AMDâ€™s first 40nm GPU RV740 has been pretty hot, but its rival NVIDIA seems to be quite low-key on this. According to Beyond3d, NVIDIA is preparing its first 40nm product - GT216.
As we know, GT216 will feature 192-bit memory interface and 768MB capacity. It adopts GDDR3, working at 1.2GHz (2.4GHz data rate). Probably there will be a 384MB version of GT216. No words yet on the number of stream processors.
Well, letâ€™s suppose RV740 does have 640 stream processors, according to the proportional relation between number of SPs of RV740/RV770, we can reckon that GT216 might feature 168SPs and 56TMUs. (The original text says GT216 will equip 160SP/32TMU, but considering the structure of GT200, 160SPs sounds impossible. GT200 contains 10 groups of TPC, and each TPC has 24 SPs. For instance, GT280 has 10 groups of TPC, GT260-192 has 8 groups, GT216-216 has 9 and GT216 might have 7).
40nm product is something great to expect. Both RV740 and GT216 are highly cost effective. We will continue to follow the next round of mainstream GPU battle.
