A new report published by HWbattle claims NVIDIA is going to release successors to the GTX 980M and GTX 970M mobile GPUs later this year.
According to the report, the GTX 980MX will replace the GTX 980M while the GTX970MX will replace the GTX 970M GPU. Apparently, the GTX 980MX will be based on the NVIDIA Maxwell architecture with 1664 CUDA cores, 104 TMUs, and 64 ROPs. It could ship with a core clock of 1048MHz and a memory clock of 5.00GHz. Two different variations might be offered – one with 4GB GDDR5 memory and another with 8GB of GDDR5 memory, both on a 256-bit bus interface. As far as TDP goes, the GTX 980MX is likely to retain the same 125W rating as the current GTX 980M.
The GTX 970MX on the other hand will be based on a stripped down GM204 core with 1408 CUDA cores, 88 TMUs, and 56 ROPs. It will ship with a lower 941MHz core clock and a 5.00GHz memory clock. The GPU is likely to arrive in two versions – one with 3GB of GDDR5 memory and the other with 6GB of GDDR5 memory, on a 192-bit memory interface. It is said to have a TDP of around 100W, similar to its predecessor.
Both GPUs should show up in high-end gaming notebooks sometime in Q2 this year.
