AMD Boxed A4 3400 2.7GHz Desktop Processor

AMD introduced its first dual-core Llano APUs: the A4-3400 and A4-3300. These APUs have only 758M active transistors, a bit over half of the transistors in the bigger quad-core alternatives. AMD originally indicated that it would have a separate die for the dual-core APUs but it's unclear whether or not the first A4s will be on the new die or simply used a fused off quad-core Llano. TDP is kept at 65W and there's no Turbo Core supported on either A4 model. These GPUs only have 160 Radeon cores, which should still result in performance competitive with Intel's Sandy Bridge Pentiums based on what we've seen from the 320 core version of the GPU. If we assume linear scaling with core count there shouldn't be many (any?) areas where the Radeon HD 6410 is slower than the SNB Pentium's HD Graphics GPU.

These A4s will work in all existing Socket-FM1 motherboards. Although not listed in the table above, only the A6 and above officially support DDR3-1866. The A4s only support up to DDR3-1600. This isn't too big of a deal as we found in our investigation: DDR3-1600 is the sweet spot for Llano APU performance.
