HD 6450 is an entry-level Graphics Card based on the second revision of the Terascale Architecture.
The Second variant of the Terascale 2 Architecture is still manufactured with a 40nm technology and despite allowing more Stream Cores, their design remains more or less the same compared to the first variant.
It equips a GPU codenamed Caicos PRO which has 2 Compute Units activated and thus offers 160 Shader Processing Units, 8 TMUs and 4 ROPs. The Central Unit Operates at 625MHz.
The GPU accesses a 512MB frame buffer of fast GDDR5, through a 64-bit memory interface. The memory clock operates at 800MHz. The size of the frame buffer is adequate.
DirectX 11.0 Support (11.0 Hardware Default) and support for HD3D, Eyefinity, App Acceleration, PowerPlay and other technologies.
The Cooling Solution consists of a Single-Fan.
With a rated board TDP of 18W, it requires at least a 300W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.
Gaming benchmarks put its performance only slightly below of a GeForce GT 520.
We recommend a modest processor (Intel Celeron) and 4GB of RAM for a system with Radeon HD 6450.
