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 release.

Intel details 4th-gen Core’s HD 5000, Iris and Iris Pro graphics: up to 3X faster, 3-display collage mode

Intel details 4thgen Core's HD 5000, Iris and Iris Pro graphics up to 3X faster, 3display 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.

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.

OpenCL mod for the Kindle Fire HD reveals untapped graphics potential (hands-on video)

Posted on by

If a Kindle Fire HD could run OpenCL accelerated graphics, it'd look like this handson 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 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

Posted on by

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.

Primed

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)

DNP ARM's MaliT604 makes its official device debut, we get a first look at the nextgen GPU handson video

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.

ARM claims new GPU has desktop-class brains, requests OpenCL certificate to prove it

ARM claims new GPU has desktopclass 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.
