Review and testing NVIDIA GeForce GTX TITAN X

Review and testing NVIDIA GeForce GTX TITAN X

Processor GM200 – «big Maxwell» – is 8 billion transistors operating at frequencies above 1 GHz. No wonder when such data that compare the performance of TITAN X with any other graphics accelerators is described exactly as in the title. But the price until the last moment remains a mystery

The emergence of large-scale GPU architecture-based Maxwell was inevitable, the only question is when it will happen and in what form.In the end justified the assumption that the GM200 go the way of its counterpart from the family Kepler – GK110, debuted in the accelerator under the brand TITAN.

Time testing a new video card, this time there were very few, so the review will be compressed. Discarding the optional argument, let us straight to the point. Architecture Maxwell, compared with Kepler, is characterized by simplified and optimized the structure of streaming multiprocessors (SMM), which made it possible to drastically reduce the area of SMM, retaining 90% of the previous performance. In addition, GM200 belongs to the second iteration architecture Maxwell, as well as previously released chips GM204 (GeForce GTX 970/980) and GM206 (GeForce GTX 960). And consequently, has a more productive geometric engine PolyMorph Engine 3.0 and support at the level of “iron” some computing functions that are likely to enter the new feature level Direct3D 12, and the need for hardware acceleration technology for global reporting VXGI, developed by NVIDIA. For a more detailed description of the architecture Maxwell first and second generation reader is referred to the review GeForce GTX 750 Ti and GeForce GTX 980 .

Qualitatively GM200 graphics processor and a lower GPU lineup did not differ from each other, except that only the GM206 has a dedicated unit decode video compressed standard H.265 (HEVC). Purely quantitative differences. GM200 includes an unprecedented number of transistors – 8,000,000,000, so the computational units therein and a half to two times more than GM204 (depending on what is considered). In addition, back in operation 384-bit memory bus. Compared with the chip GK110 new flagship GPU is not as scary powerful, but, for example, the number of ROP here twice, making GM200 perfectly prepared to 4K resolution.

In terms of support for double precision calculations GM200 is no different from GM204. Each SMX has only four cores CUDA, compatible with FP64, so the aggregate performance under such a load is 1/32 of the FP32.

Specifications, Price

In the TITAN X uses the most powerful version of the kernel GM200 with a full range of active computing units. Basic GPU frequency is 1000 MHz, Boost Clock – 1076 MHz. Memory runs on a standard for products based on the frequency of 7012 MHz Maxwell. But the unprecedented volume for playing cards – 12 GB (a TITAN X – is primarily a gaming card, at least until the GM200 in the main, “license” line GeForce).

Recommended retail prices for TITAN X were announced in the last hours before you post a review. For the US market set the price at $ 999 – the same as at the time was worth the first TITAN based on GK110.

Design

From the very first “Titan» NVIDIA uses a top-level card, with some variations, the same cooling system. TITAN X stands out among his predecessors only absolutely black body (only two inserts on the sides remained unstained).

The back plate, which as an experiment equipped GeForce GTX 980, in TITAN X again absent, despite the fact that on the reverse side of the board of the memory chips soldered. Although chips GDDR5 additional cooling, in general, is not required.

But back to the vapor chamber cooler, which GTX 980 has been replaced by a simpler version.

The video card has three connectors DisplayPort and one piece – HDMI and Dual-Link DVI-I.

PCB design, which is not surprising, is associated with a series of video cards on the chip GK110. Voltage converter is constructed according to the scheme 6 + 2 (the number of phases for the power of the GPU and memory chips, respectively). Power is supplied through one and one six-Eight-connector. But the power controller GPU ON Semiconductor NCP81174 we see here the first time.

24 memory chips SK hynix H5GQ4H24MFR-R2C with regular frequency of 7 GHz located on both sides of the board.
