The so-called Accelerated Processing Units (APUs) are designed for use in low-cost netbooks and thin laptops, targeting Intel's Atom.
Launched earlier this year, AMD said it shipped five million C- and E-series APUs in the second quarter alone. Now, they're being updated to offer improved HD graphics and performance, and support for upgraded DisplayPort connections.
Power efficiency has also been improved, with battery life on a test device extended by up to four hours to a full 12 for the C-Series and 10.5 hours for the E-Series - based on AMD's own tests with a netbook containing a six-cell 62.16Wh battery.
The E-Series will also get DDR3 1,333Mhz memory support to boost performance and video playback, as well as HDMI 1.4a - the spec that offers 3D support.
The new APUs are available from today, AMD said. There was no update announced for the desktop-focused A-Series.
