AMD Radeon HD 6450: specs and benchmarks
AMD started Radeon HD 6450 sales 7 April 2011 at a recommended price of $55 . This is a TeraScale 2 architecture desktop card based on 40 nm manufacturing process and primarily aimed at office use. 1 GB of GDDR5 memory clocked at 800 GHz are supplied, and together with 64 Bit memory interface this creates a bandwidth of 25.6 GB/s.
Compatibility-wise, this is single-slot card attached via PCIe 2.0 x16 interface. Its manufacturer default version has a length of 168 mm. No additional power connector is required, and power consumption is at 30 Watt.
It provides poor gaming and benchmark performance at 0.51% of a leader's which is NVIDIA GeForce RTX 4090.

Synthetic benchmark performance of Radeon HD 6450. The combined score is measured on a 0-100 point scale.
Combined synthetic benchmark score
This is our combined benchmark performance score. We are regularly improving our combining algorithms, but if you find some perceived inconsistencies, feel free to speak up in comments section, we usually fix problems quickly.
This is probably the most ubiquitous benchmark, part of Passmark PerformanceTest suite. It gives the graphics card a thorough evaluation under various 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.
