Socket FT3 socket: CPUs, chipsets and cooler fit

Who Socket FT3 serves

Socket FT3 belongs in fanless tablets, small notebooks, micro servers and embedded boards where 9 W to 25 W matters. Kyoto Opteron parts target cold storage and communications gear with ECC memory. Steppe Eagle parts such as X2170 target industrial controllers and edge boxes that need four x86 cores with graphics on one board.

Boards pair the SoC with SODIMM or UDIMM slots for DDR3, plus SATA and USB from the integrated hub. Display outputs drive control panels directly from Radeon graphics, so many designs run without a discrete card. Power input stays modest, which suits DIN rail and compact chassis builds.

Memory and PCIe

Memory support covers DDR3 SODIMM and UDIMM modules up to 1600 MT/s across one or two channels. ECC works on selected embedded boards for storage nodes. Matched pairs lift graphics and file throughput where bandwidth matters.

PCIe arrives as version 2.0 with up to 8 lanes from the SoC, wired as one x4 graphics link plus configurable general purpose ports. Boards split lanes between SATA controllers, Ethernet and Mini PCIe slots per manual. Gen3 cards run at Gen2 speed here, which still covers control and storage traffic.

Identification is simple in maker documents: package reads BGA769 and size reads 24.5 mm x 24.5 mm. That line separates FT3 from AM1 desktop parts at 721 pins and from FP4 mobile parts at 769 contacts with a different ball map.
