We saw some socketed Kabini motherboards at CES this year from MSI, and Chinese VR-Zone has published some interesting numbers regarding processors that are predicted to be on sale in March 2014.

Aside from the soldered Kabini we already have in, the socketed versions are aimed more towards the consumer range than the industrial PC  or embedded lines that commonly utilise soldered on CPU/APUs.  They will be based on the Jaguar CPU core design, which also means being limited to 64-bit single channel DDR3 memory.  The focus of Kabini in this case is the need is for something just to process primarily in-cache data.

The APUs are also slated by VR-Zone to use GCN architecture for the integrated graphics portion.  The main competition is from Intel’s Bay-Trail-D range of processors, which we have seen samples being announced.  While the standard FS1b socket for Kabini is current, the rumor extends that this will be called AM1 for the new socketed APUs.

The current rumoured line up sits as:

AMD AM1 Kabini AMD FT3 Kabini
  A6-5350 A4-5150 E2-3850 E1-2650 A6-5200 E1-2500
Cores / Threads 4 / 4 4 / 4 4 / 4 2 / 2 4 / 4 2 / 2

L2 Cache 2MB 2MB 2MB 1MB 2MB 2MB
TDP 25 W 25 W 25 W 25 W 25 W 25 W

As we can see, the desktop related socketed parts are closely related to those already in systems using a BGA interface (FT3).

The main advantage AMD has with socketed Kabini is that Intel’s socketed offering in this range comes down to low powered –T and –TE processors from Haswell, which are expensive but offer higher performance, which is not always needed.  Intel’s main low power Atom/Bay Trail range is still all BGA, meaning that the socketed Kabini route has potential for upgrades should AMD expand the processor line. The use of GCN with Kabini also offers up on the compute front, something which the Intel Haswell/Avoton line lack and the BayTrail-D line might fall up short.

What would be exciting to see is if AMD plan to keep this socket for Beema (Beema replaces Kabini in 2014, Mullins replaces Temash) which also provides a further upgrade path.
