Disappointing :/

So, yes, if you're looking for the absolute best single-threaded gaming experience currently available on an AMD processor, Kaveri's an OK choice, but it may be less futureproof unless HSA takes off in a big way, seeing as how you're basically buying an i3 with two additional integer cores.

Honestly, I hope AMD releases an GPUless Athlon version of Kav; that might make it a bit more palatable.

While it can't be argued that games are becoming more multi threaded, it's not like games require more than 4 cores at this point in time. But if HSA does take off, then the 7850K will basically be a 12 core cpu in most applications (8 gpu cores + 4 cpu cores). That's the thing with AMD, they're just ahead of their time lately. I have little doubt that HSA will be widely adopted but time will tell. Especially considering how versatile it can be. I found this to be pretty interesting AMD Kaveri Features HSA Co-Processing With Discrete GPUs. Scroll down a little to see what I'm referring to.

So "Other Kaveri Guy" and I (as well as a lot of the review sites) may have to rebench everything soon. As in by the weekend.

Just saying.

Reminds me of HD7900 series launch tongue.gif

That jpeg decoder improvement and video improvement should come in real handy.

According to Tom's Hardware the Dual Graphics has some issues depending on the title:

Actually is should be better as the gpus are more evenly matched to one another.

Not AMD's naming so how am I wrong we didn't know Bonair was a refined arch for sure until AMD confirmed it they however never named it.
Not a reading comprehension at all I stated in various posts that they were by AMD.

Can't handle that the R7 240 + A8-7600 are very likely to match or beat a rig with a 7770 according to AMD?
Yeah I'm talking A8-7600 I just needed that AMD picture so I could give an indication of the gains that hybrid CF could bring.
120 + 70 is significantly less and anyone in their right mind would take the quad core Kaveri over the i3 since multitasking on an i3 actually doesn't go that well when you clog the cores even though the overal performance is not far apart. (in floating point using applications)

I agree hybrid CF has to prove itself on all fronts just saying that this route seems to be the best way to cheap performance and it would be ludicrous if AMD didn't exploit it this time around now they actually have the new tech in Kaveri.

I'm just going to post these graphs and make the point of why hybrid crossfire is problematic.






If that's not an issue for you, then fine I understand the value. My situation is that micro stutter causes migraines something fierce.

47 FPS on high >>>>> 41.4 FPS on Medium. The 7750 far exceeds the performance of the hybrid crossfire R7 240 + A8-7600 and you still think that the superior 7770 can be matched?
Warning: Spoiler! (Click to show)

Your arguments have no factual basis...
/end
Comparing framerates from different sites which have different ways of benching doesn't prove anything.
But Tom's review confirmed some of my fears that GCN matching didn't eliminate the frame time problem as a whole however it seems to be way better and actually usable compared to previous gens it remains to be seen how well the new driver will do on this.

Skyrim is known for its frame time variance issues, and we've seen other dual-GPU configurations behave strangely in the game.
You're right it has some problems in Skyrim but the other 2 look promising let's see what the new drivers bring shall we.

I am only stating the obvious. That you can't take the framerates produced by a 3770k/7750 combo and extrapolate them to an Athlon 750k/7750k combo and then proceed to claim this second combo is faster than a A8 7600+R7 240. If you want to evaluate what is faster, iGPU from A8 7600+r7 240 or 7750 solo, you bench them on the same A8 (or a steamroller athlon when they are available). If you want to compare gaming ability of DG vs 7750 based on price, you bench A8 7600+R7 240 vs Piledriver Athlon+7750.

if you want to see the performance increase check out http://www.phoronix.com/scan.php?page=article&item=amd_kaveri_7850k&num=1
the have freshly compiled benchmarks with march:native flags, so the latest steamroller fixes to gcc can be applied to the program.
