What the A6-3620 is

AMD A6-3620 is a quad core Llano APU that AMD released in December 2011 for socketed desktops. It uses the Stars K10 core design on a 32 nm process, running at 2.2 GHz base with Turbo Core to 2.5 GHz. The cache is 4 MB of L2 with 1 MB per core. Power is 65 W. Graphics come from AMD Radeon HD 6530D with 320 shaders at 444 MHz.

The late 2011 refresh adds 100 MHz at both ends over the A6-3600 at the same power and graphics. Four cores with turbo cover threaded home work while bursts keep single thread tasks direct. Contemporary December reports round the graphics to 444 MHz against 443 MHz listings elsewhere.

Home towers pair it with A55 or A75 boards and an SSD for a direct feel. Fixed firmware should carry a BIOS new enough to list this late 2011 model. The LGA, PGA and BGA: CPU package types explained guide places this PGA desktop part against BGA mobile forms.

Socket and motherboard compatibility

The A6-3620 drops into Socket FM1 on A55 and A75 boards. Late 2011 models need a BIOS new enough to list the exact A6-3620 string. DDR3 modules match stock operation.

Power at 65 W suits standard desktop boards. The Socket vs chipset: what decides whether a CPU works guide covers AMD pairing rules.

Memory, PCIe and cooling

Memory support is DDR3 up to 1866 MT/s, two channels. Two matched modules feed four cores and shared graphics.

PCI Express is PCIe 2.0 from the APU for one graphics slot. Most builds stay on integrated graphics.

Cooling follows the 65 W rating with a stock heatsink. The shared AMD mount keeps choice wide.

Upgrade paths

On Socket FM1 the A6-3620 can move to faster quad Llano APUs on the same board. Memory and storage carry over. A slower quad reference on the same socket is AMD A6-3600.

A platform move to Socket FM2 needs a new board while DDR3 often carries over.

Frequently asked questions

What socket does the AMD A6-3620 use?

It uses Socket FM1. Boards need a BIOS new enough to list this late 2011 model.

How is the A6-3620 different from the A6-3600?

Base is 2.2 GHz instead of 2.1 GHz, and turbo is 2.5 GHz instead of 2.4 GHz.

What memory does the A6-3620 use?

DDR3 up to 1866 MT/s, two channels.

Does the A6-3620 need a separate graphics card?

No. Radeon HD 6530D at 444 MHz covers office displays and video.
