In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 390X PowerColor Devil 8GB Edition are massively better than the AMD Radeon R9 370 (OEM).

The R9 390X has a 175 MHz higher core clock speed and 112 more Texture Mapping Units than the R9 370. This results in the R9 390X providing 134.4 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 R9 390X has a 175 MHz higher core clock speed and 32 more Render Output Units than the R9 370. This results in the R9 390X providing 40.8 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 R9 390X was released less than a year after the R9 370, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The R9 390X has 6144 MB more video memory than the R9 370, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the R9 390X also has superior memory performance overall.

The R9 390X has 211.2 GB/sec greater memory bandwidth than the R9 370, which means that the memory performance of the R9 390X is massively better than the R9 370.

The Radeon R9 390X PowerColor Devil 8GB Edition has 2816 Shader Processing Units and the Radeon R9 370 (OEM) has 1024. However, the actual shader performance of the R9 390X is 2633 and the actual shader performance of the R9 370 is 849. The R9 390X having 1784 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 390X delivers a massively smoother and more efficient experience when processing graphical data than the R9 370.

The Radeon R9 390X PowerColor Devil 8GB Edition requires 275 Watts to run and the Radeon R9 370 (OEM) requires 150 Watts. We would recommend a PSU with at least 750 Watts for the R9 390X and a PSU with at least 500 Watts for the R9 370. The R9 390X requires 125 Watts more than the R9 370 to run. The difference is significant enough that the R9 390X may have an adverse affect on your yearly electricity bills in comparison to the R9 370.

Benchmarks Indicate a 2% Performance Boost over the Reference Radeon R9 390X 8GB.
Radeon R9 370 (OEM) is, an OEM only, Performance Graphics Card based on the first revision of the Graphics Core Next 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 PRO which is was previously used on Radeon HD 7850. It offers 1024 Shader Processing Units, 64 TMUs and 32 ROPs. The central unit runs at 925MHz and goes up to 975MHz, in Turbo Mode.

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 1400MHz.

DirectX 12.0 Support (11.0 Hardware Default) and support for Crossfire, Mantle, PowerTune, Eyefinity, ZeroCore, HD3D, App Acceleration and other technologies.

Power Consumption
With a rated board TDP of 150W, it requires at least a 500W PSU with two available 6-pin connectors.

Radeon R9 370 (OEM) is essentially a fast Radeon R7 265. Therefore, its performance stands somewhere between Radeon R7 265 and the faster Radeon R7 270.

System Suggestions
We recommend a modest Quad Core Processor (Intel Core i5 Quad Core/AMD FX Quad Core) and 8GB of RAM for a system with Radeon R9 370 (OEM).
