In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7670 v2 are noticeably better than the AMD Radeon HD 3800 series.

The HD 3800 has no core clock speed set, so any comparison between Texture and Pixel Fill Rates is not currently possible.

The HD 7670 was released over three years more recently than the HD 3800, and so the HD 7670 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 3800 when running the latest games.

The HD 7670 has 1536 MB more video memory than the HD 3800, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7670 also has superior memory performance overall.

The HD 7670 has 25.6 GB/sec greater memory bandwidth than the HD 3800, which means that the memory performance of the HD 7670 is slightly better than the HD 3800.

The Radeon HD 7670 v2 has 480 Shader Processing Units and the Radeon HD 3800 series has 320. However, the actual shader performance of the HD 7670 is 192 and the actual shader performance of the HD 3800 is 0. The HD 7670 having 192 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7670 delivers a noticeably smoother and more efficient experience when processing graphical data than the HD 3800.

The HD 7670 transistor size technology is 15 nm (nanometers) smaller than the HD 3800. This means that the HD 7670 is expected to run slightly cooler and achieve higher clock frequencies than the HD 3800.

The Radeon HD 7670 v2 requires 66 Watts to run but there is no entry for the Radeon HD 3800 series. We would recommend a PSU with at least 400 Watts for the HD 7670.

GPU Mini Review

Mini ReviewOverview
Radeon HD 7670 v2 is a fast-middle-class 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 Turks XT which has 8 Compute Units activated and thus offers 480 Shader Processing Units, 24 TMUs and 8 ROPs.

Memory
The GPU accesses a 1GB frame buffer of DDR3, through a 128-bit memory interface. The memory clock operates at 800MHz. 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 Crossfire, 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 66W, it requires at least a 400W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.

Performance
Radeon HD 7670 v2 is a direct re-brand of Radeon HD 6670 v2.
Gaming benchmarks put its performance somewhat above GeForce GT 440, meaning GeForce GTS 450 is still much faster.

System Suggestions
We recommend a modest processor (Intel Core i3/AMD Phenom) and 4GB of RAM for a system with Radeon HD 7670 v2.
Radeon HD 3800 Series is not a GPU but instead a combination between Radeon HD 3830, Radeon HD 3850 and Radeon HD 3870 whose rank is a balance between the three and that exists for System Requirements purposes only.
