Does not exist () (yet?)
you are goddamn teasing us. :biggrin: Does HD 9970 beat Titan ?
I know ur under NDA and stuff, but can you clarify if 79xx will coexist with 9xxx series working as a gap filler between the performance of the (yet to be released) 98xx and 99xx series GPUs? Planning on buying a 7950 but all I hear is info regarding 99xx, not 98xx and their (expected to be) performance.
Tahiti is still a part of the overall plan, in one form or another (eg. Tahiti XTL is a new possible SKU). This isn't an entire, 100% new GCN2.0 lineup, this is Hawaii (+ a few kickers of GCN1.0 SKU's) and then the rest of GCN2.0 (Tonga, Iceland etc.) will roll in slowly in the future. 7950/7970 still have their own distinct spot in the lineup and I don't know of anything intended to replace them. Their value is awesome, some models on sale are unbeatable.
Southern Islands already had 2 FMA SP to 1 FMA DP.2:1 DP could be on the cards.

Correct me if I am wrong, but Southern Islands had the option for 1/2DP ratio, but no product/die ever used the capability.
http://developer.amd.com/download/AMD_Accelerated_Parallel_Processing_OpenCL_Programming_Guide.pdfAll Southern Islands GPUs have double-precision support. For Tahiti (AMD Radeon™ HD 79XX series), double precision adds run at one-half the single precision add rate. Double-precision multiplies and MAD instructions run at one quarter the floating-point rate.
The double-precision rate of Pitcairn (AMD Radeon™ HD 78XX series) and Cape Verde (AMD Radeon™ HD 77XX series) is one quarter that of Tahiti. This also affects the performance of single-precision fused multiple add (FMA).

Awesome, looking forward too it. Just bought a new rig but am holding off on the graphics card till the 9 series, I'm ready to rock and kick my 6970 to the curb.
