Summary
AMD started Radeon HD 6450A sales 7 April 2011. This is a TeraScale 2 architecture desktop card based on 40 nm manufacturing process and primarily aimed at office use. 512 MB of DDR3 memory clocked at 1.07 GHz are supplied, and together with 64 Bit memory interface this creates a bandwidth of 8.528 GB/s.
Compatibility-wise, this is card attached via MXM-A (3.0) interface. No additional power connector is required, and power consumption is at 25 Watt.
It provides poor gaming and benchmark performance at
0.66%
of a leader's which is NVIDIA GeForce RTX 4090.
