Let's see how good the compared graphics cards are for gaming. Particular gaming benchmark results are measured in FPS.

Pros & cons summary

Performance score	3.55	3.48
Recency	29 May 2013	13 November 2008
Maximum RAM amount	1 GB	2 GB
Chip lithography	28 nm	55 nm
Power consumption (TDP)	49 Watt	160 Watt

GT 640 Rev. 2 has a 2% higher aggregate performance score, an age advantage of 4 years, a 96.4% more advanced lithography process, and 226.5% lower power consumption.

FireStream 9270, on the other hand, has a 100% higher maximum VRAM amount.

Given the minimal performance differences, no clear winner can be declared between GeForce GT 640 Rev. 2 and FireStream 9270.

Be aware that GeForce GT 640 Rev. 2 is a desktop card while FireStream 9270 is a workstation one.
