In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 MSI Hawk 2GB Edition are massively better than the AMD Radeon HD 5670 Gigabyte 1GB OC Edition.

The GTX 660 has a 135 MHz higher core clock speed and 60 more Texture Mapping Units than the HD 5670. This results in the GTX 660 providing 67.8 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 GTX 660 has a 135 MHz higher core clock speed and 16 more Render Output Units than the HD 5670. This results in the GTX 660 providing 18.4 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 GTX 660 was released over a year more recently than the HD 5670, and so the GTX 660 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 5670.

The GTX 660 has 1024 MB more video memory than the HD 5670, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 660 also has superior memory performance overall.

The GTX 660 has 80.2 GB/sec greater memory bandwidth than the HD 5670, which means that the memory performance of the GTX 660 is much better than the HD 5670.

The Radeon HD 5670 Gigabyte 1GB OC Edition has 400 Shader Processing Units and the GeForce GTX 660 MSI Hawk 2GB Edition has 960. However, the actual shader performance of the HD 5670 is 190 and the actual shader performance of the GTX 660 is 1104. The GTX 660 having 914 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 660 delivers a massively smoother and more efficient experience when processing graphical data than the HD 5670.

The GTX 660 transistor size technology is 12 nm (nanometers) smaller than the HD 5670. This means that the GTX 660 is expected to run slightly cooler and achieve higher clock frequencies than the HD 5670.

GPU Mini Review

Mini ReviewRadeon HD 5670 Gigabyte 1GB OC Edition is a special edition of the middle-class Radeon HD 5670.
This edition features a new cooling system and overclocking out of the box in the core-clock from 775MHz to 950MHz.
There are no benchmarks available and so this GPU's rank is predicted.
GeForce GTX 660 MSI Hawk 2GB Edition a special edition of GeForce GTX 660.
The new features include the Twin Frozr III Thermal Design cooling solution which, according to MSI, generates 20% more airflow than traditional fan design.
In terms of overclocking, the base-clock was increased from 980MHz to 1085MHz and the boost clock can now reach 1150MHz, instead of 1033MHz. The memory clock was left untouched.
The overclocking is therefore extreme and the performance boost is around 8% when compared to the standard GeForce GTX 660.
