Example: same exact GPU on 2 PCs (7950), one with a FX-6300 and one with a i5-4670K. Both clocked at 4.6Ghz.

Neverwinter max settings vsync off

FX-6300 average FPS: ~40
i5-4670K average FPS: ~60

It's only a handful of games that show that kind of difference though, I went from an FX-4170 to my i5 3570k (both at 4.5Ghz) with a HD7950 and proceeded to notice small differences in most games I play with the only large differences being in a handful such as Civ V or Sins of a Solar Empire. Hell, most games I play leave my CPU under 40% and GPU at >80% average...I'd definitely wager that for every game that has a large difference, there's 2-3 that either don't show it or run more than fast enough on even a Pentium.

OC-part
still 38C until maximum T? They use watercooling

So, everyone else says it's barely an improvement over Richland, and OCUK shows us a MASSIVE performance uplift over Richland?

Interesting...

Heh.... Anadtech did completely wrong benchmark - and you can see huge difference between steamroller and piledriver.

Actually there you can see, why they want to show steamroller as a bad arhitecture

if yopu look difference between i7 3770 and i7 4770 - you will notice that i7 4770 look bad/worse than i7 3770

OC UK may be a bit less biased in a positive way to AMD and actually compare clock for clock and price/price and efficiency. OC UK were the ones all over the 290(x) launch to bring it to the people which by the way is an amazing card with a extremely bad cooler.

Kaveri will be massive in laptops the efficiency surpasses that of the Iris pro 65W chips it it is considerably stronger in non FP tasks than a i3 of course the i3 has the strong FPU and the relatively good integer performance but in efficiency with the gpu in the equation Kaveri chips would still destroy it.

We have seen incredible power efficiency numbers in the sub 3,3GHz space with 4,0/4,4 consuming over twice as much.
I think that a 512SP @ 600MHz 2M/4C @ 2,0/2,5 could easily scale into the 25W space and depending on how well it scales the can even keep full parts down until the 15W space. Scaling things up is almost always more efficient that upping the clock if you are already running pretty high.

From a quick look at Povray resuts, they seem to jive with anand's on this particular bench.

We will have to wait to see difference in games.

And actually it is huge improvement, if we compare buldozer vs piledriver and piledriver vs steamroller - clock per clock smile.gif

I don't have the screencaps anymore, I did that test several months ago. This graph does a decent job of showing what I'm talking about though.



30% increase in average FPS, while being clocked much lower.

Ryude... like i said i some games you will have same speed/FPS if you OC FX to 4,3-4,5Ghz (intel 3.9GHZ) while in some games you will need 5.1-5.6GHz ...
post #669 of 1004
Total side note here but I want to address something that kind of bugs from a board that is obsessed with the latest and greatest.

APU is currently a dirty word on this board. Lets be honest here, to most of you it means midrange garbage. To a few of you it even means "Just another new guy, building a computer he doesn't understand (and/or have the money for) coming to ask us all inane questions about basic over clocking principles and fill our benchmarking threads with unimpressive scores."

I purposely bought Kaveri for this reason. I'll even admit to you all right now that I easily could have had an i7 3930K and a top of the line Intel Motherboard. I came from a 4.9 GHz FX8350 for God's sake and (currently) it is a step back from nearly all of those. Well besides removing the dreaded AMD high end discreet GPU bottleneck in older, poorly threaded games. It does that much fairly well at this point, pretty much killing the stigma of pairing a $200 CPU with a $500+ GFX card, but I digress, as my thread in the AMD CPU forum is for that madness...

Back to the point.

Too many of us have forgotten something about the original plan and idea behind these APU's. The endgame of these things isnt to destroy the high end enthusiast level chips we all come here to celebrate. It's to enchance it. To Evolve it.

Hell it's to revolutionize it.

The point is to take something that even the highest end Intel chip money can buy does marginally well and replace it with something that does it exceptionally well. The plan is to implement that change as cheaply and easily as possible. It is to get the devs and the ( no matter futile the attempts have been up till now) system building community excited about this.

Whether you or I like it or not, this is the future. If you dont believe me when I say this keep in mind that even the mighty king of x86 floating point themselves Intel, has very much admitted it with their actions, if not their words this stuff should be taken seriously.

Lemme ask you this. Do you really think Intel would go through all the trouble to start making their own ondie iGPU's for markets they already completely dominate if they didn't think this HSA idea was a serious threat and/or something they should get in on?

I bought Kaveri instead of that i7 for this reason. The entire point of 4 slightly stronger x86 cores, 8 GCN cores, and the dropping of L3 cache, the later of which caused our entire board to collectively groan when we first heard it is, and has been completely lost on us since. Even though we are the enthusiast market and therefore inherently possess a much better ability to comprehend and understand the full scope of this change and what it means. We somehow, in spite of this ability, have forgotten the chip was developed like that for a reason. It's like that so our processors can now assign workloads that a GPU can handle 500% better than a traditional CPU to that onboard GPU for minimal (if not zero) effort from the user or developer.

As such we shouldnt even be reviewing this thing yet. Give your opinion sure, benchmark it like crazy (like me), and hell, complain and scream to the heavens about it being released incomplete (lord knows I have), but don't make a final judgement yet on a chip that could change everything. Don't do that till it's had fair chance to do so and either failed at it's task, accomplished it.

As a month from now you very well might be eating your words, buried under a mountain of 15,000+ point Kaveri 3D Mark Physics scores, frantically trying to order one to Tri-Fire with three 290X's.

Can you OC kaveri iGPU (memory and core clock) and try games at 1080P?
