What the A4 Micro-6400T is
The A4 Micro-6400T is a quad core Mullins tablet APU on Socket FT3 for hybrids that need four threads. It runs 4 Puma+ cores and 4 threads at 1.0 GHz base with bursts to 1.6 GHz. Two megabytes of L2 cache cover tablet multitasking. Power is 4.5 W with a 2.8 W SDP rating on 28 nm from April 2014.
Four cores double threads over the E1 Micro dual core at similar power. Low base clocks protect battery while bursts cover UI work. The 128 shader R3 graphics at 350 MHz play video smoothly. The soldered package means the hybrid choice locks everything.
DDR3L-1333 over one channel feeds cores and graphics. The A4 Micro-6400T covers convertibles where Mullins quad threads must fit 4.5 W.
Socket and motherboard compatibility
The A4 Micro-6400T solders to the board on Socket FT3 and cannot be replaced. Hybrid memory and SSD lock at purchase. Boards wire small batteries with eMMC or SSD options.
FT3 tablets share SoC I/O. The LGA, PGA and BGA: CPU package types explained guide explains soldered limits.
Memory, PCIe and cooling
DDR3L-1333 over a single channel suits hybrids with SSDs. Low speed memory saves power. Single channel is fixed.
PCIe 2.0 with up to 8 lanes from the SoC serves storage and radios. Convertibles use little wired expansion. R3 graphics cover detachable displays.
Cooling is passive for 4.5 W with skin limits. Bursts trim under sustained load. Thin hybrids throttle first.
Upgrade paths
On the same socket, the AMD E1 Micro-6200T at dual core below saves cost, while the AMD A10 Micro-6700T at 1.2 GHz to 2.2 GHz with R6 graphics above adds speed. All share FT3 boards.
Newer tablets moved past Mullins. The A4 Micro-6400T holds quad tablet duty at 4.5 W.
