- ATI PowerPlay™
Technology
ATI PowerPlay™ Technology delivers high performance when needed
and conserves power when the demand on the graphics processor is
low.
- Energy Efficient
Manufacturing Process
Second generation 55nm chip uses the industry’s most energy
efficient manufacturing process.
The HD4870 features 512MB of GDDR5 memory.
There aren't too many folks in town making GDDR5 right now, but
Qimonda has partnered with AMD to provide the chips for launch of
the 4870. AMD has chosen to go with a 256-bit memory bus,
hopefully going with GDDR5 memory that's all they'll need.
