BlueFalcon said: When someone lists out full specs, they list the total # of ROPs and TMUs a GPU has. Notice how they listed 18 CUs for the specs but then listed 18 TMUs. That's confusing and is not how people list GPU specs. Think about it, using the same logic you described, if someone listed HD7970 as a 32 CUs, 32 ROP, 128 TMU card ==> HD7970 would suddenly become a 128 ROP, 512 TMU part... |
ROPs are not in CU but each CU have 4 TMU in GCN arch... HD 7970 have 32 CUs, 128 TMUs (32x4) and 32 ROPs (not related to CU).
So Orbis.
18 CUs
72 TMUs (or 32 TMU backends... each backends have 4 TMUs)
32 ROPs (or 8 ROPs backends... echa backends have 4 ROPs)
That's how the GCN arch works... there is no other way to get the numbers.
