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.

"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."I get your point, but its not really a review issue , its a product issue. AMD certianly cant compete inthe CPU arena. They are good enough, but nowhere near Intel 2 generations ago (Sandy Bridge from 2011). They have a better integrated GPU, so in that sense its bte best integrated GPU, but as you mentioned, if you are into gaming, you can still get better performance on a budget by getting a budget add in card, so why bother with Kaveri?

"I get your point, but its not really a review issue , its a product issue."Well, the point of a review is to highlight whether or not a product is worth purchasing.

I agree. He should have made analysis from the viewpoint of different computer purchasers. Just one paragraph would have worked, to fill in the blanks.. something like these -1. the gamer who will buy a pricier discrete GPU
2. the HTPC builder
3. the light gamer + office productivity home user
4. the purely office productivity type work person

I can understand why he didn't use a 7750/70 with GDDR5 ... all sub $70 video cards I've seen come with ddr3. Your bucking up by spending that additional 30-60 bucks (sales not considered)Computer Bottleneck - Tuesday, January 14, 2014 - link
The R7 240 GDDR5 comes in at $49.99 AR---> http://www.newegg.com/Product/Product.aspx?Item=N8...So cheap Video cards can have GDDR5 at a low price point.

That's a sale though.. it's a $90 card.. I mean sure if it becomes the new norm.. but that hasn't been the case for the past couple of years.ImSpartacus - Thursday, January 16, 2014 - link
Yeah, if you get aggressive with sales, you can get $70 7790s. That's a lot of GPU for not a lot of money.yankeeDDL - Tuesday, January 14, 2014 - link
Do you think that once HSA is supported in SW we can see some of the CPU gap reduced?I'd imagine that *if* some of the GPU power can be used to help on FP type of calculation, the boost could be noticeable. Thoughts?

Yes, that is probably why the CPU floating point calculation isn't as strong, but we won't see that until developers use OpenCL and HSA. Most likely the big selling point in the immediate future (3 to 6 month) will be Mantle since it is already being implemented in games. HSA and OpenGL 2.0 are just starting to come out, so we will probably see more news on that 6 months from now with partial support in some application and full support after a year. If the APUs in the Playstation 4 and Xbox One are also HSA supported, we will see more games make use of it before general desktop applications.yankeeDDL - Tuesday, January 14, 2014 - link
Agreed. I do hope that the gaming consoles pave the way for more broad adoption of these new techniques. After all, gaming has been pushing most of the innovation for quite some time now.CPU improvement has been rather uneventful: I still use a PC with an Athlon II X2 @ 2.8GHz and with a decent graphic card is actually plenty good for most of the work. That's nearly a 5 year old CPU and I don't think there's a 2X improvement even going to a core i3. In any case, there have to be solution to improve IPC that go beyond some circuit optimization, and HSA seems promising. We'll all have to gain if it happens: it would be nice to have again some competition non the CPU side.
