In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7850 XFX Core Edition are massively better than the AMD Radeon HD 4670 AGP.

The HD 7850 has a 110 MHz higher core clock speed and 32 more Texture Mapping Units than the HD 4670. This results in the HD 7850 providing 31 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 HD 7850 has a 110 MHz higher core clock speed and 24 more Render Output Units than the HD 4670. This results in the HD 7850 providing 21.5 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 7850 was released over three years more recently than the HD 4670, and so the HD 7850 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 4670 when running the latest games.

The Radeon HD 7850 XFX Core Edition and the Radeon HD 4670 AGP have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The HD 7850 has 134.4 GB/sec greater memory bandwidth than the HD 4670, which means that the memory performance of the HD 7850 is massively better than the HD 4670.

The Radeon HD 7850 XFX Core Edition has 1024 Shader Processing Units and the Radeon HD 4670 AGP has 320. However, the actual shader performance of the HD 7850 is 749 and the actual shader performance of the HD 4670 is 168. The HD 7850 having 581 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7850 delivers a massively smoother and more efficient experience when processing graphical data than the HD 4670.

The HD 7850 transistor size technology is 27 nm (nanometers) smaller than the HD 4670. This means that the HD 7850 is expected to run slightly cooler and achieve higher clock frequencies than the HD 4670.

The Radeon HD 4670 AGP requires 59 Watts to run but there is no entry for the HD 7850. We would recommend a PSU with at least 500 Watts for the HD 7850 and a PSU with at least 400 Watts for the HD 4670. The HD 7850 has been recommended a PSU with 100 Watts more than the HD 4670. The difference is significant enough that the HD 7850 may have an adverse affect on your yearly electricity bills in comparison to the HD 4670.

GPU Mini Review

Mini ReviewRadeon HD 7850 XFX Core Edition is a special edition of the powerful Radeon HD 7850. See the standard version for more information about it.
This edition features a special cooling system that allows twice as much heat dissipation when compared to the reference AMD cooling system but its performance is still the same, as there's no over-clocking out of the box.
Overview
Radeon HD 4670 AGP 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 1GB 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.
