AMD Kaveri Successor Carrizo to get DDR4 support and FCH
Rumors on AMDs upcoming Carrizo APUs have surfaced. The Carrizo series should succeed Kaveri in 2015. The APU should be able to support both DDR3 and DDR4 memory according to a leaked slide. APUs for laptops will also get integrated IO connectivity. With Carrizo AMD will transfer from Steamroller CPU cores towards Excavator-cores.
The Excavator-cores will get the same extensions that Intel's haswell already have like AVX2, bmi2, movbe en rdrand. Interesting to see is that Carrizo will still be baked on a 28nm fabrication node. The GPU part of the APU will be based on Volcanic islands GCN 2.0 just like Kaveri. As stated the memory controller will be able to support both DDR3 and DDR4 memory. With the soldered SoC versions for laptops the APUs will get an integrated FCH that will provide IO with two SATA 6Gbit ports, four USB 3.0 ports and eight USB 2.0 ports. On desktops the Carrizo-chips will find thay way to FM2+ sockets. The internal FCH will then be disabled allowing a Southbridge chip to gain more sata ports etc.
It isn't clear if motherboard / desktop based Carrizo APUs also will support DDR4, but it would be highly unlikely. Interesting to see is that the number of PCI Express lanes has been reduced from 24 towards 16.

Not sure what your expectations are from an APU.
But for a low-budget low-powered gaming rig that can actually play games, AMD's APUs are still the only way to go.

Intel produces mostly APU's for their consumer processor lines. Celeron, Pentium, i3, i5 and mainstream i7 processors are all technically APU's. Being an APU really isn't an excuse for not pushing CPU performance forward.

Maybe, but I would sacrifice a little CPU performance for a better iGPU in budget builds any day.
iGPUs are stressed to the max in almost any game on modern screens while most daily tasks don't push the CPU to its limits.

Hopefully Carrizo will bring bigger CPU performance gains.....
Kaveri is quite a bit faster clock-for-clock than the previous ones.

Exactly. AMD's IGPs utterly annihilate Intel

I think intel have gotten quite complacent really.
With regards to the PCIe lanes, that is odd, unless some are going to be wired to the new PCH on chip, though IIRC you still get some off the SB anyway.
