In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 8870 (OEM) are significantly better than the Nvidia GeForce GTX 560 Club3D CoolStream Super OC 1GB Edition.

The HD 8870 has a 100 MHz higher core clock speed and 24 more Texture Mapping Units than the GTX 560. This results in the HD 8870 providing 29.6 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 8870 has a 100 MHz higher core clock speed than the GTX 560, but the GTX 560 has 8 more Render Output Units than the HD 8870. As a result, the GTX 560 exhibits a 4.8 GPixel/s better Pixel Fill Rate than the HD 8870. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 8870 was released over a year more recently than the GTX 560, and so the HD 8870 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 560.

The HD 8870 has 1024 MB more video memory than the GTX 560, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 8870 also has superior memory performance overall.

The HD 8870 has 22.3 GB/sec greater memory bandwidth than the GTX 560, which means that the memory performance of the HD 8870 is slightly better than the GTX 560.

The GeForce GTX 560 Club3D CoolStream Super OC 1GB Edition has 336 Shader Processing Units and the Radeon HD 8870 (OEM) has 1280. However, the actual shader performance of the GTX 560 is 605 and the actual shader performance of the HD 8870 is 1088. The HD 8870 having 483 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 8870 delivers a significantly smoother and more efficient experience when processing graphical data than the GTX 560.

The HD 8870 transistor size technology is 12 nm (nanometers) smaller than the GTX 560. This means that the HD 8870 is expected to run slightly cooler and achieve higher clock frequencies than the GTX 560.

The GeForce GTX 560 Club3D CoolStream Super OC 1GB Edition requires 176 Watts to run and the Radeon HD 8870 (OEM) requires 175 Watts. We would recommend a PSU with at least 450 Watts for the GTX 560 and a PSU with at least 500 Watts for the HD 8870. The GTX 560 requires 1 Watts more than the HD 8870 to run. The difference is not significant enough for the GTX 560 to have a noticeably larger impact on your yearly electricity bills than the HD 8870.

Benchmarks Indicate a 7% Performance Boost over the Reference GeForce GTX 560.
Radeon HD 8870 (OEM) is an OEM only, Performance Graphics Card based on the First Revision of the Graphics Core Next (GCN) Architecture.

The GCN Architecture succeeds the 40nm Terascale Architecture. In addition to being produced with a 28nm Technology, the GCN Architecture adds other Technologies that allow for energy efficiency. For example, ZeroCore Power, a long idle power saving technology, allows the Graphics Cards to shut down by itself when the Monitor is turned off.
GCN also adds Improved Anisotropic Filtering, DirectX 11 Tessellation and the Partially Resident Textures (PRT) Technology, which enables future games to utilize ultra-high resolution textures with the same performance as today's small and often repetitive textures.

It equips a GPU Codenamed Pitcairn XT which has 20 Compute Units activated and thus offers 1280 Shader Processing Units, 80 TMUs and 32 ROPs. The Central Unit is clocked at 1000MHz.

The GPU accesses a 2GB frame buffer of fast GDDR5, through a 256-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1200MHz.

Power Consumption
With a rated board TDP of 175W, it requires at least a 500W PSU with two available 6-pin connectors.

Radeon HD 8870 (OEM) is a Direct Rebrand of Radeon HD 7870 and performs exactly like it.

System Suggestions
Radeon HD 8870 (OEM) is best suited for resolutions up to and including 1920x1080. We recommend a Strong Processor (Intel Core i5 Quad Core/AMD FX Six Core) and 8GB of RAM for Optimal Performance.
