What the A6-3650 is
AMD A6-3650 is a quad core Llano APU that AMD released in June 2011 for socketed desktops. It uses the Stars K10 core design on a 32 nm process, running at 2.6 GHz with no turbo. The cache is 4 MB of L2 with 1 MB per core. Power is 100 W. Graphics come from AMD Radeon HD 6530D with 320 shaders at 443 MHz.
High fixed clocks with four cores suit threaded home work that never uses turbo. The 100 W budget buys 500 MHz over the 65 W A6-3600 at the cost of heat and a larger cooler. Threads equal cores at 4.
Towers pair it with A55 or A75 boards, 4 GB to 8 GB of DDR3 and a SATA drive. Fixed 2.6 GHz clocks keep behavior predictable. The How to find your CPU socket type guide shows how to confirm the socket.
Socket and motherboard compatibility
The A6-3650 drops into Socket FM1 on A55 and A75 boards. Early FM1 boards from the June 2011 launch accept it with a shipping BIOS. DDR3 modules match stock operation.
Power at 100 W needs a standard tower board with a full size cooler. Slim 65 W boards may not cover it. The CPU cooler compatibility by socket guide explains the shared AMD mount.
Memory, PCIe and cooling
Memory support is DDR3 up to 1866 MT/s, two channels. Two matched modules feed four cores and shared graphics. Faster DIMMs help the graphics block.
PCI Express is PCIe 2.0 from the APU for one graphics slot. Most builds stay on integrated graphics alone.
Cooling follows the 100 W rating with a larger stock heatsink or tower cooler. Fair case airflow holds the fixed 2.6 GHz rate.
Upgrade paths
On Socket FM1 the A6-3650 can move to the unlocked A6-3670K on the same board for multiplier headroom. Memory and storage carry over. A lower power quad reference is AMD A6-3600 on the same socket.
A platform move to Socket FM2 needs a new board while DDR3 often carries over.
Frequently asked questions
