GeForce GTX 980 Ti

NVIDIA used the same cooler design for the reference version of the GeForce GTX 980 Ti graphics card as the GeForce GTX 970, GTX 980 and GTX Titan X. The green company used the same GPU for the GeForce GTX 980 Ti graphics card as in the case of the GeForce GTX Titan X-GM200. But now the GM200-310-A1 stepping is used, which is a stripped down version of the GM200. NVIDIA still manufactures its GPUs in TSMC's 28nm factories - an impressive chip considering 8 billion transistors.

Unlike the GeForce GTX Titan X's 3,072 stream processors, the GeForce GTX 980 Ti only boasts 2,816 stream processors. They are distributed across 6 Graphics Processing Clusters (GPCs) and 22 Maxwell streaming multiprocessors. 22 SMM x 4 SMM x 32 ALU just give 2.816 GeForce GTX 980 Ti stream processors. Eight texture units are connected to each SMM, for a total of 176 texture units. The 16 raster operation pipelines provide a 64-bit interface, for a total of 384-bit interface with 96 ROPs.

The GM200 GPU of the GeForce GTX 980 Ti runs at a base frequency of 1,000 MHz, the minimum Boost bar is set to 1,075 MHz. Here we get an analogy with the GeForce GTX Titan X, which runs at the same clock speeds. The difference in performance between the two graphics cards may be due to the different number of stream processors, some differences in architecture, as well as a smaller memory configuration.

The GM200 GPU of the GeForce GTX 980 Ti provides the full feature set of the "Maxwell" architecture. So you get almost all the functional blocks present in the GeForce GTX Titan X. These include 3 MB of L2 cache, as opposed to 2 MB for the GeForce GTX 980 and GeForce GTX 970, where due to memory bandwidth limitations we get 1.792 kb. The cache bandwidth remains at 512 bytes per clock.

Specifications GeForce GTX 980 Ti

6 GB of GDDR5 memory is connected via a 384-bit interface. The memory operates at a clock frequency of 1.750 MHz. NVIDIA for some reason decided not to install 2000 MHz memory, which is already produced by SK Hynix and Samsung. NVIDIA also left High Bandwidth Memory for the next generation, which will be released under the code name "Pascal" next year. With a clock speed of 1.750 MHz and a 384-bit bus, the memory of the GeForce GTX 980 Ti operates at a bandwidth of 336.5 GB / s.

The maximum power consumption of the GeForce GTX 980 Ti NVIDIA indicates at 250 watts. Of course, the video card is compatible with SLI multi-GPU technology, which allows you to combine one, two and three video cards into one system.
