AMD Radeon Pro Vega 20 vs NVIDIA Quadro P5000 Max-Q vs AMD Radeon Pro Vega 16

AMD Radeon Pro Vega 20

The AMD Radeon Pro Vega 20 is a dedicated graphics card for laptops. It was introduced as an option to the 2018 MacBook Pro. The graphics card offers 20 CUs (1,280 shaders) and 4 GB HBM2 memory. The performance should be on a level with the Radeon RX Vega M GL (also 1,280 shaders) and therefore between a Nvidia GeForce GTX 1050 and 1050 Ti.

NVIDIA Quadro P5000 Max-Q

The Nvidia Quadro P5000 Max-Q (official Nvidia Quadro P5000 with Max-Q Design) is a mobile high-end workstation graphics card for notebooks. It is the power efficient variant of the normal Quadro P5000 for laptops and offers slightly reduced clock speeds (1101 - 1366 MHz versus 1164 - 1506 MHz) and a greatly reduced power consumption (80 versus 100 Watt TGP). Similar to the consumer GeForce GTX 1070 Max-Q (Laptop), it is based on a slimmed-down GP104 chip with 2048 shaders. The graphics card is designed for the Kaby Lake generation. 

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 slightly below the normal Quadro P4000 due to the reduced clock speeds.

Power Consumption

With an TGP of 80 Watt, the P5000 Max-Q is only slightly higher rated (5 Watt) as the much slower Quadro P3000 (75 Watt) and therefore similar sized laptops can use the P5000 Max-Q. 

AMD Radeon Pro Vega 16

The AMD Radeon Pro Vega 16 is a dedicated graphics card for laptops. It was introduced as an option to the 2018 MacBook Pro. The graphics card offers 16 CUs (1024 shaders) and 4 GB HBM2 memory. The performance should be below the Radeon RX Vega M GL (1280 shaders) and therefore between a Nvidia GeForce GTX 1050 and 1050 Ti.
