What the A4-4020 is
The A4-4020 is a value Richland dual core on Socket FM2 for cheap office desktops. It runs 2 Piledriver cores and 2 threads at 3.2 GHz base with turbo to 3.4 GHz. One megabyte of L2 cache covers office tasks. Power is 65 W on 32 nm SOI from March 2014.
Modest clocks with integrated graphics suit terminals and school machines. Turbo covers foreground bursts. The 65 W envelope fits slim cases with stock cooling. The socketed package swaps across FM2 boards and most FM2+ boards.
Radeon HD 7480D drives office monitors for video and presentations. DDR3-1333 over two channels feeds cores and graphics. Buyers pick the 4020 where the cheapest Richland socketed box must still run Windows.
Socket and motherboard compatibility
The 4020 fits Socket FM2 on A55, A75 and A85X boards. Most Socket FM2+ boards also boot Richland after a BIOS check. The 65 W rating suits every FM2 VRM design. DDR3-1333 DIMMs match stock operation.
Two DDR3 channels serve the APU. The Socket vs chipset: what decides whether a CPU works guide covers AMD chipset pairing. FM1 boards never accept Richland chips.
Memory, PCIe and cooling
DDR3-1333 over two channels suits value office desktops. One 4 GB DIMM covers terminals. Dual channel pairs help HD 7480D video.
PCIe 2.0 from the APU wires one graphics slot for low profile cards. Most builds stay on integrated graphics. SATA SSDs lift fixed feel the most.
Cooling uses the 48 by 96 mm FM2 mount with stock 65 W coolers. Quiet profiles suit offices. Small cases need intake clearance.
Upgrade paths
On the same socket, the AMD A4-7300 at 3.8 GHz to 4.0 GHz with HD 8470D above adds big clocks, while FM2+ Kaveri dual cores cover newer builds. All share FM2 boards where listed.
FM2+ replaced the platform with Steamroller. The 4020 holds value Richland duty where price decides.
