core processor, melts faces
Chipmaker Tilera, clearly bored with the peasant-like core counts of two or four as offered by such pedestrian competition like Intel and AMD, has decided to turn the game up a notch with their latest diabolical creation: the 64-core processor. That's right folks, Tilera's TILE64 is a new RISC CPU aimed at integrated systems like routers, switches, video conferencing, and set-top boxes that can best Intel's finest by a factor of 30, and casually rocks a bandwidth of something like 32TB per second. The new chip circumvents bottleneck problems that can plague CPUs like Intel's multi-core processors by utilizing a unique "mesh" architecture which allows each core to be decentralized and thus able to communicate more freely with any partner in the grid. Tilera believes the technology might open the door to hundreds or even thousands of cores using the new system. Of course, this is a RISC CPU, so clearly the applications in which it will be used differ somewhat from Intel's offerings, but nevertheless, it remains a tantalizing development in the world of multi-core R&D.[Via TG Daily]
Intel demonstrates 80-core processor
Now that the Megahertz race has faded into the distance (we hear it was a myth), Intel is well and truly kicking off the start of a multi-core war with the demonstration of an 80-core research processor in San Francisco last week. It's not the first multi-core processor to reach double figures -- a company called ClearSpeed put 96 cores onto one of its CPUs -- but it's the first to be accompanied by the aim of making it generally available; an aim that Intel hopes to realize within a five year timeframe. The long time frame is required because current operating systems and software don't take full advantage of the benefits of multi-core processors. In order for Intel to successfully market processors with CPUs that have more than say, 4 cores, there needs to be an equal effort from software programmers, which is why producing an 80-core processor is only half the battle. On paper, 80-cores sounds impressive, but when the software isn't doing anything imaginative with them it's actually rather disappointing: during a demonstration, Intel could only manage to get 1 Teraflop out of the chip, a figure which many medium- to high-end graphics cards are easily capable of. The multi-core war may have begun, but the battle will be fought with software, although that's not to say that the hardware side has already been won: apparently the test chip is much larger than equivalent chips -- 275 mm squared, versus a typical Core 2 Duo's 143 mm squared -- and Intel currently has no way to hook up memory to the chip. Hopefully half a decade should be long enough to sort out these "issues."[Thanks, Michael]
