What the Core M-5Y51 is
The Core M-5Y51 serves premium Broadwell-Y 2 in 1 devices on BGA 1234 with strong turbo. It runs 2 cores and 4 threads at 1.1 GHz base with turbo to 2.6 GHz. Four megabytes of Smart Cache cover office multitasking. Power is 4.5 W on 14 nm from October 2014 with 6 W configurable up tuning at 1.3 GHz.
Higher base than 5Y31 class parts keeps everyday work snappy without waiting for turbo. HD Graphics 5300 from 300 MHz to 900 MHz drives high DPI panels. The 4.5 W envelope with SDP points suits sealed premium bodies. The soldered package means configuration locks at order time.
LPDDR3 and DDR3L over two channels to 16 GB feed cores and graphics. The 5Y51 covers premium detachables where base speed and turbo must both lead at 4.5 W.
Socket and motherboard compatibility
The 5Y51 solders to BGA 1234 with premium fanless cooling for 4.5 W. No swap exists. Flagship thin bodies pair it with fast SSDs and bright panels. Soldered memory locks size.
SoC radios and storage serve peripherals. The LGA, PGA and BGA: CPU package types explained guide explains soldered premium limits.
Memory, PCIe and cooling
LPDDR3-1600 and DDR3L-1600 over two channels to 16 GB suit flagship thin bodies. Dual channel feeds HD 5300 calls. Fast SSDs cover launches.
PCIe 2.0 with 12 lanes serves SSDs and Wi-Fi. Thin designs use little wired expansion. Most builds stay integrated.
Cooling is passive spreading for 4.5 W with 6 W up tuning where bodies allow. Turbo holds better on metal unibodies.
Upgrade paths
On the same socket, the Intel Core M-5Y31 at lower clocks below saves cost, while the Intel Core M-5Y71 at 1.2 GHz to 2.9 GHz above tops the line. All share BGA-1234.
Skylake-Y Core m parts cover newer premium duty. The 5Y51 holds upper mid Core M value.
