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	1.73	1.63
Recency	26 August 2013	12 December 2007
Maximum RAM amount	2 GB	512 MB
Chip lithography	28 nm	80 nm
Power consumption (TDP)	33 Watt	200 Watt

GT 740A has a 6.1% higher aggregate performance score, an age advantage of 5 years, a 300% higher maximum VRAM amount, a 185.7% more advanced lithography process, and 506.1% lower power consumption.

Given the minimal performance differences, no clear winner can be declared between GeForce GT 740A and Radeon HD 2900 PRO.

Be aware that GeForce GT 740A is a notebook card while Radeon HD 2900 PRO is a desktop one.
