What the A4-3320M is
AMD A4-3320M is a dual core Llano mobile APU that AMD released in December 2011 for socketed laptops. It uses the Stars K10 core design on a 32 nm process, running at 2.0 GHz base with Turbo Core to 2.6 GHz. The cache is 2 MB of L2 with 1 MB per core. Power is 35 W. Graphics come from AMD Radeon HD 6480G with 240 shaders at a fixed 444 MHz.
The late 2011 refresh lifts base by 100 MHz and turbo by 100 MHz over the A4-3300M at the same power and graphics. Bursty single thread tasks reach 2.6 GHz while threaded loads share the higher base. Threads equal cores at 2.
Mainstream laptops pair it with DDR3-1333 SODIMMs and a single fan. Boards need a BIOS new enough to list this December model. The How to find your CPU socket type guide shows how to confirm the socket.
Socket and motherboard compatibility
The A4-3320M fits Socket FS1 with 722 contacts in pin grid form. Hudson A60M and A70M boards carry it where the BIOS lists the exact A4-3320M string. Late 2011 firmware matters more than the chipset name.
At 35 W any Socket FS1 heatsink of that class covers it. The CPU cooler compatibility by socket guide notes laptop heatsinks stay board specific.
Memory, PCIe and cooling
Memory support is DDR3-1333, two channels. Two matched SODIMMs feed cores and shared graphics. DDR3-1600 stays an MX feature.
PCI Express is revision 2.0 from the APU for Wi-Fi and storage. Most builds stay on integrated graphics.
Cooling is board specific for 35 W. Cleaning holds the 2.6 GHz burst longer.
Upgrade paths
On Socket FS1 the A4-3320M can move to faster A4, A6 or A8 parts where access and BIOS allow it. Memory and storage carry over. A slower comparison at the same power is AMD A4-3300M on the same socket.
A platform move means a new laptop. Keep the current body for office duty after a wipe.
