What the Core M-5Y71 is

The Core M-5Y71 tops Broadwell-Y on BGA 1234 for premium fanless 2 in 1 devices. It runs 2 cores and 4 threads at 1.2 GHz base with turbo to 2.9 GHz. Four megabytes of Smart Cache cover office multitasking. Power is 4.5 W with a 3.5 W SDP rating on 14 nm from October 2014, with 6 W configurable up tuning at 1.4 GHz.

The 2.9 GHz turbo leads all 5Y parts in single thread bursts. HD Graphics 5300 from 300 MHz to 900 MHz drives premium high DPI panels. The vPro eligible platform suits business detachables. The soldered package means flagship configs lock everything.

LPDDR3-1600 and DDR3L-1600 over two channels to 16 GB feed cores and graphics. The 5Y71 covers late 2014 flagships where top Core M turbo must fit 4.5 W.

Socket and motherboard compatibility

The 5Y71 solders to BGA 1234 at 30 × 16.5 mm with premium fanless cooling for 4.5 W. No swap exists. Flagship bodies pair it with fast SSDs and bright panels. Soldered memory locks size.

Business firmware adds vPro manageability on eligible designs. The LGA, PGA and BGA: CPU package types explained guide explains soldered premium limits.

Memory, PCIe and cooling

LPDDR3-1333 and 1600 and DDR3L-1600 over two channels to 16 GB with up to 25.6 GB/s suit flagship thin bodies. Dual channel pairs feed HD 5300 calls. Fast SSDs cover launches.

PCIe 2.0 with 12 lanes in x1, x2 and x4 splits serves SSDs and Wi-Fi. Thin designs use little wired expansion. Most builds stay integrated.

Cooling is premium passive spreading for 4.5 W with 6 W up tuning where bodies allow. Turbo to 2.9 GHz needs cool chassis. Skin limits trim sustained bursts.

Upgrade paths

On the same socket, the Intel Core M-5Y51 at 1.1 GHz to 2.6 GHz below saves cost, while Skylake-Y Core m7 parts cover newer flagships. All share BGA-1234.

A new premium detachable means a new device. The How to find your CPU socket type guide helps confirm soldered flagships.
