post #261 of 442
this thread has been fun and very entertaining but now on to more flaming matters on other threads.

for example nVidia has done it again and FAILED but using 6K mem speeds on the GTX 760.
so GTX 670 runners should feel safe..

cheers.

Kepler has a 2/3 performance/oc% while the 7970 is closer to 3/4-5/6

No it isn't. What you wrote makes no sense. Why just randomly choose 680/770 to compare it with 7970 ? Why not compare 7970 with 780 ?
I guess then reverse would be true, and you could say that clock for clock kepler architecture is stronger then GCN, because at the same clock 780 will be faster.

What I am trying to say is, if we really want to compare we would either need radeon card with around 1500 Stream Processors to compare it to 770/780 or nvidia card with around 2000 Cuda Cores to compare it to 7970.
As far as I know, neither of these card configurations exist, so we can't really compare clock for clock, only guess based on the data we have, and my guess is that architectures are actually pretty close to each other when using the same number of stream/cuda cores.

Will see if those specs for HD 8970 are true you will get a clear idea which is faster as architecture.

If we want to compare the architecture fairly, it should be 7870 vs 670 clock for clock, because these cards are most alike hadware wise, or maybe 7950 vs 770, but even then its a little bit in AMD's favor.

Comparing 7970 with 770 is really out of question, when talking about clock for clock perfomance

I have wrote NUMEROUS posts above that better explain my reasoning. Please read my other posts. Stream processors/shader cores counts have nothing to do with performance gained/oc%.

All my other posts the past few pages will tell you that and the explanation of how gcn has a better ratio (listed above).

So Kepler is more powerfully core for core but has a lower ratio of performance gainer/oc% then GCB, about 2/3 vs 3/4.

The shader core performance is one small tiny aspect of an architecture. Please read above.

If I am understanding your right, you are talking about gaining more fps for the same amount of overclock on AMD cards ?
If so, my point still stands, of course you are going to gain more fps on 7970 because it has more stream processors. Its simply logic really.

If you really want to compare architectures, and you really want to use 7970 card in the comparision, then the most accurate way is to compare it to 780, not 770

nononono you are not listening. Not at all what i said. Please look at my earlier posts:

If we had 1 gcn core and 1 kepler core, the one kepler core would be faster at the same exact clock speed, probably by about 15-20%. We know this because it takes less shaders on kepler then gcn to hit the same performance, but does so at ~5-10% clock increase. Now, if i were to overclock these individual shaders, I would see a ~2/3 ratio for kepler and ~3/4 for GCN. Doesn't matter i there are 10 kepler cores and 1 GCN core, the ratios do not change as the ratio is completely independent of shader count. The ratio is dependent on the performance per clock achieved from that architecture. So 10fps stock on 1 kepler shader with a 30% overclock will net me 12fps. if we take GCN at a 15% disadvantage per shader, so 8.5 fps, a 30% oc nets us ~10.41 fps. So, as you see, the GCN shader is weaker, but gains more out of the overclock regardless of how many shaders there are.

talking kepler, 100 shaders getting 100 fps, oc by 30%, will net you 120fps. 1000 shaders running 100fps with a 30% oc, will still net 120 fps. Just because you have more shaders does not mean you benefit more from an overclock in relation to its own hardware performance. Percentages stay constant because it is working with the same shader count for your specific chip and is defined by that specific architectures ability to turn that clock increase into raw performance.
