AMD A10-7850K and A10-7700K Kaveri Leaks Including Initial GPU Benchmarks

The launch and subsequent availability of Kaveri is scheduled for the CES time frame. The APU unites Steamroller x86 cores with several Graphics Core Next (GCN) cores. The high-end offering, the A10-7850K, is capable of 856 GFLOPs of compute power (most of which is of course from the GPU).

We now know about two SKUs: the A10-7850K and the A10-7700K. Both parts are quite similar except that the higher model is given a 200 MHz CPU bump, 3.8 GHz to 4.0 Ghz, and 33% more GPU units, 6 to 8.

But how does this compare? The original source (prohardver.hu) claims that Kaveri will achieve an average 28 FPS in Crysis 3 on low at 1680x1050; this is a 12% increase over Richland. It also achieved an average 53 FPS with Sleeping Dogs on Medium which is 26% more than Richland.

These are healthy increases over the previous generation but do not even account for HSA advantages. I am really curious what will happen if integrated graphics become accessible enough that game developers decide to target it for general compute applications. The reduction in latency (semi-wasted time bouncing memory between compute devices) might open this architecture to where it can really shine.

We will do our best to keep you up to date on this part especially when it launches at CES.

Do you know if we will be able to Xfire them with higher gpus yet, say like a 7770 or 260?

Since Richland cross-fires with 7750, it is safe to assume that Kavery will as well cross-fire.

since when does richland cross fire with the 7750? According to every thing I have heard anything higher than a 6670 disables the apu's video cores. Sure you can conect the 7750 to your motherboard crossfire port, but you will only get the proformance of the discrete card.

There are numerous examples of people successfully hybrid crossfiring the 7750 with the A10-6800(Richland) (See You-Tube). It is not officially supported by AMD, but it works!

I think 30% is to be expected due to the jump in shader processors: 384 VLIW4 to 512GCN.
If the increase is lower than 30% then probably there are other bottlenecks (like memory badwidth or the CPU cores).

It can also be that the drivers are very immature. Looks like AMD may just serve yet another anticlimactic product.

wonder if AMD gonna compare it to an nvidia gt630 again?

I can't wait to see it in action. I'm planning to build a small game rig with that APU inside, but I'm wonder if 8 GCN will be enough for decent play. I mean why AMD couldn't put 12 or 10 GCN, like they promised early this year?

Oh, let me think, for the same reason it's down clocked vs. Richland, namely, staying at 95W TDP?

Come on, dont tell me that AMD is trying to be super power efficient right now. Especially when you putting massive iGPU in architecture. Who cares about 30W of power more, if you will get a better performance.

With the GPU being faster, how will the memory bottleneck impact it as it was significantly impacting older integrated GPU's?

Yes How wide is the Internal Bus that is shared between CPU and GPU. as well as the external bus/max memory speed! uHMA should help with the memory/bandwidth issues, and will there be a benchmark to measure total aggregate memory transfer/bandwidth used vs total available bandwidth per unit time, or other measures of uHMA efficiency?

You guys realize that in the source, it states that they use A10-6800K, which is richland.

You all recognized that they are only trying to simulate the performance of the Kaveri APU with an Radeon HD 7750 and a A10-6800K?

Not only this, but with under-performing memory for a A10-6800K.

With the right simulation software, that is available to all CPU designers/manufacturers it is possable farely accurately test designs well before they are committed to silicon, and yes trying to simulate an entirely new design, from a previous generation SKU's performence needs a Big * and capital letters in the footnotes, short of having an actual engineering sample at hand. The big uncertainty for everyone is always the fabrication process and yields, and the inevitable binning that happens with every new fab node process, new/recurring driver headaches, and other business concerns *.

* THIS ALSO INCLUDES THE CORPORATE BEAN COUNTERS, THAT DO NOT WANT SKUs COMPETING ACROSS PRODUCT LINES.

hi I have the a10-7700k apu I was wondering if you can crossfire it with a 7750 graphics card
