In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 8670M are very slightly better than the AMD Radeon HD 7670M.

The Radeon HD 8670M has a 175 MHz higher core clock speed and the same number of Texture Mapping Units as the Radeon HD 7670M. This results in the Radeon HD 8670M providing 4.2 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The Radeon HD 8670M has a 175 MHz higher core clock speed than the Radeon HD 7670M, but the Radeon HD 7670M has 8 more Render Output Units than the Radeon HD 8670M. As a result, the Radeon HD 7670M exhibits a 3.4 GPixel/s better Pixel Fill Rate than the Radeon HD 8670M. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Radeon HD 8670M was released over a year more recently than the Radeon HD 7670M, and so the Radeon HD 8670M is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Radeon HD 7670M.

The Radeon HD 8670M and the Radeon HD 7670M have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The Radeon HD 7670M has 14.4 GB/sec greater memory bandwidth than the Radeon HD 8670M, which means that the memory performance of the Radeon HD 7670M is slightly better than the Radeon HD 8670M.

The Radeon HD 8670M has 384 Shader Processing Units and the Radeon HD 7670M has 480. However, the actual shader performance of the Radeon HD 8670M is 269 and the actual shader performance of the Radeon HD 7670M is 144. The Radeon HD 8670M having 125 better shader performance is not particularly notable, as altogether the Radeon HD 7670M performs better when taking into account other relevant data.

The Radeon HD 8670M transistor size technology is 12 nm (nanometers) smaller than the Radeon HD 7670M. This means that the Radeon HD 8670M is expected to run slightly cooler and achieve higher clock frequencies than the Radeon HD 7670M. While they exhibit similar graphical performance, the Radeon HD 8670M should consume less power than the Radeon HD 7670M.

The Radeon HD 7670M requires 20 Watts to run but there is no entry for the Radeon HD 8670M.

GPU Mini Review

Mini ReviewRadeon HD 8670M is a middle-class Graphics Card based on the GCN architecture.
It features the Mars XT GPU and thus offers 384 Shader Processing Units, 24 TMUs and 8 ROPs. The central unit can be initially clocked at up to 775MHz reach up to 825MHz in Turbo Mode while the memory interface is of 64-bit of standard DDR3.
It can be addressed as a fast Radeon HD 8550M due to its considerably higher core-clock speed.
Benchmarks indicate its performance is somewhat above NVIDIA's GeForce GT 630M and thus the card can run most modern games at medium games.
Overview
Radeon HD 7670M is a Middle-Class Mobile 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 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.

Memory
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.

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

Power Consumption
With a rated board TDP of 20W, it is suited for average sized laptops.

Performance
Gaming benchmarks put its performance somewhere between GeForce GT 540M and GeForce GT 550M.

System Suggestions
We recommend a modest processor (Intel Core i3 Mobile and 4GB of RAM for a system with Radeon HD 7670M.
