NVIDIA GeForce GTX 980 Ti Core Configuration Revealed
 

It looks like NVIDIA's GTX 980 Ti launch, which is imminent, won't be a repeat of the GTX 780 Ti, in that it won't be faster than the TITAN product at the time of launch. According to Korean tech publication HWBattle, the GTX 980 Ti will feature fewer CUDA cores than the GeForce GTX TITAN-X, at 2,816. NVIDIA gets that count by disabling 2 of the 24 SMM (streaming multiprocessor Maxwell) units on the GM200 silicon. The texture memory unit (TMU) count will be proportionately lower, at 176 (compared to 192 on the GTX TITAN-X). The ASIC bears the model number GM200-310, according to older reports.

We can't take a call on the ROP count and L3 cache amount. Normally we would deduce that it has a full complement of 96 ROPs, but given that Maxwell allows SKU designers to disable components in a way they previously couldn't, it's possible that the GTX 980 Ti could have a different ROP count than the GTX TITAN-X, just as the GTX 970 has a lower "effective" ROP count at 56, compared to the GTX 980, despite the same memory bus width. We know from other reports, that the GTX 980 Ti will feature 6 GB of memory. The TDP is a very arbitrary number, and 250W shouldn't surprise us. What also wouldn't surprise us is NVIDIA reusing the PCB and NVTTM (NVIDIA Time-to-Market) cooler design from the GTX TITAN-X (and several older SKUs). NVIDIA could allow its AIC (add-in- card) partners to come up with custom board designs from day-one.
