What the A6-3400M is
AMD A6-3400M is a quad core Llano mobile APU that AMD released in June 2011 for socketed laptops. It uses the Stars K10 core design on a 32 nm process, running at 1.4 GHz base with Turbo Core to 2.3 GHz. The cache is 4 MB of L2 with 1 MB per core. Power is 35 W. Graphics come from AMD Radeon HD 6520G with 320 shaders at a fixed 400 MHz.
Low base clocks with a tall 900 MHz turbo range define daily behavior. All core loads sit near 1.4 GHz inside 35 W, while lightly threaded bursts reach 2.3 GHz. The 320 shader block doubles dual core graphics for laptop video playback.
Mainstream laptops pair it with DDR3-1333 SODIMMs and a single fan. Four threads at 35 W cover office multitasking in 15 inch bodies. The How to find your CPU socket type guide shows how to confirm the socket.
Socket and motherboard compatibility
The A6-3400M fits Socket FS1 with 722 contacts in pin grid form. Hudson A60M and A70M boards carry it with the BIOS listing the exact A6-3400M string. Early Sabine boards accept it with a shipping BIOS.
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 four threads and shared graphics. DDR3-1600 stays an MX feature.
PCI Express is revision 2.0 from the APU for Wi-Fi, storage and any discrete GPU. Most builds stay on the HD 6520G alone.
Cooling is board specific for 35 W. The tall turbo range rewards clean airflow with longer 2.3 GHz bursts.
Upgrade paths
On Socket FS1 the A6-3400M can move to faster A6 or A8 APUs where access and BIOS allow it. Memory and storage carry over. A higher base comparison at the same power is AMD A6-3420M on the same socket.
A platform move means a new laptop. Keep the current body for office duty after a wipe.
