In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 4670 512MB are very slightly better than the AMD Radeon HD 6670 v2 MSI 2GB Edition.

The HD 6670 has a 50 MHz higher core clock speed than the HD 4670, but the HD 4670 has 8 more Texture Mapping Units than the HD 6670. As a result, the HD 4670 exhibits a 4.8 GTexel/s better Texture Fill Rate than the HD 6670. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 6670 has a 50 MHz higher core clock speed than the HD 4670 and the same number of Render Output Units. This results in the HD 6670 providing 0.4 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 6670 was released over a year more recently than the HD 4670, and so the HD 6670 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 4670.

The HD 6670 has 1536 MB more video memory than the HD 4670, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the HD 4670 has superior memory performance.

The HD 4670 has 4.3 GB/sec greater memory bandwidth than the HD 6670, which means that the memory performance of the HD 4670 is marginally better than the HD 6670.

The Radeon HD 6670 v2 MSI 2GB Edition has 480 Shader Processing Units and the Radeon HD 4670 512MB has 320. However, the actual shader performance of the HD 6670 is 192 and the actual shader performance of the HD 4670 is 168. The HD 6670 having 24 better shader performance is not particularly notable, as altogether the HD 4670 performs better when taking into account other relevant data.

The HD 6670 transistor size technology is 15 nm (nanometers) smaller than the HD 4670. This means that the HD 6670 is expected to run slightly cooler and achieve higher clock frequencies than the HD 4670. While they exhibit similar graphical performance, the HD 6670 should consume less power than the HD 4670.

The Radeon HD 6670 v2 MSI 2GB Edition requires 66 Watts to run and the Radeon HD 4670 512MB requires 59 Watts. We would recommend a PSU with at least 400 Watts for the HD 6670 and a PSU with at least 400 Watts for the HD 4670. The HD 6670 requires 7 Watts more than the HD 4670 to run. The difference is not significant enough for the HD 6670 to have a noticeably larger impact on your yearly electricity bills than the HD 4670.

GPU Mini Review

Mini ReviewOverview
Radeon HD 6670 v2 MSI 2GB Edition is a special edition of AMD's fast-middle-class Radeon HD 6670 v2, created by MSI.

Overclock: Central Unit
The Central Unit runs at the same speed.

Overclock: Memory Clock
The Operating Memory Clock runs at 667MHz and the Frame Buffer was raised to 2GB. This is a gimmick and in no way benefits the GPU.

Cooling Solution
The Cooling System remains the same.

Performance
Without Overclocking Out of The Box, Radeon HD 6670 v2 MSI 2GB Edition is as fast as the reference Radeon HD 6670 v2.
Overview
Radeon HD 4670 512MB is a Fast-Middle-Class Graphics Card based on the R700 Architecture.

Architecture
R700 was AMD's Second Unified Shader Architecture.

GPU
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.

Memory
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.

Features
DirectX 10.1 Support (10.0 Hardware Default) and support for Crossfire.



Power Consumption
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.

Performance
Gaming benchmarks put its performance somewhat below a GeForce GT 240.
