AMD is planning to announce next-generation Carrizo APUs in March 2015 to replace its existing Kaveri APUs for the mainstream performance notebook segment, according to soutces from Taiwan.

AMD wil release Carrizo-L APUs for the entry-level notebook segment in December 2014 at the earliest to challenge Intel's Pentium and Celeron processors, Digitimes.com reports.

The Carrizo 28nm processors will feature quad-core architecture and an Excavator Core. The APUs will also support DDR3-2133 memory, Windows 10/Windows 8.1, Ubuntu and SLED operating systems. We've been also hearing that that Carrizo would fit in existing Socket FM2+ motherboards.

The Carrizo-L APUs will replace AMD's existing Beema and Mullins APUs for entry-level notebooks and tablets.
