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.

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	1.49	0.75
Recency	1 July 2014	5 January 2012
Maximum RAM amount	1 GB	512 MB
Chip lithography	28 nm	40 nm
Power consumption (TDP)	33 Watt	25 Watt

GT 720A has a 98.7% higher aggregate performance score, an age advantage of 2 years, a 100% higher maximum VRAM amount, and a 42.9% more advanced lithography process.

HD 7450A, on the other hand, has 32% lower power consumption.

The GeForce GT 720A is our recommended choice as it beats the Radeon HD 7450A in performance tests.
