Power is delivered courtesy of two power connectors, one being six-pin, the other eight-pin. Compared to the 12 incher that is the Radeon R9 295X2, the Titan X presents much fewer space obstacles for system builders. The card itself retains the same 10.5 inch length seen with other high end graphics cards, and swallows up two slots in your case, meaning it should fit inside even smaller Mini-ITX systems without too much of an issue. One change to the cooler is the sexy all-black finish, with the Titan brand name emblazoned on one end. This is used to cool the copper vapour chamber that extracts heat from the GPU, and as expected it’s relatively quiet compared to noisier cards, though an audible hum is to be expected during heavy usage. At its heart is the same blower-style fan that grabs air from inside your case, and blows it out the rear of the PCI slots. It’s dusted off the trusty reference cooler design for use on the Titan X, adopting the exact same heatsink and fan combination as the GTX 980. It simply wouldn’t have been possible to build such a large chip if Maxwell’s design wasn’t inherently energy efficient.Due to the fact that the GPU doesn’t double as a room heater, NVIDIA hasn’t had to develop a new cooler for the Titan X.
Compare this to AMD’s R9 290X, which has a TDP of 290W, and we can see that NVIDIA’s attention to energy consumption has really paid off. They’re still built using the trusted 28 nanometre process that NVIDIA has been using for several years now, yet thanks to Maxwell’s excellent energy efficiency, the GPU has a TDP of just 250W.
TITAN X HAS FP64 SERIES
In fact, Titan X supports DirectX 12.1, a feature that is also found on the latest GTX 9XX series of cards.The huge increase in complexity sees the GM200 using an incredible eight billion transistors in its construction, a huge increase on the 5.2 billion used in the GM204. With DirectX 12 due in the near future, NVIDIA has ensured the Titan X is fully compliant with this exciting new API. With one of these cards in place, even GTAV won’t be able to fill its memory buffer, no matter how high you crank the resolution and detail. The GDDR5 memory is still clocked at 7GHz, the same as the GTX 980, but NVIDIA has tripled the amount of onboard memory, up from 4GB on the GTX 980 to an incredible 12GB on the Titan X. The Boost Clock speed – the frequency the GPU increases to when under load – has also dropped, down to 1075MHz from the GTX 980’s 1216MHz.Feeding such a powerful GPU requires some serious memory bandwidth, and NVIDIA has increased the memory bus width to 384-bits, up from the 256-bit bus of the GTX 980. It’s no wonder that it ships at a slightly slower clockspeed than the GTX 980, with a base speed of 1000MHz, compared to the GTX 980’s 1126MHz. As a result, the overall size of the GPU has increased by just under 50%, making this a brute of a chip, measuring 601 square millimetres. The texture units have had a similar increase, rising from 128 to 192, while the ROPs (Render Output Unit) have also increased by 50%, up to 96 from the GM204’s 64. NVIDIA’s CUDA Cores are the units that handle the heavy lifting inside Maxwell, and the GM200 now ships with 3072 of these, a 50% increase on the 2048 found within the GM204. They’ve basically taken the GM204 chip found at the heart of the GTX 980, and increased every internal section by 50%, creating the new GM200 chip that powers the Titan X. Like all of NVIDIA’s existing graphics cards, the Titan X is based on its Maxwell 2 architecture. Whether or not it’s worth the audacious price tag is another question entirely. Unlike previous Titans, this isn’t just a slightly enhanced version of its flagship GPU NVIDIA has gone the whole hog and developed a product t hat is a huge step up from the GTX 980. Go big, or go home – and NVIDIA’s going very big!Just when we thought NVIDIA couldn’t release a more expensive product, along comes its latest premium product, the Titan X.
