Radeon HD 8770M Game Requirement Analysis
Radeon HD 8770M 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 XT which has 6 Compute Units activated and thus offers 384 Shader Processing Units, 24 TMUs and 8 ROPs. The Central Unit Initially Operates at 775MHz and goes up to 825MHz, 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 1125MHz.
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 20W, it is suited for 13" or larger laptops.
Gaming benchmarks put its performance somewhat above NVIDIA's GeForce GT 645M.
We recommend a Decent Processor (Intel Core i5 Mobile) and 8GB of RAM for a system with Radeon HD 8770M.
