They don't add anything to flops count so it doesn't make much sense to count them. Well actually with G80 they did contribute theoretically though just a tiny bit (they could do mul at IIRC 1/4 rate that of the ordinary "cores", much controversy about the "missing mul"). I think with Fermi/Kepler though this was no longer possible at all since it was impossible to dispatch enough instructions simultaneously to SFUs and ordinary ALU lanes (and I don't know or can't remember if they actually still could do a mul). I suspect that's still the same with Maxwell, though I may misinterpret the shiny diagrams.
There aren't any SFUs since those functions are all integrated into ordinary ALUs. Well actually I don't know how integrated they really are but simultaneous dispatch is definitely not possible.
Counting SFUs where: In GFLOPS or reported number of ALUs?
My only explanation is that I must have typed 0.95 instead of 0.90…
There are new "PR benches" out at videocardz comparing the card to r7 260 and 260x as well as GTX 480. Anyway we should get proper reviews in a couples of hours
).Because marketing has found that most gamers don't upgrade every cycle but every two cycles so that comparison is directed to them.
Tin foil hat comment.
I am looking to replace my GTS 450 in my HTPC with one of these cards.I'm actually quite excited those cards could do great in the htpc I'm dreaming to build (/money
I think they are here
