AMD A6-3650 Llano APU Performance Review

Article Index:   

Desktop Llano APUs, like the A6-3650 we'll be featuring here use AMD’s FM1, 40mm x 40mm, lidded packaging as opposed to the FS1, 35mm x 35mm, lidless packaging of the mobile variants.


AMD A6-3650 APU In a Hard Candy Shell

While Llano APUs look very similar to current Phenom II and Athlon II processors from the top, thanks to the similar lid and integrated heat spreader installed on the chips, they use a completely different pin configuration and also a different socket. Desktop Llano APUs have 905 pins on their underside whereas socket AM3 Phenom II and Athlon II processors have 939 pins.

 
AMD A6-3650 CPU-Z and GPU-Z Details

The AMD A6-3650 APU has a default CPU clock speed of 2.6GHz (26 x 100MHz). It has four x86 cores each with 128 KB L1 Cache (64KB Instruction, 64KB Data) and 1MB of L2 per core—no L3 cache is present. Current Phenom II processors have similar L1 configurations, but only half the L2, plus a large 6MB L3. The larger L2 should help mitigate the loss of the L3, along with some other improvements to the cores. The 32mn “Stars” derived cores in Llano have improved schedulers and branch predictions units, along with some other low-level tweaks that result in an approximate 6% improvement in IPC performance over current-gen Phenom II processors.

There’s not much to see with regard to the integrated Radeon HD 6530D GPU core in the GPU-Z screenshot that we haven’t already talked about. To reiterate, the GPU core runs at 443MHz and has 320 shader ALUs arranged in 4 SIMDs. The fifth SIMD that’s active in A8-series APUs is disabled on the A6-3650, and other A6-series parts.
