Machiavellian said: DIfference is one is performing 64 threads while the other is doing 32. As I stated this is what the poster draws his conclusion that the 12 SC or Shared Cores he likes to called it is actually an Array of 4 CU cores instead of just being one CU core. |
No. You are reading wrong... the memory mapping is 64bits not 64 threads and each CU have 64 threads.
VGLeaks just use wrong terms.
- as SMID is CU (in vgleak term)
- each SMID = 64 thread lockstep (Vgleak term)
- each CU : 16 Operation /cycle across 4 ALU = 64 ALU per cycle/lockstep
- in Vgleak term Thread = ALU
- in vgleak 1 Operation = 4 Thread
Edit - Fixed.
