The Central Unit runs at 1025MHz.

Memory: Speed
Each GPU is equipped with fast GDDR5 and Accesses the Frame Buffer through a 512-bit Memory Interface. The Memory Clock Operates at 1500MHz.

Memory: Frame Buffer
The GPU can fill up a Memory Pool of up to 8GB. Under most circumstances, this only proves useful in certain 3D Games whose Settings Require Large Amounts of Memory.
However, because the GPU itself is too weak to work under other circumstances in which 8GB of Memory are needed - such as 4K Gaming, a Large Frame Buffer is mostly a Gimmick.

Power Consumption
Power Consumption is around 550W.

Performance
Benchmarks Indicate a 1% Performance Boost over the Reference Radeon R9 390 Crossfire.

System Suggestions
We recommend a High-End Processor and 16GB of RAM for Optimal Performance.
