What the PRO A4-8350B is

The PRO A4-8350B brings Kaveri to FM2+ for business towers with DDR3. It launched on September 29, 2015 with a 3.5 GHz base and up to 3.9 GHz boost at 65 W. AMD targets office fleets that need two 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. DDR3-1866 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, which cuts validation time for system updates. The 65 W rating fits standard towers. Lenovo lists the part in ThinkCentre M79 towers with R5 graphics.

Socket and motherboard compatibility

The PRO A4-8350B fits Socket FM2+ on FM2+ boards with DDR3 slots. Business A78 boards list PRO APUs with display outputs. Consumer boards may boot it where listed, but management needs business firmware.

2015 BIOS builds carry Kaveri 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 for dual monitors.

Memory, PCIe and cooling

DDR3-1866 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 where fleets run daily. ECC is not offered.

Upgrade paths

On the same socket, the AMD Athlon X4 830 gives four cores without graphics for headless nodes. The AMD A8-7650K moves to four cores with R7 graphics for faster desks. Both share FM2+ boards.

Godavari PRO A6-8550B steps up to newer cores where listed. It needs board checks for support.

Past FM2+ business towers move to AM4 Ryzen PRO. The PRO A4-8350B covers DDR3 offices where two cores with graphics must deploy with fleet drivers.
