What the Core M-5Y31 is
The Core M-5Y31 steps up Broadwell-Y turbo on BGA 1234 for premium thin devices. It runs 2 cores and 4 threads at 900 MHz base with turbo to 2.4 GHz. Four megabytes of Smart Cache cover multitasking. Power is 4.5 W on 14 nm from October 2014.
The 2.4 GHz turbo smooths foreground work over 5Y10 class parts at the same power. HD Graphics 5300 up to 850 MHz lifts video calls. Battery life still leads in sealed bodies. The soldered package means buyers choose the device once.
LPDDR3 and DDR3L over two channels to 16 GB feed cores and graphics. The 5Y31 covers autumn premium detachables where turbo matters more than base clocks.
Socket and motherboard compatibility
The 5Y31 solders to BGA 1234 with fanless cooling for 4.5 W. No later swap exists. Premium bodies pair it with fast SSDs. Soldered LPDDR3 locks memory size.
SoC I/O serves peripherals. The LGA, PGA and BGA: CPU package types explained guide explains soldered limits.
Memory, PCIe and cooling
LPDDR3-1600 and DDR3L-1600 over two channels to 16 GB suit premium thin bodies. Dual channel pairs feed HD 5300. Fast storage covers app launches.
PCIe 2.0 with 12 lanes serves SSDs and radios. Thin SSDs match the power budget. Most builds stay integrated.
Cooling is passive for 4.5 W. Turbo to 2.4 GHz needs cool bodies. Skin limits trim sustained bursts.
Upgrade paths
On the same socket, the Intel Core M-5Y10c at lower turbo below saves cost, while the Intel Core M-5Y51 at 1.1 GHz to 2.6 GHz above adds base. All share BGA-1234.
Skylake-Y parts cover newer thin duty. The 5Y31 holds mid turbo Core M value.
