For the first time in many years NVIDIA is launching a new GPU at the famed Computex show in Taipei Taiwan. The new GPU, the GTX 980 Ti will become the new retail flagship for NVIDIA replacing the current GTX 980 and brings with it a focus on 4K gaming performance, DX 12 performance and feature support and Gameworks VR.
The GeForce GTX 980 Ti is based on the GM200 GPU. Comprised of 8 billion transistors, GM200 is the most powerful GPU nvidia has ever built and the heart of the TitanX.
The GM200 GPU used in the GeForce GTX 980 Ti ships with 22 SM units and is composed of 2816 CUDA Cores, while 176 texture units are available for texture processing. Compared to the GeForce GTX 980, this is 38% more CUDA Cores and texture units. The GeForce GTX 980 Ti runs at a base clock frequency of 1000MHz, while the boost clock speed is 1075MHz. The integrated boost clock scales based on a power target and GPU temperature so actual GPU scaling can vary depending on your environmental conditions.
The GeForce GTX 980 Ti ships with a 384-bit memory interface running at 7GHz effective memory clock. Peak memory bandwidth is 50% higher than GTX 980 at 336.5GB/sec and nvidia has equipped the GeForce GTX 980 Ti with 6GB of GDDR5 memory. GM200 also ships with 3MB of L2 cache and 96 ROPs.
While all of those numbers are impressive NVIDIA claims that the new GeForce GTX 980 Ti is 3X faster than the GeForce GTX 680, and up to 65% faster than the GeForce GTX 780 Ti. Also given the 6GB memory frame buffer the GPU can scale faster as screen resolution increases making it a perfect match for 4K gaming with details set to maximum.
Like most high-end GPUs the GeForce GTX 980 Ti also supports SLI for even greater performance and unlike for mentioned high-end cards like the GTX 780 Ti and GTX 680 the 980 Ti scales better with an average boost of 80% in most DX11 games. Normally this kind of scaling is reserved for mid-range cards with lower performance ceilings.
