What the A10 PRO-7850B is
The A10 PRO-7850B tops business Kaveri on Socket FM2+ for workstation fleets. It runs 4 cores and 4 threads at 3.7 GHz base with turbo to 4.0 GHz. Four megabytes of L2 cache cover design apps. Power is 95 W on 28 nm from July 2014. The PRO tag adds manageability and lifecycle coverage.
Top base clocks in the PRO line suit single thread CAD with background services. Radeon R7 with 8 GPU cores at 720 MHz drives business monitors with Eyefinity options. Four threads handle office multitasking with security overhead. The 95 W envelope needs tower business cooling.
DDR3-2133 over two channels feeds cores and graphics. Business stability suits fleets. Buyers pick the PRO-7850B where top managed Kaveri threads with full R7 must run standard images.
Socket and motherboard compatibility
The PRO-7850B fits Socket FM2+ on business FM2+ boards with PRO firmware. The 95 W rating needs solid VRMs. DDR3-2133 DIMMs match stock turbo. Consumer boards boot it without management tools.
Dual channel fast DDR3 serves fleet apps. The Socket vs chipset: what decides whether a CPU works guide covers AMD pairing. FM2 boards never accept Kaveri.
Memory, PCIe and cooling
DDR3-2133 over two channels suits business towers. Standard images cover design duty. Fast pairs help R7 presentations.
PCIe 3.0 with 16 lanes from the APU feeds workstation cards or NVMe adapters. Most fleets stay on R7 graphics. SSDs lift feel on high base clocks.
Cooling uses 95 W business towers. Sustained all core turbo needs airflow. The locked multiplier keeps fleet thermals steady.
Upgrade paths
On the same socket, the AMD A10 PRO-7800B at 3.5 GHz with 65 W tuning below saves power, while the AMD A10-7800 matches consumer builds. All share FM2+ boards.
Newer PRO refresh parts cover later fleets. The PRO-7850B remains the business Kaveri clock lead.
