If FP64 performance is truly important to you, Nvidia would likely suggest one of its Tesla boards.▓Ɔ Ԁ ▓ S ▓ ₱▓Ɇ▓ c ▓ s ▓ : i 7 6 ʇɥפᴉƎ 0 0 K ( 4. Incidentally, an upcoming Quadro card based on the same GPU shares this fate. In fact, so much is carried over that double-precision math is still specified at 1/32 the rate of FP32, even though GM200 is the Maxwell family’s big daddy.
The other architectural elements are similar though each SMM is broken up into four blocks, with their own instruction buffer, warp scheduler and pair of dispatch units. Like the SMMs found in GM204, GM200 exposes 96KB of shared memory and 48KB of texture/L1 cache, doubling what it had in the GeForce GTX 750 Ti’s GM107. Eight texture units per SMM add up to 192-with a base core clock rate of 1000MHz, that’s 192 GTex/s (the original GeForce GTX Titan was rated at 188, despite its higher texture unit count). Multiply out the 128 CUDA cores per SMM and you get GeForce GTX Titan X’s total of 3072. And with four Streaming Multiprocessors per GPC, that adds up to 24 SMMs across the GPU. Instead of GM204’s four Graphics Processing Clusters, you get six. Like the GeForce GTX 980 and 970 we were introduced to last September, GM200 is based on Nvidia’s efficient Maxwell architecture.
In short, the company says it sought to increase utilization of the SMM by reconfiguring its resources.
