The specifications of the NVIDIA GeForce GTX Titan X were published over at VideoCardz. As always, this is unofficial information so take it with a grain of salt but it looks credible.
The site claims the GTX Titan X has a full GM200 GPU with 3072 CUDA cores, 192 TMUs and 96 raster units. The GPU consists of 6 Graphics Processing Clusters (GPC) with 4 SMMs each, resulting in a total of 24 SMMs. The memory is wired to 6 memory controllers, each 64-bit wide, allowing 384-bit communication.
The core clockspeed is rumored to be 1002MHz, with a 1089MHz Boost and 12GB GDDR5 memory clocked at 7GHz effective.
We were told TITAN X has TDP of 250W (to be confirmed). It’s less than Radeon R9 290X, but much more than GTX 980. You will get 30-40% better performance with 85W higher consumption, is it worth it? Silly question, of course it is.
TITAN X overclocks rather easily to 1200 MHz (1280 MHz boost). The memory will run at 2000 MHz (8GHz effective), but make sure to check the reviews on Tuesday, which modules are these samples using. As far as I know, TITAN X may ship with Hynix, Samsung and Elpida memory. I will either update this post or make another if I know more.
More details are expected soon as NVIDIA's new flagship is expected to make its debut at the firm's GPU Technology Conference later this week.
