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	9.82	17.57
Recency	6 May 2021	10 November 2021
Chip lithography	12 nm	8 nm
Power consumption (TDP)	30 Watt	60 Watt

T400 4 GB has 100% lower power consumption.

RTX A500, on the other hand, has a 78.9% higher aggregate performance score, an age advantage of 6 months, and a 50% more advanced lithography process.

The RTX A500 is our recommended choice as it beats the T400 4 GB in performance tests.
