Since the days of NVIDIA's very first DirectX 10 GPUs, NVIDIA has been using different clock domains for the shaders and the rest of the GPU (geometry domain). Over the past few generations, the shader clock has been set 2x the geometry domain (the rest of the GPU). 3DCenter.org has learned that with the next-generation "Kepler" family of GPUs, NVIDIA will do away with this "Hotclock" principle. The heavy number-crunching parts of the GPU, the CUDA cores, will run at the same clock-speed as the rest of the GPU.

same clocks? so it will now run in 2 clocks? (core and memory) and no more option to tune the 3rd clock (just liek the Radeon HD series)

I hope this comes out soon so it gives amd some competition and prices will be driven down.

Before teh release of the 8xxx series of cards by nvidia, there never used to be shader clocks. Was always just core and memory.

Teh GeForce 7 had an internal variable clocks tho, and it can be exposed in some GPU utilities (particularly RivaTuner with advanced tweaking), but yes the G80 era ushered separation of Rasterizing engine from the shader engine.

I remember unlocking the 6800gs AGP back in the day. They went by pipelines back then. :laugh:

Ah yes the pipeline unlocking was the talk back then, but there is a setting in the GeForce 7 series cards for more than just that (monitoring multiple clock domains), i forgot where i found it tho, its been so long.

Back before I got the 6800GS on AGP, I had an FX5200 and it SUCKED so hardcore. I didnt have the money to upgrade my machine then to a pci-e board back then. I wanna say it was in January or February i remember them announcing a 6800gs for AGP and I managed to get the money. I was so stoked. It was the best thing you could get your hands on for AGP. Then out came the news about unlocking the card with riva tuner. Those were the days.

Here's my specs from back in the day:
PSU: Sunbeam 450 Watt (Came with Case)
Case: Sunbeam Transformer Full Tower (Black) w/ Blue LED's
Motherboard: Gigabyte GA-K8NSC-939 F8 BIOS

Hard Drive: 3 Maxtor Drives; 1x40GB, 1x30GB, 1x300GB SATA
Video Card: BFG nVidia GeForce 6800GS OC (412/1.12) w/ 16 pipes (unlocked)
Monitor: SAMSUNG 19 inch SyncMaster 930B
Sound Card: SoundBlaster Live! 24-bit

i had a 5900XT and a 6600GT back then :D, had to flash my 6600GT to enable temp monitoring

I wonder if Kepler would still enable domain clock monitoring (and maybe even OC;ing different domains)

And there goes nvidia's performans, low shader clock can never be good, i wish to see lower core clock, higher shader clock to reduce the tdp damn you nvidia:p
If this is treu i gues we have to wait how this performs

They`ll come close +- 10%,they melted core and shader clock into one,same architecture......
In the end,the worst scenario for amd will be comparison like the 6xxx vs 5xx,just a little more step in performance gain,than the temporary gen did with previous one.

So, F@H performance is going to be about the same as the current generation? Twice as many shaders running at half the speed. Will have to see how well AMD's APP Acceleration on the 7xxx series works.

what? Did you even read. At the end of the OP it says that kepler will have signicant architectural changes. It won't be the same exact as fermi

It will be more efficient,less power consumption,better computing power and tessalation...but it wont have great impact on raw performance in just core per clock,and in the same amount of shaders. they cant do 1.5x faster at same clock,shader count with just architecture change,maybe 1.1x,but thats it. However they will make very interesting product.
Sadly they wont release it when D3, MassEff3 arrive ,and than I`ll have to buy gtx 570 or radeon 6970, 78xx or if budget allow 7950 .

Good one, theres no doubt it will be a fine series, thank god for amd & nvidia, without either one, our choices could be so much more limited and prices so much higher.
