Radeon HD 7670M Review
Radeon HD 7670M is a Middle-Class Mobile 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 Thames XT which has 6 Compute Units activated and thus offers 480 Shader Processing Units, 24 TMUs and 8 ROPs. The Central Unit runs at 600MHz.
The GPU accesses a 1GB frame buffer of DDR3, through a 128-bit memory interface. The memory clock operates at 900MHz. The size of the frame buffer is adequate.
DirectX 11.0 Support (11.0 Hardware Default) and support for Crossfire, HD3D, Eyefinity, App Acceleration, PowerPlay and other technologies.
With a rated board TDP of 20W, it is suited for average sized laptops.
Gaming benchmarks put its performance somewhere between GeForce GT 540M and GeForce GT 550M.
We recommend a modest processor (Intel Core i3 Mobile and 4GB of RAM for a system with Radeon HD 7670M.
