Radeon HD 8790M Game Requirement Analysis
Radeon HD 8790M is a Fast-Middle-Class Mobile Graphics Card based on the Second Revision of the GCN Architecture.
The GCN 1.1 Release adds support for AMD's TrueAudio Technology which does calculations of audio effects "better" than the CPU and further improves the Powertune Technology.
It equips a GPU codenamed Mars XTX which has 6 Compute Units activated and thus offers 384 Shader Processing Units, 24 TMUs and 8 ROPs. The Central Unit Initially Operates at 850MHz and goes up to 900MHz, in Turbo Mode.
The GPU accesses a 2GB frame buffer of fast GDDR5, through a 128-bit memory interface. The size of the frame buffer is adequate. The memory clock operates at 1000MHz.
DirectX 11.0 Support (11.0 Hardware Default) and support for Crossfire, PowerTune Technology, Eyefinity, App Acceleration, HD3D, ZeroCore Power and other technologies.
With a rated board TDP of 35W, it is suited for 15" or larger laptops.
Gaming benchmarks put its performance slightly below NVIDIA's GeForce GTX 660M.
We recommend a Decent Processor (Intel Core i5 Mobile) and 8GB of RAM for a system with Radeon HD 8790M.
