Overview
Radeon HD 6450 v4 is an entry-level Graphics Card based on the second revision of the Terascale Architecture.

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.

GPU
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 650MHz.

Memory
The GPU accesses a 2GB frame buffer of GDDR3, through a 64-bit memory interface. The memory clock operates at 580MHz. The size of the frame buffer is exaggerated and in no way benefits the GPU.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for HD3D, Eyefinity, App Acceleration, PowerPlay and other technologies.

Cooling Solution
The Cooling Solution consists of a Single-Fan.

Power Consumption
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.

Performance
Gaming benchmarks put its performance around of a GeForce GT 420.

System Suggestions
We recommend a modest processor (Intel Celeron) and 2GB of RAM for a system with Radeon HD 6450 v4.
