Just a few days before the official launch of new Nvidia GM204 Maxwell based graphics cards, the Geforce GTX 980 and the Geforce GTX 970, we have full details regarding the GM204 GPU as well as more details regarding the Geforce GTX 980 graphics card which brings quite a few surprises considering it is based on a fully-enabled GM204 Maxwell GPU.


Thanks to Videocardz.com, which apparently managed to get a full press material for the Geforce GTX 980 launch, we now now that the Geforce GTX 980 will be based on a fully enabled GM204 Maxwell GPU.




Made on 28nm manufacturing process and packing 5.2 billion transistors on a 398 mm² die, the GM204 GPU is quite an interesting GPU as it features four Graphics Processing Clusters (GPCs), each with raster engine shared between four Streaming Multiprocessors Maxwell (SMMs) with 128 CUDA cores, which adds up to 2048 CUDA cores. It also has 2MB of L2 cache, which is four times the caceh on the GK104, 64 ROPs, which is twice more than on the GK104 and also comes with 128TMUs and a 256-bit wide memory interface.




The Geforce GTX 970 will be based on the same GM204 GPU but with 13 SMMs, which adds up to 1664 CUDA cores.

The reference Geforce GTX 980 will works at 1126MHz base GPU clock with 1216MHz GPU boost while 4GB of GDDR5 memory will be clocked 1750MHz (7.0GHz effective), which paired up with 256-bit memory interface adds up to 224GB/s of memory bandwidth. The TDP is set at 165W which shows the impressive power efficiency of the Maxwell GPU, something we already seen with the earlier launched GM107-based Geforce GTX 750 and GTX 750 Ti graphics cards.




The reference Geforce GTX 980 will also feature a total of five display outputs, including DVI-I, HDMI 2.0 and three DisplayPort 1.2 outputs.




Nvidia's new GM204 Maxwell GPU also brings a couple of new features including Dynamic Super Resolution, an upscaling technology that promises "4k Quality on a 1080p display", Third Generation Delta Color Compression, a technology that should help to increase memory efficiency, something that GTX 980 will certainly need due to its narrower 256-bit memory interface, as well as Multi-Pixel Programmable Sampling, a technology that improves sample randomization and reduce quantization artifacts.

In case you somehow managed to miss it, Nvidia plans to announced both the Geforce GTX 980 and the Geforce GTX 970 during its Game24 even scheduled for September 18th, 7:30PM PDT, which converts to early morning on September 19th for those in Europe. The rumored price is set at US $599 for the GTX 980 and US $399 for the Geforce GTX 970.
