NVIDIA's new single-chip flagship SKU makes full use of the GT200 core, and thus provides a full complement of 240 Thread Processors coupled with 32 ROPs, and utilising a 512-bit memory bus together with 1GB of GDDR3 memory. Compared to a reference GeForce GTX 280 which boasts a core clock speed of 602MHz, with a shader clock of 1296MHz and 1GB of GDDR3 memory clocked at 1107MHz, the die shrink to 55 nanometre has allowed NVIDIA to raise reference clock speeds quite considerably for the GeForce GTX 285. Therefore, this time around we find ourselves able to enjoy a 648MHz core clock coupled to a 1476MHz shader core, while this board once again features 1GB of GDDR3 RAM, this time clocked at 1242MHz.
