Die shot of the Llano architecture


The A4-3400 has a little over half the active transistors available on the whole Llano die, having the Radeon core count reduced to 160 from 400 and only two active CPU cores, one would assume that these reductions would be enough however AMD sought to nerf the A4 even more by halving the L2 cache per core from 1MB to 512KB. The IMC is stepped down a gear to natively support memory with a frequency of 1600Mhz, which isn't too much of an issue as the 160 Radeon cores will be throwing around significantly less data than 320 or the full 400 of them. These reductions bring the A4-3400 APU in with a 65W TDP which means it won't be getting too hot under the collar and thus small, low profile cooling is adequate enough.
