| Viper1 said: Any rumor with an HD 79xx based GPU can be thrown in the trash as the author obviously made it up. An HD 79xx GPU is far too big (die size), too hot (200+ watts) and too expensive to even be considered. A rumor is one thing but an HD 79xx rumor is just someone trying to get his to his website. |
The rumour didn't actually say a 79XX GPU though, It said "AMD R10x series (presumably the source is from before AMD dropped the R*** naming for graphics cores) GPU @ 800 MHz (Tahiti) 1.84 TFlops and 18 Compute Units" Superchuck just assumed that Tahiti referred to the HD 79XX series GPUs. But the HD 7950 which is at 800MHz is 2.8 TFlops and 28 Compute Units (A compute unit for GCN is 64 Stream processors + a scalar coprocessor) which is just a 7970 downclocked with 4 Compute Units disabled for yeilds.
It would seem to me that while the rumoured GPU shares a codename with the high end 79XX GPUs it is not the same die at all and is actually clearly much smaller. It's likely closer to a Pitcairn GPU, and probably a bit smaller than that as the 7870 has 20 compute units.
