NVIDIA Quadro P4200 vs NVIDIA Quadro M620 vs NVIDIA Quadro P620

NVIDIA Quadro P4200

The Nvidia Quadro P4200 is a mobile high-end workstation graphics card for notebooks. It is based on the GP104 chip (like the consumer GeForce GTX 1070 or 1080 for laptops) and features 2304 shader cores. The clock rate is not disclosed but the theoretical SP performance is rated at 8.9 TFLOPs (for the fast Max-P version) and therefore faster than the old Quadro P5000 but below the Quadro P5200 (see table below). The P4200 is equipped with 8 GB GDDR5 which leads to 224 GB7s peak bandwidth due to the 256 Bit memory bus. There are two variants available, a Max-P performance version and a Max-Q version tuned for efficiency (with lower clock speeds).

The Quadro GPUs offer certified drivers, which are optimized for stability and performance in professional applications (CAD, DCC, medical, prospection, and visualizing applications). The performance in these areas is therefore much better compared to corresponding consumer GPUs.

Power Consumption

The power consumption of the Quadro P4200 is rated at 115 Watt TGP (max power consumption incl. memory) and therefore 15 Watt more than the Quadro P5000. The card is therefore best suited for large 17-inch 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.

NVIDIA Quadro P620

The Nvidia Quadro P620 is an entry-level mobile workstation graphics card for laptops. It uses a GP107 Pascal chip with a 128 Bit memory bus and therefore similar to the old Quadro P1000 with reduced clock speeds. Compared to consumer cards, there is no similar specified card currently and therefore the P620 slots in between the GeForce MX250 and GTX 1050. With a theoretical peak of 1.5 TFLOPS, the performance is clearly ahead of the old P600 with 1.2 TFLOPS.

The Quadro GPUs offer certified drivers, which are optimized for stability and performance in professional applications (CAD, DCC, medical, prospection, and visualizing applications). The performance in these areas is therefore much better compared to corresponding consumer GPUs.
