As of today the NVIDIA Titan X is simply the fastest single GPU money can buy. Based on 3584 CUDA cores this is no wonder, yet - for apparent reasons - we're curious to find out how big the difference between the Titan X and other pixel accelerators is.






Presentation

The NVIDIA Titan X (Pascal) is currently the most expensive single-GPU graphics card available on the market. This pixel accelerator is based on the GP102-400A1 Pascal chip. As it's been with all the Titan cards before, also the Titan X (Pascal) is only available with a reference design, which means this card features the same cooler like the GTX 1080 Founders Edition but with a black paint job. Apart from that, end customers can only buy this card directly from NVIDIA's website. Furthermore there are serveral distinct system integrators globally building gaming PCs and workstations with NVIDIA Titan X (Pascal) cards. This adds a lot to the exclusivity of this particular pixel acceleartor and NVIDIA even goes to the point that one person cannot order more than two cards.

Browsing the specifications of the GP102-400A1 chip we find a whopping 3584 CUDA cores, 224 TMUs and 96 ROPs. For comparison reasons, the GTX 1080 features 2560 CUDA cores, 160 TMUs and 64 ROPs. This means that, compared to the second fastest card in the NVIDIA line-up the GP102 features significantly more CUDA cores, TMUs and ROPs. Looking at clock speeds we find a base clock set to 1'417 MHz and the boost clock is at 1'531 MHz, which in combination with the sheer number of CUDA cores is going to pack some serious punch.

As we already mentioned, the NVIDIA Titan X is a reference design card, which means there is apparently no factory sided overclocking. This card is set to work at 1418 MHz base clock and 1531 MHz boost clock, while the typical boost clock is 1809 MHz when tested with 3DMark FireStrike, which in this case is representative for almost any game. Testing the card with Furmark, which forces the lowest typical boost clock, we noticed that this particular Titan X was at least running at 1733 MHz, while the voltage was as low as 0.85v.

A quick look at the memory specs reveals, that the 12 Gigabyte GDDR5X come from Micron, have been wired to the GPU using a 384 Bit wide interface, clocking at 1251 MHz (effective 10'008 MHz) and therefore offering 480 GB/s bandwidth. Compared to a GTX 1080, which cranks out 320 GB/s the memory bandwidth has been improved pretty drastically - actually by a whopping 50 percent.
