In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 6800 Ultra are very slightly better than the AMD Radeon HD 6450 v3 Sapphire 1GB Edition.

The HD 6450 was released over three years more recently than the GeForce 6800 Ultra, and so the HD 6450 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce 6800 Ultra when running the latest games.

The HD 6450 has 768 MB more video memory than the GeForce 6800 Ultra, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The GeForce 6800 Ultra has 24.5 GB/sec greater memory bandwidth than the HD 6450, which means that the memory performance of the GeForce 6800 Ultra is slightly better than the HD 6450.

The Radeon HD 6450 v3 Sapphire 1GB Edition has 160 Shader Processing Units and the GeForce 6800 Ultra has 22. However, the actual shader performance of the HD 6450 is 50 and the actual shader performance of the GeForce 6800 Ultra is 9. The HD 6450 having 41 better shader performance is not particularly notable, as altogether the GeForce 6800 Ultra performs better when taking into account other relevant data.

The Radeon HD 6450 v3 Sapphire 1GB Edition requires 18 Watts to run and the GeForce 6800 Ultra requires 124 Watts. We would recommend a PSU with at least 400 Watts for the HD 6450. The GeForce 6800 Ultra requires 106 Watts more than the HD 6450 to run. The difference is significant enough that the GeForce 6800 Ultra may have an adverse affect on your yearly electricity bills in comparison to the HD 6450.

Mini ReviewOverview
Radeon HD 6450 v3 Sapphire 1GB Edition is a special edition of AMD's Entry-Level Radeon HD 6450 v3, created by Sapphire.

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 Doubled to 1GB. This is a gimmick and in no way benefits the GPU.

Cooling Solution
The Cooling System remains the same.

Without Overclocking Out of The Box, Radeon HD 6450 v3 Sapphire 1GB Edition is as fast as the reference Radeon HD 6450 v3.
