hint: 192bit memory interface
Spoiler
It uses similar memory configuration as the GTX 550 Ti:
Quote:
nVidia did some modifications in the memory controller for the GTX 550 Ti, in such a way that it has three 64bit memory controllers, and each controller is controlling 2 32bit memory chips. 4 of the memory chips are 128MB in size while the remaining 2 are 256MB in size totaling 1024MB of memory at 192bit. The Raster Operators (ROP) are also tied to the memory chips, and each chip has 4 ROPs in it so in simple terms:
Note: GTX 550 Ti has 6 memory chips
Memory Controller 1 - 64bit - 128MB 32bit memory w/4 ROPs + 128MB 32bit memory w/4 ROPs
Memory Controller 2 - 64bit - 128MB 32bit memory w/4 ROPs + 128MB 32bit memory w/4 ROPs
Memory Controller 3 - 64bit - 256MB 32bit memory w/4 ROPs + 256MB 32bit memory w/4 ROPs
Total of - 192bit 1024MB memory w/ 24ROPs
In terms of memory controller, its really different from GTS 450 since it had to balance the load on the odd memory configuration, and thats up to the drivers.
