The NVIDIA GeForce 940MX is a refreshed version of the older 940M mobile chip but paired with a faster GDDR5 memory (in some cases) and slightly higher clock speeds, which result in noticeably better performance compared to the standard 940M. However, some OEMs will still choose to use the cheaper DDR3 version of the GPU.
Announced back in the first quarter of 2016, the chip is almost identical to the standard 940M (Maxwell) but with clock speeds increased up to 1242 MHz and base 1122 MHz. Again, the memory uses a 64-bit bus and has 4GB of DDR3 VRAM. It still supports the DirectX 12 API and Shader 5.0 feature along with the usual NVIDIA technologies – CUDA, GPU Boost 2.0, Optimus, GeForce Experience, PhysX. The whole graphics card is rated at around 15 to 30 Watts depending on the clock speeds and memory used in the specific notebook.
