In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 280X Crossfire are significantly better than the AMD Radeon HD 8970 (OEM).

The HD 8970 has a 75 MHz higher core clock speed than the R9 280X, but the R9 280X has 128 more Texture Mapping Units than the HD 8970. As a result, the R9 280X exhibits a 99.2 GTexel/s better Texture Fill Rate than the HD 8970. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 8970 has a 75 MHz higher core clock speed than the R9 280X, but the R9 280X has 32 more Render Output Units than the HD 8970. As a result, the R9 280X exhibits a 24.8 GPixel/s better Pixel Fill Rate than the HD 8970. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The R9 280X was released less than a year after the HD 8970, and so they are likely to have similar driver support for optimizing performance when running the latest games.

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 R9 280X has 3072 MB more video memory than the HD 8970, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the R9 280X also has superior memory performance overall.

The R9 280X has 312 GB/sec greater memory bandwidth than the HD 8970, which means that the memory performance of the R9 280X is massively better than the HD 8970.

The Radeon HD 8970 (OEM) has 2048 Shader Processing Units and the Radeon R9 280X Crossfire has 4096. However, the actual shader performance of the HD 8970 is 1610. The R9 280X having 2486 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 280X delivers a massively smoother and more efficient experience when processing graphical data than the HD 8970.

The Radeon HD 8970 (OEM) requires 250 Watts to run and the Radeon R9 280X Crossfire requires 550 Watts. We would recommend a PSU with at least 600 Watts for the HD 8970 and a PSU with at least 1000 Watts for the R9 280X. The R9 280X requires 300 Watts more than the HD 8970 to run. The difference is significant enough that the R9 280X may have an adverse affect on your yearly electricity bills in comparison to the HD 8970.

GPU Mini Review

Mini ReviewOverview
Radeon HD 8970 (OEM) is an OEM only, High-End Graphics Card based on the First Revision of the Graphics Core Next (GCN) Architecture.

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.

GPU
It equips a GPU Codenamed Tahiti XT which has 32 Compute Units activated and thus offers 2048 Shader Processing Units, 128 TMUs and 32 ROPs. The Central Unit is clocked at 925MHz.

Memory
The GPU accesses a 3GB frame buffer of fast GDDR5, through a 384-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The Memory Clock Operates at 1375MHz.

Power Consumption
With a rated board TDP of 250W, it requires at least a 600W PSU with one available 6-pin and one available 8-pin connectors.

Performance
Radeon HD 8970 (OEM) is a Direct Rebrand of Radeon HD 7970 and performs exactly like it.

System Suggestions
Radeon HD 8970 (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.
Radeon R9 280X Crossfire is a solution of two Radeon R9 280X put together using AMD'S Crossfire technology.
Check the page of Radeon R9 280X to know more about its chip.
Crossfire relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Benchmarks indicate the performance is overall, is up to 60% better than a single Radeon R9 280X performing by itself but at times (depending whether or not the 3D game supports crossfire or in the graphics driver) it performed worse than a single Radeon R9 280X. Expect this combination to draw up to 550 Watt though the average power consumption should be slightly lower.
Even the most demanding games will run at the highest settings.
