Apparently, mobile platform has become AMD's recent target. Relevant products are coming out earlier too.
In 2012, we will see new generation products, again, as usual. The attraction point is enhanced Bulldozer APU.
First, at the highest end, AMD added new flagship processor (New market line), codenamed Trinity.
The CPU is powered by enhanced Bulldozer core, Piledriver. It has 4 cores (2 modules). For the GPU part, it uses the VLIW4 architecture from HD6900. but the stream processors are still unknown. This flagship product's TDP will reach 60W. Sounds like it is ridiculous, but compared to Intel's flagship, it is only 5W higher. The increment is still acceptable, but for sure, it will have much stronger processor and graphical performance.
Next, A8-3500M, A6-3400M, A4-3300M will be replaced by Trinity, Weatherford, Richlard. They are still powered by 4 cores, 4 cores, and 2 cores respectively. Since they are based on Piledriver core, they will have 2 modules, 2 modules, 1 module respectively. The GPU are seperated into Highest Performance, High Performance, Mainstream. The difference is number of stream processors and clock speed. All processor is these series has 45W or 35W TDP, same with current APU.
E2-3200M will not evolve to Piledriver, but it uses enhanced Bobcat core instead. It is codednamed as Wichita, comes with 4 cores, discrete class GPU (Maybe using the high end VLIW5 architecture) and TDP is decreased to 20W.
Current Bobcat based low power E/C series processors will replaced by Wichita, Krishna, all powered by Enhanced Bobcat core. They comes with 2 cores, simpler GPU. TDP of them are 20W and 8W respectively. The earlier 1 is slightly increased, and the last one is decreased slightly.
Until now, no news on AMD's new APU will use what naming convention. If follow the trend, it will be Ax-4000. If not, B, D, F series (

).
