Nvidia is rolling out updated versions of its mobile GPUs, if the latest rumors are to be believed.
WCCFTech reports that Nvidia will soon introduce the Geforce GTX 980MX and 970MX graphics cards, more powerful versions of the existing 980M and 970M, released in 2014, which currently dominate the mobile gaming market. If these reports are correct, the new chips should hit the market in the second quarter of this year.
On the surface, the GTX 980MX is something of a compromise between the existing GTX 980 desktop chips and the GTX 980M for laptops. The 980MX reportedly offers the same frame buffer, memory frequency, memory bandwidth, and TDP as the 980M, and has the same GM204 architecture at its core. But the 980MX offers 1664 CUDA cores to the 980M’s 1536 and 104 texture units to the 980M’s 96. The 980MX also offers a slightly higher clock speed of 1048 MHz to the 980M’s 1038 MHz.
| Model | GeForce GTX 980MX | GeForce GTX 980M | GeForce GTX 970MX | GeForce GTX 970M |
|---|---|---|---|---|
| Architecture | Maxwell | Maxwell | Maxwell | Maxwell |
| GPUs | GM204 | GM204 | GM204 | GM204 |
| CUDA cores | 1664 | 1536 | 1408 | 1280 |
| texture units | 104 | 96 | 88 | 80 |
| raster devices | 64 | 64 | 56 | 48 |
| clock speed | 1048MHz | 1038MHz | 941MHz | 924MHz |
| memory bus | 256 bit | 256 bit | 192 bit | 192 bit |
| frame buffer | 8/4GB GDDR5 | 8/4GB GDDR5 | 6/3GB GDDR5 | 6/3GB GDDR5 |
| memory frequency | 5000MHz | 5000MHz | 5000MHz | 5000MHz |
| memory bandwidth | 160GB/s | 160GB/s | 120GB/s | 120GB/s |
| TDP | 125W | 125W | 100W | 100W |
The less powerful GTX 970MX reportedly has a similar ratio to the existing 970M, with a slightly higher number of CUDA cores and more texture units, but otherwise similar specs. The chart above shows the differences.
Everything is hypothetical at this point. Nothing has been officially announced and it is unclear who WCCTech’s sources are.
Having said that, it’s likely that Nvidia will announce something soon, if not this then something else. The leak comes after rival GPU maker AMD revealed its upcoming Polaris lineup at CES 2016, which includes some pretty big news in terms of power efficiency.
Nvidia’s current mobile GPUs have dominated the gaming laptop market for some time now, but that could easily change if AMD’s numbers prove correct. It will be interesting to see what Nvidia finally announces.
