GTS450
原来是NV给的架构图比较简化导致结果不同,三个MC跟两个MC,反正是一个残的三个中用两个,用核心编号区分(KA之类),简化的图就留对称两边的作为完好的MC来画,下面MC没了
If you recall GF104, it set itself up nicely to be cut-down for GF106. With 384 CUDA cores spread over 2 GPCs and 4 sets of ROPs & memory controllers, half of a GF104 and what presumably would be a GF106 was easy to see. Instead what we’re getting is a bit of a curveball, as GF106 is a bit more than half of a GF104.
But like GF104, GF106 won’t immediately be seen in its full form. NVIDIA is launching their desktop GF106 cards with 1 of the 3 sets of memory controller/ROP pairs disabled. As a result GTS 450 as we know it today is going to be a 192 CUDA core part, but using a 128bit memory bus with 256KB of L2 cache and 16 ROPs. For the time being the only product that’s been announced that will use a full GF106 GPU is the GeForce GT 460M, which will be available in a 192bit configuration with all 192 CUDA cores enabled.
