Why would that be an issue? That's basically what ATI is doing with RV770 to RV870 (doubling SPs, ROPs, TMUs, etc...).Originally Posted by saaya
But nvidia will go through a much more significant change as the SPs are now MIMD as opposed to SIMD.

one could argue todays gpu's are mimd. 64 cores is what i am waiting for.
No you can't. Each SP on all cards bar G300 are SIMD only.

but MIMD only good for GPGPU ?
When AMD had 64-bit and Intel had only 32-bit, they tried to tell the world there was no need for 64-bit. Until they got 64-bit.
When AMD had IMC and Intel had FSB, they told the world "there is plenty of life left in the FSB" (actual quote, and yes, they had *math* to show it had more bandwidth). Until they got an IMC.
When AMD had dual core and Intel had single core, they told the world that consumers don't need multi core. Until they got dual core.
When intel was using MCM, they said it was a better solution than native dies. Until they got native dies. (To be fair, we knocked *unconnected* MCM, and still do, we never knocked MCM as a technology, so hold your flames.)by John Fruehe
mimd good for everything. especially raytracing and anything branch heavy.but MIMD only good for GPGPU ?
