As we get closer to the launch of NVIDIA’s 900 series cards more and more information is leaking out. Courtesy of our friends over at VideoCardz we have the final specifications on the GeForce GTX 980 and quite a lot of information on the GM204 processor. Let’s dive in!
NVIDIA’s GM204 is the first GPU based on NVIDIA’s second generation Maxwell architecture. Many people expected a smaller fabrication process, but the GM204 is based on the 28 mm fabrication process. GM204 has four Graphics Processing Clusters (GPCs), each with four Streaming Multiprocessors “Maxwell” (SMM). There are four 64b memory controllers and the large L2 cache is accompanied by 64 ROPs. For those wondering the L2 cache is 2MB.
The 400 variant of the GPU that is going to be used in the GeForce GTX 980 has 16 SMMs. The big change here is that GM204 will have 64 Raster Operating units (ROPs), that’s more than Kepler GK110. The GM204 has the same number of Texture Mapping Units (TMUs), but since it has a higher clock the texture fillrate is actually higher. GM204 has 5.2 billion transistors and has a die size of 398 mm2.
NVIDIA is advertising some new technology with GM204, the first is Dynamic Super Resolution. This is new upscaling technology that is being called “4K quality on a 1080p display”. Next we have Third Generation Detal Color Compression. This is said to help with memory efficiency. Finally there is Multi-Pixel Programmable Sampling technology which improves sample randomization and reduces quantization artifacts.
NVIDIA GeForce GTX 980 Final Specifications
Below is a full list of the GeForce GTX 980’s specifications. The big thing to point out here is that the card will have 2048 CUDA cores, 128 TMUs and 64 ROPs. The card will come with 4 GB of GDDR5 memory across a 256-bit interface. The GTX 980 will have a base clock of 1126 MHz with a boost clock of 1216 MHz. All of this at a TDP of 165W. The card has HDMI 2.0 support.
