NVIDIA is reportedly preparing faster mobile GPUs based on Maxwell, with a GTX 980MX and 970MX on the way.
The new GTX 980MX would sit between the GTX 980M and the laptop version of the full GTX 980, with 1664 CUDA cores (compared to 1536 with the 980M), 104 Texture Units (up from the 980M's 96), a 1048 MHz core clock, and up to 8 GB of GDDR5. Memory speed and bandwidth will reportedly be identical to the GTX 980M at 5000 MHz and 160 GB/s respectively, with both GPUs using a 256-bit memory bus.
The GTX 970MX represents a similar upgrade over the existing GTX 970M, with CUDA Core count increased from 1280 to 1408, Texture Units up from 80 to 88, and 8 additional raster devices available (56 vs. 48). Both the 970M and 970MX use 192-bit GDDR5 clocked at 5000 MHz, and available with the same 3 GB or 6 GB of frame buffer.
WCCFtech prepared a chart to demonstrate the differences between NVIDIA's mobile offerings:
|Model||GeForce GTX 980 Laptop Version||GeForce GTX 980MX||
GeForce GTX 980M
|GeForce GTX 970MX||GeForce GTX 970M||GeForce GTX 965M||
GeForce GTX 960M
|Clock Speed||1218 MHz||1048 MHz||1038 MHz||941 MHz||924 MHz||950 MHz||1097 MHz|
|Frame Buffer||8 GB GDDR5||8/4 GB GDDR5||8/4 GB GDDR5||6/3 GB GDDR5||6/3 GB GDDR5||4 GB GDDR5||4 GB GDDR5|
|Memory Frequency||7008 MHz||5000 MHz||5000 MHz||5000 MHz||5000 MHz||5000 MHz||5000 MHz|
|Memory Bandwidth||224 GB/s||160 GB/s||160 GB/s||120 GB/s||120 GB/s||80 GB/s||80 GB/s|
These new GPUs will reportedly be based on the same Maxwell GM204 core, and TDPs are apparently unchanged at 125W for the GTX 980MX, and 100W for the 970MX.
We will await any official announcement.
