AMD announced two of its first Vision A-Series accelerated processing units (APUs) for desktops today. Built in the socket FM1 package, the A6-3650 and A8-3850 are fabricated on the 32 nm HKMG process. Both pack four x86-64 cores, and while the A6 has 320 stream processors in the GPU component, the A8 has 400 of them. Both chips have 4 MB of cache, dual-channel DDR3-1866 MHz IMCs, and PCI-Express 2.0 hubs to drive discrete graphics. The AMD A8-3850 has its four x86-64 cores clocked at 2.90 GHz, with the Radeon HD 6550D GPU engine clocked at 600 MHz. This chip has a TDP of 100W, it is priced at US $135. The AMD A6-3650 has its CPU component clocked at 2.60 GHz, and Radeon HD 6530D GPU engine clocked at 443 MHz. This chip goes for US $115. With these two, AMD is targeting higher models of Sandy Bridge-based Pentium Dual-Core and Core i3 Sandy Bridge chips. Both will be available in stores by July 3.
