The guys from Videocardz bring us the exclusive final specification of the GeForce GTX 980 from Nvidia. It’s based on 2nd generation architecture from Maxwell with a GMU204 GPU. Actually, the GM204-400 GPU comprised with 16 Streaming Multiprocessors Maxwell (SMM), 128 Texture Mapping Units (TMUs) and 64 Raster Operating Units (ROPs). Yes, more than are offered on the high-quality GPU (GK 110).
Yes it counts on less TMUs, so it is expected that higher frequencies will help to achieve an increase in the fill of the textures (Texture Fill rate). The rest of the features that concern the silicon are complete with 5,200 million transistors, 2 MB of L2 cache and the die size of 398 mm2.
One of the interesting technologies to be implemented with the Nvidia GPU Maxwell GM204 is called Dynamic Super Resolution, which is basically resizing a low quality 4K image under a Full HD (1080p) screen. The addition of the 3rd Generation of color compression Delta (Third Generation Delta Color compression) technology that helps increase memory efficiency, something more than necessary to use a 256-bit interface.
Lastly, Multi-Pixel Programmable Sampling technology which improves the randomness of sampling and reduces the number of devices
Continuing, we find the diagram of the GPU and can see the die of the GM204 has been divided into four Graphics Processing Clusters (GPCs). Each GPC has 4 SMM’s that lead to a 64 bit memory controller. The L2 cache is accompanied by 64 ROPs.
Ultimately, the Nvidia GeForce GTX 980 will come with a total of 2048 CUDA Cores, 128 TMUs and 64 ROPs a base frequency of 1126 MHz (1216 MHz Boost) attached to 4 GB of GDDR5 memory @ 7.0 GHz with a memory interface 256 bits and with the same bandwidth as the GeForce GTX 770, 224 GB/s, the difference resulting in a higher overall performance thanks to the new architecture and more CUDA cores and more frequencies but with a use of 165W before 250W from its predecessor based on the GK110 GPU.
The GeForce GTX 980 is powered by two PCI-Express 6-pin connectors and offers five display outputs as a DVI-I, the awaited HDMI 2.0, three DisplayPort’s 1.2 and is expected to reach a price of 590 dollars. The official announcement is on September 19th.
