AMD A10-7850K And A8-7600: Kaveri Gives Us A Taste Of HSA
We've spent the days following CES benchmarking two of AMD's new Kaveri-based APUs. Do the Steamroller x86 architecture, GCN graphics design, and HSA-oriented features impress, or do they come up short against Intel's value-oriented Haswell-based parts?
Gaming: The Elder Scrolls V: Skyrim And World Of Warcraft
We tend to think of Skyrim as a graphics pushover. But at 1920x1080, it keeps everything we’re testing under an average of 40 FPS.
First things first—Intel’s HD Graphics 4600 is wholly incapable on its own. The company really needs to enable its GT3/GT3e configuration on the desktop at a reasonable price.
From there, we see the 45 W A8-7600 smoke the 45 W -6500T, hammering home AMD’s emphasis on GPU performance at lower power ceilings. The same is true to a lesser degree as the 65 W -7600 configuration outperforms the 100 W A10-6800K in our Skyrim benchmark. Finally, the -7850K is around 19% quicker than the fastest Richland-based APU—still pretty darned good.
World of Warcraft also gets derided as mainstream fodder, though it drags down our integrated graphics engines as well (even at the mid-range Good quality preset).
Intel’s more capable x86 cores allow the Core i5 and i3 to make up some ground against AMD’s APUs, but not enough for playable performance at 1920x1080.
The A8-7600 manually set to 45 W does get us pretty close though, simultaneously embarrassing the 45 W A8-6500T. Stepping up through the APU line-up yields small gains, culminating in the 95 W -7850K’s victory over A10-6800K by just 7%--likely due to the loss of clock rate on the host processing side. Even still, Kaveri is quite clearly a win performance-wise. Is it worth an extra $30+, plus a new motherboard? Probably not. Could we see some really cool mobile gaming platforms at more affordable price points than anything Intel has? It’d certainly seem so.

Someone Somewhere Yeah, almost all the diagrams refer to the 4760K.Reply
Given that AM3+ looks like it's done, it would have been nice to see a 6-core chip. Still, one of these may end up in my next laptop. -
spp85 A10-7850k is slower than A10-6800K ?? WTF. Its all hype than actual performance to the table. Even on OpenCL GPU accelerated apps doesn't have any advantage with A10-7850k over i5 or sometimes i3 CPUs. Hopeless is what I feel about AMD CPUs.Reply -

I got the opposite impression. Which graph are you looking at? -
Jaroslav Jandek Thank you for the article (especially the power consumption measurements), Chris. It is definitely an improvement over Richland but kind of boring (disappointingly expectable).Reply
I really like where AMD is going (HSA, GCN and TrueAudio).Too bad the manufacturing process of GlobalFoundries just can't match Intel's.
Also, it would be interesting to see the new Bay Trail Pentium or Celeron CPUs (whichever is closer in performance) in the Efficiency graphs. -
Someone Somewhere I'm fairly sure that this is on TSMC's 28nm node. GlobalFoundries can't do that yet; this is on the same process used for AMD GPUs currently.Reply -

28nm SHP from GlobalFoundries. AMD bought over $1 billion worth of wafers from them in december...12454280 said:I'm fairly sure that this is on TSMC's 28nm node. GlobalFoundries can't do that yet; this is on the same process used for AMD GPUs currently.
I guess you have been reading the articles from a year ago about AMD still using TSMC despite promises of GlobalFoundries' new 28nm SHP process. -
jacobian I don't really believe into the whole HSA smoke-screen. By the time HSA-enabled apps take off, you will be ready to upgrade from your CPU again. The one terrible truth that stands out right now is that at current prices, the flagship Kaveri A10 doesn't make any sense whatsoever. Kaveri A8? Maybe. Richland A10-6790K? Perhaps. But the Kaveri A10 at $180 is a just a joke, specially after all that hype.Reply -
Someone Somewhere CPUs are usually released at ridiculous prices, and come down over a month or two.Reply
