That is what I was refering to yes, In some ways I expect the 7600 Go will be more well rounded with more TMU's and ROP's but if I were to guess lower pixel shader performance.
Turbocache is similar to Hypermemory, but Nvidia has for the most part only implemented on lower end parts as a substitue for physical ram, and then equiped the part with 16 or 32 megs of ram, usualy on a very small memory bus, I belive some TC parts are 32 bit memory interface. I also heard that Nvidia intends to sell cards with no physical memory using Turbocache in the future, we can only hope that is not true.
Ati has parts like the X1600 Mobility using Hyper memory. To augment their performance slightly. And their normal lower end parts like the X300 geting a bit more of a boost in performance. And AFAIK have not designed any super crippled 32 bit memory interface parts that use Hypermemory for life support.
