NVIDIA Quadro M600M vs NVIDIA Quadro M620 vs NVIDIA Quadro 4000M

NVIDIA Quadro M600M

The 28nm NVIDIA Quadro M600M is an entry-level DirectX 12 (FL 11_0) and OpenGL 4.5-compatible graphics card for mobile workstations. It is a 1st generation Maxwell GPU that is most likely built on the GM107 architecture with 384 of the 640 shader cores activated. Compared to the older Quadro K620M and consumer GeForce 940M, the GPU offers a 128-Bit memory bus that separates it from the GM108-based K620M. The M600M typically comes with 2 GB GDDR5 VRAM clocked at 1250 MHz (5000 MHz effective at 80 GB/s instead of 16 GB/s on the K620M). 

In the Lenovo Thinkpad P70 the M600M is clocked at 837 - 876 MHz (Boost) for the shaders, and 1253 MHz (5012 MHz effektive) for the 2 GB GDDR5 from Samsung (thanks to our reader John for the GPU-Z screenshot).

The Quadro series offers certified drivers that are optimized for stability and performance in professional applications like CAD or DCC. OpenGL performance, for example, should be significantly better compared to GeForce graphics cards of similar specifications.

Performance

The Quadro M600M is about 20% faster than the previous Quadro K620M thanks to the wider 128-bit memory interface and pretty much right between the siblings Quadro M500M & Quadro M1000M. The consumer GPU GeForce 940MX is beaten by ~10-15%, while the GeForce GTX 950M is another 20% faster.

Using CUDA (Compute Capability 5.0) or OpenCL 1.2, the cores of the Quadro M600M can be used for general calculations.

Power Consumption

The power consumption of the Quadro M600M is rated at the same 30 Watt TGP as the K620M including the board and memory components. Therefore, the card is also suited for thin and light notebooks.

NVIDIA Quadro M620

The 28nm NVIDIA Quadro M620 is a mid-range DirectX 12 (FL 11_0) and OpenGL 4.5-compatible graphics card for mobile workstations. It is a 1st generation Maxwell-based GPU built on the GM107 architecture with 512 of the 640 shader cores activated. Therefore, the GPU is not similar to any current consumer card. The Geforce GTX 950M, for example, uses the full 640 shader cores. The older Quadro M1000M offers very similar specs (same amount of shader cores and also based on the same chip but more graphics memory), but was intended for the Skylake generation. The M620 is intended for the Kaby Lake generation.

The Quadro series offers certified drivers that are optimized for stability and performance in professional applications like CAD or DCC. OpenGL performance, for example, should be significantly better compared to GeForce graphics cards of similar specifications.

Performance

Due to the smaller amount of memory, the Quadro M620 should be slightly slower than the older Quadro M1000M. However, the exact clock speeds are not known up to now. In early benchmarks we have, the M1000M is about 9 % faster than the M620 in SPECviewperf 12.

Using CUDA (Compute Capability 5.0) or OpenCL 1.2, the cores of the Quadro M620 can be used for general calculations.

Power Consumption

The power consumption of the Quadro M620 is rated for a 30 Watt TGP including the board and memory components (21.2 Watt TDP), which is 10 Watt lower than the M1000M (which offers more memory). Therefore, the card is suited for 15-inch notebooks and greater.
