What the A8-3500M is
AMD A8-3500M 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 1.5 GHz base with Turbo Core to 2.4 GHz. The cache is 4 MB of L2 with 1 MB per core. Power is 35 W. Graphics come from AMD Radeon HD 6620G with 400 shaders at a fixed 444 MHz.
Four threads with the strongest 35 W graphics of the Llano mobile line cover office work, video and light games without a card. The 400 shader block doubles A6 graphics for display work. Turbo Core lifts bursts to 2.4 GHz while all core loads share the base rate.
Mainstream laptops pair it with DDR3-1333 SODIMMs and a single fan. The 35 W envelope suits 15 inch bodies with standard cooling. The How to find your CPU socket type guide shows how to confirm the socket.
Socket and motherboard compatibility
The A8-3500M fits Socket FS1 with 722 contacts in pin grid form. Hudson A60M and A70M boards carry it with the BIOS listing the exact A8-3500M 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 the 400 shader block. 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 6620G alone.
Cooling is board specific for 35 W. The tall turbo range rewards clean airflow with longer 2.4 GHz bursts.
Upgrade paths
On Socket FS1 the A8-3500M can move to faster A8 parts where access and BIOS allow it. Memory and storage carry over. A higher base comparison at the same power is AMD A8-3520M on the same socket.
A platform move means a new laptop. Keep the current body for office duty after a wipe.
