Radeon HD 8870 (OEM) Game Requirement Analysis
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.
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.
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.
