What the PRO A6-8550B is
The PRO A6-8550B brings Godavari to FM2+ for business towers with DDR3. It launched in September 2015 with a 3.7 GHz base and up to 4.0 GHz boost at 65 W. AMD targets office fleets that need two fast cores with graphics and stable drivers.
One megabyte of L2 supports office multitasking without L3. The high base clock keeps business apps responsive. Two threads cover foreground documents plus security agents.
Radeon R5 graphics handle office displays and video conferencing. The process is 28 nm. The multiplier is locked on PRO parts. DDR3-2133 in two channels feeds CPU and graphics with period memory.
IT teams value the PRO label for image stability across quarters. The same driver pack covers many desks. The 65 W rating fits standard towers. Lenovo lists the part in ThinkCentre M79 towers with R5 graphics.
Socket and motherboard compatibility
The PRO A6-8550B fits Socket FM2+ on FM2+ boards with DDR3 slots. Business boards list PRO APUs with display outputs. Consumer boards may boot it where listed, but management needs business firmware.
2015 BIOS builds carry Godavari IDs on FM2+ boards. AM4 boards cannot take this PGA chip. The Socket vs chipset: what decides whether a CPU works guide covers matching.
Single socket business towers are the target. Another FM2+ APU can follow on the same board where listed. Display outputs include HDMI and DisplayPort.
Memory, PCIe and cooling
DDR3-2133 in two channels suits business desktops with SSDs. Matched pairs help R5 graphics during conferencing. Start with 8 GB for office fleets.
PCIe 3.0 from the APU covers board devices per FM2+ layout. Integrated R5 leaves the main slot free for NICs. Chipset lanes add storage and USB.
Cooling uses the FM2+ mount from the CPU cooler compatibility by socket guide. A 65 W stock cooler runs quietly. Keep filters clean. ECC is not offered.
Upgrade paths
On the same socket, the AMD PRO A4-8350B steps down to Kaveri cores for entry desks. The AMD PRO A8-8650B moves to four cores with R7 graphics for faster fleets. Both share FM2+ boards.
Home users can pick A6-7470K without PRO firmware for similar speed.
Past FM2+ business towers move to AM4 Ryzen PRO. The PRO A6-8550B covers DDR3 offices where two fast cores with graphics must deploy.
