The Nvidia Quadro M4000M is a high-end, DirectX 12 (FL_12_1) and OpenGL 4.5 -compatible graphics card for mobile workstations. It is a Maxwell-based GPU built on the GM204 chip with all 1280 of the 1536 shader cores activated and is manufactured in 28 nm at TSMC. Therefore, the GPU is similar to the consumer Nvidia GeForce GTX 970M. The Quadro M4000M is built for the Intel Skylake generation and is a successor to the Quadro K4100M (Kepler-based). The M4000M usually comes with 4 GB GDDR5 VRAM clocked at 1250 MHz (5000 MHz effective, 160 GB/s Performance The clock speeds of the Quadro M4000M are very similar to the GTX 970M based on the same chip.

The base clock is slightly higher with 975 versus 924 MHz but the Boost speed is lower at 1013 versus 1038 MHz. Therefore, with good cooling the GTX 970M should be slightly faster. Compared to the Quadro line-up, it is the second fastest Quadro card in 2015 and therefore clearly faster than the old Quadro K4100M.
