Passmark

This is the most ubiquitous GPU benchmark. It gives the graphics card a thorough evaluation under various types of load, providing four separate benchmarks for Direct3D versions 9, 10, 11 and 12 (the last being done in 4K resolution if possible), and few more tests engaging DirectCompute capabilities.

Pros & cons summary

Performance score	31.77	43.32
Recency	1 December 2020	13 October 2022
Maximum RAM amount	8 GB	48 GB
Chip lithography	7 nm	5 nm
Power consumption (TDP)	225 Watt	300 Watt

Pro V520 has 33.3% lower power consumption.

L40S, on the other hand, has a 36.4% higher aggregate performance score, an age advantage of 1 year, a 500% higher maximum VRAM amount, and a 40% more advanced lithography process.

The L40S is our recommended choice as it beats the Radeon Pro V520 in performance tests.
