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	8.24	9.41
Recency	25 July 2011	6 May 2021
Maximum RAM amount	3 GB	2 GB
Chip lithography	40 nm	12 nm
Power consumption (TDP)	238 Watt	30 Watt

Tesla C2050 has a 50% higher maximum VRAM amount.

T400, on the other hand, has a 14.2% higher aggregate performance score, an age advantage of 9 years, a 233.3% more advanced lithography process, and 693.3% lower power consumption.

The T400 is our recommended choice as it beats the Tesla C2050 in performance tests.
