Radeon HD 4670 512MB Game Requirement Analysis
Radeon HD 4670 512MB is a Fast-Middle-Class Graphics Card based on the R700 Architecture.
R700 was AMD's Second Unified Shader Architecture.
It equips a GPU Codenamed RV730 XT which has 4 Compute Units activated and thus offers 320 Shader Processing Units, 32 TMUs and 8 ROPs. The Central Unit is clocked at 750MHz.
The GPU accesses a 512MB frame buffer of GDDR3, through a 128-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 800MHz.
DirectX 10.1 Support (10.0 Hardware Default) and support for Crossfire.
With a rated board TDP of 59W, it requires at least a 400W PSU and it relies entirely on the PCI slot for power meaning no extra connectors are required.
Gaming benchmarks put its performance somewhat below a GeForce GT 240.
