I don't spill my beans like that :whiste: just giving some slight nudges here or there.

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.

What is Tahiti XTL. is it same ASIC with a few tweaks.or is it same ASIC with higher clocks. is Tahiti XTL > Tahiti XT ?

"Gap filler" will be misleading anyway. There is always overlapping between generations. We are in a unique position on the AMD side now since this generation would normally have been expected in Q1 2013, and there would even have been 6xxx cards around in that case. There's no "danger" in getting a 7xxx card card now since they're awesome value for the price and no matter what 9xxx deliver that is very unlikely to change.

I mean gap filler as in "98xx wont beat 79xx in performance, so 79xx will be between 98xx and 99xx series".

looks like sushi warrior is hinting at a 470 - 480 sq mm die size for Hawaii. 2:1 DP could be on the cards. though I find it unlikely.

Southern Islands already had 2 FMA SP to 1 FMA DP.

Correct me if I am wrong, but Southern Islands had the option for 1/2DP ratio, but no product/die ever used the capability.

All 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).

This doesn't include Bonaire and Oland. All the dies support 1/2 DP, it is only a driver/software limit.

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.

I'm in a similar boat, rebuilding to Haswell shortly, but going to hold onto my 7950 for a few more months until these new cards are released. There's faster cards than the 7950 out, but they don't offer enough over my 7950 to justify the expense.
