[Various] AMD Kaveri A10-7850K (7700K, 7600) reviews - Page 12

post #111 of 1004
7600 seems to like fast memory for gaming. Honestly it could be a nice APU for a cheap build if you're planning on doing some light gaming but not enough to warrant a discrete solution. You could also use it in a smaller enclosure. Other than that Kaveri seems like a disappointment. AMD needs HSA to actually become a thing rather than just marketing talk. But like Anandtech review said, what they really need is a new arch.

If you have a Microcenter close by, here is the pricing: http://www.microcenter.com/site/products/amd_bundles.aspx

Other reviews like Anandtech used DDR3 2033Mhz and A10-7850K is barely faster than A10-6800K in gaming benchmarks

And it is much slower than HD6750. Funny that some crazy people were telling me that Kaveri is going to be as fast as HD7750 and few people even told me that it might match HD7770. THose people must be dreaming

Apples to oranges, the 6750 is combined with an i7-4770, what did you expect, seriously? And in comparison to 6800k, 7850k iGPU on that review appears 20% faster on bioshock infinite and 10-30% on Tomb RaiderSleeping dogs/CoH2- they are matched in F1 2013 and 1280x1024 tests (probably cpu bound on that res).

I'd still like to get an idea just how much the DDR3 memory interface is bottlenecking the built-in GPU. Please some site benchmark the A10-7850K with a Radeon HD 7750 GGDR5, preferably downclocked from 800 Mhz to 720 Mhz.

Also, it would be interesting to benchmark the A10-7700K with CPU clocked at 3.7 Ghz and the GPU clocked at 844 Mhz (Richland's GPU clockspeed) and see how well it would do against both the A10-6800K and the A10-7850K.

Matching richland iGPU clocks is kinda pointless since it uses an older architecture.

The same people who posted everywhere and set those unrealistic expectations are also conspicuously missing from this thread.

What I'm trying to find out with all the suggestions in my post is:

By how much is the built-in GPU on the A10-7850K bottlenecked by the DDR3 memory interface ? Surely the Anand test system with the HD 6750 is using an Intel CPU, but shouldn't the difference in GPU performance offset that ?

My theory is that AMD is using more GCN cores clocked lower in order to try make their product better than it really is, because I suspect that a 384 core GCN part clocked at Richland's 844 Mhz instead of 720 Mhz is going to yield the same kind of performance as the 512 cores running at 720 Mhz. From the benchmarks it's clearly visible in some cases that the fps hit a wall, no matter if it's the Kaveri A8 or the A10. I suspect it's a RAM bottleneck, which means it's debatable whether it's cost-effective to use 512 GCN cores at 720 Mhz over 384 cores at 844 Mhz.

Same here. I would have been on my way home from Microcenter right now otherwise.

I'm thinking MC will come down in a week or two.

** I just looked at newegg and the 7850 is now 189? rolleyes.gif
