What the A6 PRO-7400B is
The A6 PRO-7400B is a fast dual core Kaveri PRO APU on Socket FM2+ for business towers. It runs 2 cores and 2 threads at 3.5 GHz base with turbo to 3.9 GHz. One megabyte of L2 cache covers office apps. Power is 65 W on 28 nm from July 2014. Business firmware adds manageability.
High clocks suit single thread office work with security overhead. Turbo to 3.9 GHz matches retail tuning bursts at stock settings. Radeon R5 with 4 GPU cores at 756 MHz drives business monitors. The 65 W envelope fits standard towers.
DDR3-1866 over two channels feeds cores and graphics. ECC is not supported. Buyers pick the PRO-7400B where fast business dual threads with R5 must run managed fleets.
Socket and motherboard compatibility
The PRO-7400B fits Socket FM2+ on business FM2+ boards. PRO firmware carries manageability features for fleets. DDR3-1866 DIMMs match stock turbo. Consumer boards boot it without management tools.
Dual channel pairs help R5 presentations. The Socket vs chipset: what decides whether a CPU works guide covers AMD pairing. FM2 boards never accept Kaveri.
Memory, PCIe and cooling
DDR3-1866 over two channels suits business towers. Standard images cover office duty. Fast pairs help R5 graphics minimums.
PCIe 3.0 with 16 lanes from the APU feeds low profile slots. Most fleets stay integrated. SSDs lift feel on high base clocks.
Cooling uses 65 W business coolers. The locked multiplier keeps thermals steady.
Upgrade paths
On the same socket, the AMD A4 PRO-7350B at 3.4 GHz below saves cost with slower graphics, while the AMD A6-7400K at the same clocks covers retail tuning. All share FM2+ boards.
Newer PRO refresh parts cover later fleets. The PRO-7400B holds fast business dual thread Kaveri duty.
