APU Enhanced Software And The User Experience

AMD A10-4600M Review: Mobile Trinity Gets Tested
By

Perhaps you’ve seen some of our recent efforts to work with AMD to explore today’s state of general-purpose compute acceleration, such as What Does DirectCompute Really Mean For Gamers? and OpenCL In Action: Post-Processing Apps, Accelerated. We have more of those stories planned. But, to be perfectly honest, I never felt very compelled by the potential of accelerated apps until I saw the stuff currently being worked-on at AMD’s Trinity briefing.

A number of applications able to run on any OpenCL-enabled product, along with some others optimized for AMD-specific features, are either already available or nearly ready.

In many cases, the improvements being folded in are qualitative, not quantitative. As a result, we can’t really benchmark them. This is the stuff we talked about on page one of this story, which AMD is hoping people will think about when it comes time to buy. Let’s consider some of the applications that Tom’s Hardware readers might use.

AMD Steady Video

Steady Video is a real-time video enhancement tool that can help reduce the shaky effect of poorly-recorded video. It’s also AMD’s poster child for APP acceleration. The feature’s benefits are easy to understand when you them in action. AMD now has Steady Video 2.0 plugins for IE, Firefox, Chrome, and Windows Media Player.

Is this a must-have feature? Does it make sense to skip Intel’s Quick Sync technology in favor of this piece of software? I don’t think so. As cool as it is, most of the content that I, personally, watch isn’t shaky home video. In fact, I’m not even sure I’d use it. Nevertheless, AMD’s application of technology is unquestionably cool to watch in action. Check out a demo by searching the Web for ”AMD Steady Video.”

VLC Media Player

This is an open source, cross-platform, free multimedia player. AMD’s support for VLC is smart, since its open source foundation means there is a large user base that stands to benefit from acceleration support.  Optimizations include a real-time OpenCL-based de-noise filter and support for AMD Steady Video. Again, neither addition is a must-have feature, but they’re there in development for VLC users who want to try them out.

WinZip 16.5

This is probably the highest-profile software available with OpenCL-based enhancements, and our testing shows that acceleration makes a real difference in compression performance. Corel’s cooperation seems like real win for AMD, though a closer look at the benchmark results reveals that the company’s best effort still isn’t able to overtake Intel’s Sandy Bridge architecture. Essentially, we’re presented with a feature that brings A10-4600M compression performance very close to the Core i5-2450M. The inclusion of acceleration seems less impressive when it’s needed to achieve parity with the competition.

We’re also compelled to call AMD out on this one. The whole point of a standard like OpenCL is industry-wide adoption. However, because AMD worked with Corel on enabling OpenCL support, both companies are locking out Intel and Nvidia. Although AMD’s fans won’t mind, were the roles in this drama reversed, there would be an outcry. Perhaps it’s a good thing that the outcome remains pretty darned even.

Media Encode Acceleration – OpenCL and VCE

Arcsoft’s MediaConverter 7.5, CyberLink’s MediaEspresso 6.5, and the x264 front-end HandBrake (in an upcoming revision) are all able to take advantage of AMD’s programmable shader hardware and fixed-function VCE logic for accelerated video transcoding. The feature is great for AMD owners. Unfortunately, the improved performance isn’t quite as fast as Intel’s Quick Sync capability, according to our test data.

MotionDSP vReveal

This video-quality enhancement application is an ideal showcase for AMD Steady Video and GPU-accelerated rendering. The worst thing I can say about this tool, which has some very high-end roots, is that it’s limited to a very specific purpose and might not appeal to a wide audience. If you rely on vReveal to fix the quality of your captured video on a regular basis, however, an AMD-based APU or discrete card might make sense.

Photoshop CS6

Photoshop CS6 makes use of over 30 GPU-accelerated features, including liquefy, transform, warping, and blur rendering. Depending on the work you do in Adobe’s software, you may not run into those features very often at all. But when you do need those specific features, OpenCL-based acceleration can make a big difference.

The caveat, of course, is that GPU acceleration works on any OpenCL-enabled device, including Intel’s HD Graphics 3000 engine, tested in this piece. In our experience, real-time filters like liquefy actually work faster on the Core i5-2450M compared to the A10-4600M. The moral of this story: don’t assume an APU is faster just because the app has GPU acceleration.

GIMP

Another popular open source application, GIMP is an image manipulation program in the same vein as Photoshop that also boasts powerful features and a large user base. An upcoming release adds support for 19 accelerated OpenCL filters. We didn’t have time to run this one first-hand, and it won’t be publically available for a while yet. So, we don’t have any experiential feedback. But it is great to see the open source community on-board.

Adobe Flash Player 11

Flash has an immense user base, and the newest version of this plug-in includes support for 3D graphics

We checked out Tanki Online and the Unreal Engine 3 Flash demos, and were extremely impressed at the detail that Flash achieves in a browser window.

Keep in mind that Flash is accelerated by any GPU though, and although AMD APUs tend to be stronger, we noticed that Intel HD Graphics 3000 was also sufficient to run the demos we mentioned.

AMD Quick Stream Technology

This is a proprietary application that prioritizes Internet traffic to ensure that video streams are given preferential treatment, minimizing stuttering. It’s a great idea that I hadn’t previously seen implemented specifically for video streaming. and I don’t think I’ve seen it done specifically for video streaming yet. Having said that, I have used freeware network bandwidth prioritizing utilities in the past with positive results.

Game Image Quality

For most gamers, image quality is an important consideration, and Intel has a bad reputation for delivering less-than-stellar visuals—particularly poor anisotropic filtering.  Although SemiAccurate reports that the situation is much improved on Ivy Bridge, Sandy Bridge still suffers from terrible filtering quality.
