NVIDIA GeForce GTX TITAN X Launched (GM200 and 12GB VRAM)

NVIDIA has officially introduced during the GTC 2015 keynote the new super gaming graphics card: the GeForce GTX TITAN X. This new beast is based on the second generation of Maxwell GPU but this time it’s the big version: the GM200. This big GPU comes with a whoooopping 12GB of VRAM! The price of TITAN is also big: USD $999.

The GM200 can be seen as GTX 980 GM204‘s big brother but it’s not a pure computing GPU because of the limited FP64 (double precision floating point):
– GTX TITAN X / GM200: FP64 = 1/32 FP32
– GTX TITAN / GK110: FP64 = 1/3 FP32

So if you have ton of FP64 computing needs, the previous gen GK110 TITAN (and TITAN Black) is still the right choice.

Main features of the GTX TITAN X:

• GPU: GM200 @ 1000MHz (base clock) and 1075MHz (boost clock), TSMC 28nm, 8 billion transitor
• CUDA cores: 3072
• FP64 = 1/32 FP32
• ROPs: 96
• Texture units: 192
• Memory: 12GB GDDR5 @ 7GHz effective speed (1750 MHz real speed), bus width: 384-bit
• TDP: 250W
• Power connectors: 8-pin + 6-pin
