In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 480 3-way SLI are significantly better than the AMD Radeon HD 7870 PCS+ Vortex II Edition.

The HD 7870 has a 449 MHz higher core clock speed than the GTX 480, but the GTX 480 has 100 more Texture Mapping Units than the HD 7870. As a result, the GTX 480 exhibits a 34.2 GTexel/s better Texture Fill Rate than the HD 7870. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 7870 has a 449 MHz higher core clock speed than the GTX 480, but the GTX 480 has 112 more Render Output Units than the HD 7870. As a result, the GTX 480 exhibits a 64.1 GPixel/s better Pixel Fill Rate than the HD 7870. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 7870 was released over a year more recently than the GTX 480, and so the HD 7870 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 480.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The GTX 480 has 1024 MB more video memory than the HD 7870, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 480 also has superior memory performance overall.

The GTX 480 has 194.8 GB/sec greater memory bandwidth than the HD 7870, which means that the memory performance of the GTX 480 is massively better than the HD 7870.

The GeForce GTX 480 3-way SLI has 1440 Shader Processing Units and the Radeon HD 7870 PCS+ Vortex II Edition has 1280. However, the actual shader performance of the GTX 480 is 2019 and the actual shader performance of the HD 7870 is 1251. The GTX 480 having 768 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 480 delivers a massively smoother and more efficient experience when processing graphical data than the HD 7870.

The HD 7870 transistor size technology is 12 nm (nanometers) smaller than the GTX 480. This means that the HD 7870 is expected to run slightly cooler and achieve higher clock frequencies than the GTX 480.

The GeForce GTX 480 3-way SLI requires 750 Watts to run but there is no entry for the Radeon HD 7870 PCS+ Vortex II Edition. We would recommend a PSU with at least 1000 Watts for the GTX 480 and a PSU with at least 500 Watts for the HD 7870. The GTX 480 has been recommended a PSU with 500 Watts more than the HD 7870. The difference is significant enough that the GTX 480 may have an adverse affect on your yearly electricity bills in comparison to the HD 7870.
