AMD Kaveri Review: A8-7600 and A10-7850K Tested
by Ian Cutress & Rahul Garg on January 14, 2014 8:00 AM ESTCPU Performance: Continued
Xilisoft Video Converter 7 - link
The XVC test I normally do is updated to the full version of the software, and this time a different test as well. Here we take two different videos: a double UHD (3840x4320) clip of 10 minutes and a 640x266 DVD rip of a 2h20 film and convert both to iPod suitable formats. The reasoning here is simple – when frames are small enough to fit into memory, the algorithm has more chance to apply work between threads and process the video quicker. Results shown are in seconds and time taken to encode. XVC also offers acceleration via CUDA and AMD APP, so if these are available on the CPU we offer results with and without.
With large frame data, the IGP on Kaveri does not particularly help much.
For smaller frames however, there is an advantage to enabling the AMD APP function.
HandBrake v0.9.9 - link
For HandBrake we do the same files as XVC but convert them into the default format Handbrake offers upon loading the software. Results shown are in Frames Per Second.
Handbrake loves cores, threads and MHz
Adobe After Effects 6
Published by Adobe, After Effects is a digital motion graphics, visual effects and compositing software package used in the post-production process of filmmaking and television production. For our benchmark we downloaded a common scene in use on the AE forums for benchmarks and placed it under our own circumstances for a repeatable benchmark. We generate 152 frames of the scene and present the time to do so based purely on CPU calculations.
7-Zip 9.2 - link
As an open source compression tool, 7-Zip is a popular tool for making sets of files easier to handle and transfer. The software offers up its own benchmark, to which we report the result.
PovRay 3.7 - link
PovRay historically loves threads, MHz and IPC. The standard benchmark from PovRay is what we use to test here.
TrueCrypt 7.1a - link
TrueCrypt is an off the shelf open source encoding tool for files and folders. For our test we run the benchmark mode using a 1GB buffer and take the mean result from AES encryption.

I'd like an APU with enough GPU power to run all the high quality options in MadVR. Would make a very nice HTPC chip.thomascheng - Tuesday, January 14, 2014 - link
I think Mantle can make that happen, but will see how much support they get.MrSpadge - Tuesday, January 14, 2014 - link
Mantle has nothing to do with GP-GPU, that's not using DirectX anyway.JDG1980 - Tuesday, January 14, 2014 - link
My discrete 7750 couldn't handle Jinc scaling in MadVR (at least not without dropping frames on some 1080i test clips), so this is going to be another generation or two in the future.The PS4 APU could probably do it, if that was available in a generic PC form factor.

Add to that DDR4 and/or 4 memory channels, or at least a large on-package buffer like Crystal Well.yankeeDDL - Wednesday, January 15, 2014 - link
But the whole point of HSA is to get the GPU to do CPU work that it could do better (like FP).So you wouldn't need more CPU cores at all.
Look at it this way: AMD's CPU is less efficient than Intel's, while the GPU is more efficient.
Having a CPU-imbalanced APU, would put it in a tough(er) spot to compete against Intel. A GPU imbalanced, as Kaveri is, would improve the lead than it already has on the GPU side.
Now imagine that HSA kicks in, and the GPU lead translates directly in CPU lead ...

This is true. I hope we see more articles as adoption of HSA starts to take hold.It is too bad they are far behind in CPU power, but AMD has the right strategy. Either way, some things are better done on the GPU. AMD just has more benefit than Intel to get things moving that way sooner with their GPU advantage and CPU disadvantage. Intel will have no choice but to follow that lead.

http://www.extremetech.com/computing/174632-amd-ka...hsa does well on amd main thing they marketed in libreoffice.

I'm normally not one to speak about other articles, but those are all OpenCL benchmarks. The OpenCL HSA driver won't be released for another quarter. And the HSA SDK is similarly far off.http://www.anandtech.com/show/7677/amd-kaveri-revi...

What a bencmark of a review. I learned a lot. Great. Thanx.
