AMD Kaveri Review: A8-7600 and A10-7850K Tested
by Ian Cutress & Rahul Garg on January 14, 2014 8:00 AM ESTProcessor Graphics: Compute and Synthetics
Our GPU Compute tests are designed to stress the integrated graphics of the system using old and new GPU tools. This is where the benefits of Kaveri should come in – if a benchmark is programmed to take advantage of the GCN architecture then the relevant speed up should be observed. In none of the GCN benefits have any use then we are relying on pure grunt to get the top scores.
CompuBench CL Fluid GPU + Computer Vision GPU
CompuBench CL is an OpenCL compute benchmark designed to test some common in-use algorithms. Due to the way it is designed, any OpenCL compatible device can run the benchmarks, and as such we have run both the Fluid Dynamics and Computer Vision portions on the CPU and integrated graphics on each processor we have tested. Here are the GPU results.
GCN really wins out here, showcasing how important OpenCL compliance can be to extract potential compute.

The fact is these "APUs" are really pretty worthless. If you're going to be seriously gaming then you want to get a discrete graphics card, even a low end one. The problem with AMD's strategy here is that the integrated GPU performance is still so anemic that it's only useful for people who want a budget PC and who don't actually play games. Therefore the "benefits" of having both CPU and GPU on one core are highly questionable.ImSpartacus - Thursday, January 16, 2014 - link
That could be solved if we had a much larger GPU on the APU, right?I want to see at least 12 CUs on the top-end APU, preferably more like 16-20 CUs.

Did you miss the whole conversation about memory bandwidth?nader_21007 - Saturday, January 18, 2014 - link
below the charts showing the games performanc, there are two tabs, one for showing avarage frame rate and the other, if you just click on it will show you the suddeframe rates for the apus compared. Minimum frame rate of the iris pro is the lowest and worst among all Apu's compared. It means sudden hangings all over the game. Kaveri and other amd apu's have no such weaknesses because of high performing IGP.Now tell me which is Outperformed?themeinme75 - Saturday, January 18, 2014 - link
the good news is APU-7850/SOC-5200pro just caught up to 4850..cryptik - Monday, March 30, 2015 - link
The R7 consistently beats the Iris Pro. You must have read a different article than everyone else.frozentundra123456 - Tuesday, January 14, 2014 - link
Good review, except he doesn't really address the elephant in the room that even for gaming, a low end cpu like the athlon X4 with a HD7750 will be considerably faster than any APU. So in this regard, I disagree with the conclusions that for low end gaming kaveri is the best solution. It is disappointing actually, that he did not use a HD7750 GDDR5 as the discrete gpu comparison, because that would have given a more direct comparison of how the bandwidth restrictions are affecting Kaveri.I will say though that the low TDP parts seem to get a nice improvement in performance. They actually seem more attractive that the high end, since there is little gaming improvement in the top end vs Richland.

Or something like Pentium G2120 (90$ newegg) and HD7770 (90$ ASUS or MSI on newegg after rebate). The difference between such a setup and a top of the line kaveri chip is not even funny. Kind of tragic, really.andrewaggb - Tuesday, January 14, 2014 - link
I agree. I am extremely dissappointed. Cpu performance and GPU performance barely changed from last year's model. HSA is definitely the future, and Mantle may deliver a healthy fps improvement, but I feel like this product has almost no value at launch. It's all depending on future software.I was actually considering a kaveri for a kids pc... but I'm definitely way better off getting an intel cpu and amd gpu.

I guess they did make big gains on TDP. So it's sorta their version of a haswell refresh. But haswell had a larger improvement in both cpu and gpu performance relative to their previous chip.
