GK104 (GTX 680) Has 17% Higher Compute Power Than Tahiti (HD7970): Report
A report by 3DCenter.org, which takes into account the specifications of NVIDIA's GK104 GPU, based on clock-speed and specs. leak estimated its shader compute power to be 17% higher than that of AMD's Tahiti in its Radeon HD 7970 avatar (4.46 TFLOPs single-precision floating point). Based on the said specifications, the report also hypothesized things such as memory bandwidth, ROP performance, and texture performance; and compared it to those of the Radeon HD 7970 and Radeon HD 7950.

Red: Bandwidth
Yellow: ROP-Performance
Blue: Texture Performance
Green: Computational efficiency
All according to google translate.
I'd be interested to see how things roll out, I haven't ruled out an NV gpu.
walk intoestimate power draw.1) it will not overclock much more then stock.
2) retailers will only get like 10x for sale at time. ( hard 2 find & wont force the price of the 7970s down)
3) by the time it is out, all the "juiced" 7970 (Lightnings / Toxics ) will be out.
This is what he says:
"GK104 will be 680.
Seeing some benchmarks show 7970 in the lead, mostly in tessellated situations there, other "normal" synthetic 3D benchmarks and gaming benchmarks show 680 faster. Driver advancements still happening as well for 680."
Approx. 7950 performance with a good factory overclock.
But better compute.
Slots right into the performance segment where the 560Ti was, in relation to the 6950 and 6970.
If it's going to be called the 680, then they can't be using the same numbering/naming scheme as the last two generations. Looks to me like a multiple model 680 line is coming, or not, depending on what AMD does.
That would be my surmise.
Btranr whats with the title? YOu should've said: 'GTX680 looks crap compared with 7970.' :D
