NVIDIA GF100 & Friends speculation

Quite high clock. Wondering if Nvidia could do that without a slight voltage bump (about 50mV like the GTS 450 needed) or not. If so power draw will probably be quite high but it shouldn't be catastrophic. Otherwise it should have quite good perf/power ratio. Should definitely be competitive with HD6870.
btw why the hell did they test that in a electrical pcie 4x slot?

Probably because the card/bios isn't mature enough to be relied upon as the primary or possibly because the person didn't want to take out their main card in order to GPU-Z a card they were testing/sneaked out from somewhere.

maybe reducing idle power consumption ?
Well that should give the HD 6950 a run for its money… I sense good deals ahead!

560 is going to rock if that picture is true.

How come, there is only an extra 100mhz on memory. Should be plenty to beat a 6870, but it can only match cypress, lagging behind a 6950 with 1GB memory. All AMD need to do is sell the 6870 for 200$.

48 more SPs and a 100Mhz boost. Could add up to around 30% above 460 which would put it directly below 6950 but at $229 if Nvidia maintain the price point of the 460.
According to this chart a 30% boost to GTX460 1GB would put it at 95% of a 6950, with factory OC cards you could easily reach the 6950 stock performance with a possibly cheaper card.

But it only gets a 11% boost in memory. Combined with a 30%+ boost in shader power it averages down to... ~25%? (depending on workload ofc) That's around GTX470 level. I guess there will be some tweaks (ie. imporved z-cull from GF100b) that will make it seperate itself from the 6870/470 groups but only a few % on average...
I don't think it can compete with HD 6950 but it could get close (well the HD 6870 is close too...).
If you look at the Zotac GTX 460 AMP for instance, it has very nearly the same clocks (10Mhz less core clock, same memory clock). And this review here puts this still 10% below HD 6870: http://ht4u.net/reviews/2010/powercolor_pcs_plus_hd6870_test/index26.php - so all the GTX 560 has on top of that is the additional SM probably. That is 16% more shading power, if we assume "decent" scaling that might certainly be enough to catch the HD 6870 (would need 10%) but probably not much more - hence it would still miss about 10% for catching the HD 6950.
That is assuming there are no other chip improvements.

GTX 560 looks like it will spank Barts a new one and pressure Cayman Pro...if Nvidia retails at 239....is there even room for a 6770?
At 820mhz i guess....overclocking bits will not be a much advertised feature? Fermi seems to clock out at 850mhz give or take....without adding volt/tdp. Interesting how Nvidia balanced Fermi parts...a bigger drop in CUDA cores over their next in line GTX 570....but 100mhz more that should beat big GTX 470 part and remains 85% of GTX 570 perf? Mhz is still king/sensitive.

I dont think there will be 6890..too fast too confusing...maybe it will be the first 28nm gpu from AMD....6930 is also negative as we hear Cayman yields are quite good..6950 1GB maybe..with slower clocks like GTX460? Too confusing....
I have a feeling GTX560 will be a big success and get great reviews....it will do what AMD wanted to do with BartsXT/Cayman Pro...

A 28nm GPU in either 6800 or 6900 series would make things far too confusing.
I think 560 will be to 460 what 580 was to 480 - an extra 10-15% performance for the same thermal and power specs.
Nothing more really, but I would appreciate a speedier GDDR5 controller.
If all the rumors turn positive, I think GTX560 will be my next card for the main rig (after nearly five years of solid ATi presence).
I'm truly tired of shelling small fortunes for overpowered top-end models, not even utilizing half of the features/performance in there.
Unlike GF100, GF104 wasn't particularly bad from a power perspective, so I wouldn't expect much improvement in the performance/power area. I would expect a solid 30% performance improvement though, up to (384/336) × (820/675) = 1,389, i.e. +39%.
So I'm thinking ~HD 6950 performance for about 200W or more (160W + 25%).

Which doesn't matter to the customer as long as price / performance and features are good.
It's certainly going to affect the price they can afford to sell it for.
