What the Core M-5Y70 is
The Core M-5Y70 is a launch flagship Broadwell-Y part on BGA 1234 for first premium 2 in 1 devices. 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 work. Power is 4.5 W on 14 nm from September 2014 with the Yoga 3 Pro as the showcase device.
Launch timing put it in the first fanless Core notebooks ever sold. HD Graphics 5300 from 100 MHz to 850 MHz drives early high DPI panels. Battery life leads over bursts in these first bodies. The soldered package means early adopter configs lock everything.
LPDDR3 and DDR3L over two channels to 16 GB feed cores and graphics. The 5Y70 covers launch window flagships where first fanless Core branding matters.
Socket and motherboard compatibility
The 5Y70 solders to BGA 1234 with first generation fanless cooling for 4.5 W. No swap exists. Launch devices pair it with SSDs. Soldered memory locks size.
Early Broadwell-Y firmware tuned turbo conservatively. 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 launch thin bodies. Dual channel feeds HD 5300. Modest populations cover launch apps.
PCIe 2.0 with 12 lanes serves SSDs and radios. Thin SSDs match the power budget. Most builds stay integrated.
Cooling is first generation passive spreading for 4.5 W. Early bodies throttle sooner than later designs. Firmware updates helped sustained behavior.
Upgrade paths
On the same socket, the Intel Core M-5Y10 at lower clocks below saves battery, while the Intel Core M-5Y71 at 1.2 GHz to 2.9 GHz above tops turbo. All share BGA-1234.
Skylake-Y covers newer thin flagships. The 5Y70 holds launch flagship Core M value.
