GM200 GPU, 3072 CUDA cores and US $999 price tag
After teasing it during Game Developers Conference 2015, Nvidia's CEO has now officially announced the new Geforce GTX Titan X graphics card.
Based on Nvidia's new 28nm GM200 Maxwell GPU with 8 billion transistors, the GTX Titan X graphics card packs 3072 CUDA cores, 192 TMUs and 96 ROPs as well as 3MB of L2 cache and 12GB of GDDR5 memory paired up with a 384-bit memory interface. Working at 1000MHz base GPU and 1075MHz GPU Boost clocks with 12GB of memory clocked at 7.0GHz, the new Titan X has a 250W TDP, something that was expected from a Titan series graphics card.
What makes the GTX Titan X different from the previously available Kepler-based GTX Titan Black graphics card, is that GTX Titan X is more of a consumer graphics cards and can be considered as the GTX 980 on steroids rather than a graphics card with impressive double-precision compute performance.
According to Nvidia, the GTX Titan X will have a single-precision compute performance of 7 TFLOPS, while double-precision compute performance will be 0.2TFLOPS, showing that the GTX Titan X has 128 FP32 CUDA cores per SMM and just 4 FP64 ALUs per SMM, which leads to a standard 1/32 native FP64 rate. This also shows that GTX Titan X is more focused on FP32 compute performance rather than FP64 which will most likely be reserved for Quadro and Tesla graphics cards.
As far as the rest of Titan X details are concerned, we are looking at a same blower-style cooler seen on a lot of recent Nvidia Geforce graphics cards, including aluminum shroud and Titan logo, same PCB with 6+2-phase VRM and lack of backplate, something that was done on previous Titan graphics cards as well.
The GTX Titan X needs 6+8-pin PCI-Express power connectors and comes with the same display I/O configuration as the GTX 980, including one DL-DVI-I, three DisplayPort 1.2 and single HDMI 2.0 input, limiting it to a total of four displays at the same time.
Nvidia also decided to keep the same US $999 price tag, which is the same price of the original Titan. While it might sound a bit steep, bear in mind that this is the fastest single-GPU graphics card that money can buy and it does not come as a surprise that Nvidia wants to cash in on this fact.
According to a couple of reviews that are already posted online, we are indeed looking at the fastest single-GPU graphics card ever made with significant performance improvements compared to the GM204 based GTX 980 graphics card but since it lacks double-precision compute performance, the price might be just a bit too high.
