In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 4870 Sapphire Vapor-X 1GB Edition are marginally better than the Nvidia GeForce GTX 650 Gigabyte OC 1GB Edition.

The GTX 650 has a 360 MHz higher core clock speed but 8 fewer Texture Mapping Units than the HD 4870. The lower TMU count doesn't matter, though, as altogether the GTX 650 manages to provide 5.5 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 650 has a 360 MHz higher core clock speed than the HD 4870 and the same number of Render Output Units. This results in the GTX 650 providing 5.8 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 650 was released over three years more recently than the HD 4870, and so the GTX 650 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 4870 when running the latest games.

The Radeon HD 4870 Sapphire Vapor-X 1GB Edition and the GeForce GTX 650 Gigabyte OC 1GB Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The HD 4870 has 35.2 GB/sec greater memory bandwidth than the GTX 650, which means that the memory performance of the HD 4870 is noticeably better than the GTX 650.

The Radeon HD 4870 Sapphire Vapor-X 1GB Edition has 800 Shader Processing Units and the GeForce GTX 650 Gigabyte OC 1GB Edition has 384. However, the actual shader performance of the HD 4870 is 420 and the actual shader performance of the GTX 650 is 426. The GTX 650 having 6 better shader performance is not particularly notable, as altogether the HD 4870 performs better when taking into account other relevant data.

The GTX 650 transistor size technology is 27 nm (nanometers) smaller than the HD 4870. This means that the GTX 650 is expected to run slightly cooler and achieve higher clock frequencies than the HD 4870. While they exhibit similar graphical performance, the GTX 650 should consume less power than the HD 4870.

The Radeon HD 4870 Sapphire Vapor-X 1GB Edition requires 150 Watts to run but there is no entry for the GeForce GTX 650 Gigabyte OC 1GB Edition. We would recommend a PSU with at least 500 Watts for the HD 4870 and a PSU with at least 400 Watts for the GTX 650. The HD 4870 has been recommended a PSU with 100 Watts more than the GTX 650. The difference is significant enough that the HD 4870 may have an adverse affect on your yearly electricity bills in comparison to the GTX 650.

GPU Mini Review

Mini ReviewOverview
Radeon HD 4870 Sapphire Vapor-X 1GB Edition is a special edition of AMD's High-End Radeon HD 4890, created by Sapphire.

Overclock: Central Unit
The Central Unit remains the same.

Overclock: Memory Clock
The Operating Memory Clock remains the same while the Frame Buffer was doubled to 1GB: useful at higher resolutions.

Cooling Solution
The Cooling System has been replaced by Sapphire's Vapor-X Cooling Solution, which has cooling module on the GPU together with a heatsink and profiled fan venting heat out of the case.

Performance
Benchmarks indicate a 3% performance over the reference Radeon HD 4870.
GeForce GTX 650 Gigabyte OC 1GB Edition is a special edition of the fast-middle-class GeForce GTX 650 1GB.
This special edition comes overclocked out of the box to 1110MHz and features a custom-designed 10 cm cooler.
Benchmarks indicate a 4% performance boost when compared to the reference card and so this GPU is suitable for medium to high settings on most demanding games but not with extreme resolutions.
