The series features AMD’s second generation ATI PowerPlay™ technology which allows for automatic power adjustments based on the activity of the graphics processing unit (GPU), resulting in significant power savings when the GPU is idle. The press release accompanying the release emphasizes how little power these new cards draw:īoth the ATI Radeon HD 4670 and ATI Radeon HD 4650 deliver substantial gaming horsepower with minimal power draw – the ATI Radeon HD 4670 operating at under 60 watts and the ATI Radeon HD 4650 operating under 50 watts under full load – eliminating the need for additional power connectors and making installation a cinch.īuilt with efficiency, scalability and performance in mind, the ATI Radeon HD 4600 series sets a new performance-per-watt standard for mainstream graphics products, thanks to the enhanced bandwidth of DDR3, new power management capabilities that provide greater performance and efficiency, and 55nm technology. Note: A version of the HD 4670 with 1GB of memory is scheduled to be released later this month.
