GPGPU Benchmark
It's ATI Stream versus Nvidia's CUDA in this GPGPU-on-IGP shootout. We benchmarked the Cyberlink Espresso video converter, which is conveniently optimized to take advantage of both CUDA and ATI Stream and seems to be an ideal test.
Maybe not so ideal after all, as these results look somewhat strange.
We had a few odd occurrences of note during testing. First of all, when Espresso was run on the Nvidia 9300 chipset, the program gave us the option to turn hardware acceleration on or off, presumably to enable/disable the CUDA optimizations. The strange thing is that when optimizations were enabled, the video encoding took longer, which is the opposite of what we expected. We asked Nvidia about this phenomenon, and they claim that their testing shows even a 3 GHz Core 2 Duo E6850 should demonstrate a performance increase with CUDA enhancements enabled.
Nvidia also pointed out that these results are misleading unless the resulting encoded video is bit-for-bit identical, and they claim that their encoding is of a higher quality than the video resulting from the ATI Stream optimizations. They were also concerned that the version of Cyberlink Espresso AMD had provided was not a publically available build. We were actually working with both companies (and Cyberlink) on an image quality comparison, even before 785G showed up, so you can expect more detailed coverage there as soon as that project comes together.

AMD 785G Update - Multi-Channel LPCM is not Available
or at least thats what AMD says accordign to anandtech:

Great article..thanks for including the GPGPU benchmarks
Be nice to see those vs. the fastest i7 and it's respective power draw.
Fair do's to AMD. They've bounced back, and given the market some products that can compete with both Intel (CPU's) and nVidia (GPU's). Seems like it's only nVidia that has kept Intel's head above water in the GPU market..the G45 couldn't even play Blue-Ray properly, let alone produce decent frame rates even in slightly older games.
If I was in AMD's shoes right now I'd push the advantage of GPGPU processing, in addition to low-cost Athlon II/Phenom II processors. Only thing that doesn't appeal to me is the naming conventions, which confuse the user into thinking higher numbers mean more performance..that really turned me off nVidia. The 785G is alright because it suggests a slightly modified design rather than a brand new one (nice to see them squeezing everything out of it and developing even better drivers), but the integrated HD4200 being slower than HD3300? Hmm, c'mon guys..that might cheese off a few people.
Finally, the article does lead me to ask: is nVidia doing the 9400 for AM3? If not, is it down to some competition law or something? The 8200 game results look very weak..they're even on par with the Intel G45 on occasion. An nVidia 9 series IGP for the AMD platform would obviously be better.
p.s.
I think Mother Earth is far better served by the US population, which is predicted to mushroom in a relatively short space of time..I'll settle for the lesser evil I think, and get that shiny new CPU.

I think you've missed out the words "not" and "cloud" from your quote
Anandtech is reporting that retail 785G motherboards typically won't actually support multi-channel LPCM. Any truth to this?
AMD chips still can't run standard windows Apps properly without cashing, so as far as I am concerned, Intel is a solid winner.
(every AMD I have been on has had an issue with some very basic program, ranging from Nero Burning Rom to something as simple as Microsoft Word (03/07))
Hey, this review is giving me ideas....
and now i'm slightly confused...
I was going to assemble an intel 5200+ Biostar g41 for a simple home use PC, but now I am seriously considering 785G. I am not really into gaming. All I want is a graphic good enough to play bluray with good onboard sound card.
Anyway, keep up the good work. This is the kind of review which a novice like me am looking at and depending upon when trying to buy a new PC. Thanks!!
