NVIDIA Quadro P620 vs NVIDIA Quadro P5000 vs NVIDIA Quadro P4200

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.

NVIDIA Quadro P5000

The Nvidia Quadro P5000 is a mobile high-end workstation graphics card for notebooks. Similar to the consumer GeForce GTX 1070 (Laptop), it is based on a slimmed-down GP104 chip with 2048 shaders. The graphics card is designed for the Kaby Lake generation and is the successor to the Quadro M5000M (Maxwell). However, the P5000 is equipped with 16 GB GDDR5 video memory (at a lower bandwidth), while GTX 1070 is limited to 8 GB. The clock rates range between 1164 MHz (base) to 1506 MHz (typical Boost) and up to 1657 MHz (max.). 

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.

Performance

The theoretical performance should be on par with the GTX 1070 (if the clocks did not take a massive hit), so the GPU should be significantly faster than the previous M5000M. Even the old M5500M could be beaten.

Power Consumption

The power consumption of the Quadro P5000 is similar to the old Quadro M5000M at 100 Watts TGP (max power consumption incl. memory) resp. 73.4 W TDP according to Nvidia. The card is therefore suited for large 17-inch notebooks.

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.
