What the Core i7-5557U is

The Core i7-5557U leads dual core Broadwell-U on BGA 1168 for thin workstations. Intel set two cores and four threads at 3.1 GHz base with turbo to 3.4 GHz. Four megabytes of cache and 28 W sustain creation bursts. Iris Graphics 6100 up to 1100 MHz is the top thin graphics of the family.

High base clocks for a dual core keep timelines responsive without discrete heat. Turbo to 3.4 GHz leads single thread bursts among U parts. The soldered SoC pairs with fast memory for Iris bandwidth. Buyers pick the 5557U where thin design must still cut photos and 1080p video.

DDR3L and LPDDR3 over two channels to 16 GB feed the system. Sixteen gigabytes suits workstation-lite use. The premium covers chassis, display and Iris tuning as much as clocks.

Socket and motherboard compatibility

The 5557U solders to BGA 1168 with flagship 28 W thin cooling. No swap exists. Workstation-lite bodies solder RAM for speed, so configure once. Docks and color accurate panels complete the setup.

Iris board design centers on display outputs and SSD speed. The LGA, PGA and BGA: CPU package types explained guide covers fixed CPU limits. Verify ISV expectations, since dual cores cap heavy renders despite Iris.

Memory, PCIe and cooling

Memory to 16 GB over two channels with fast options suits thin creation. Dual channel is mandatory for Iris peaks. Sixteen gigabytes covers catalogs with background apps.

PCIe 2.0 with 12 lanes feeds SSDs and radios. Large SATA SSDs hold projects. Gen2 interface makes capacity and reliability more useful than NVMe speed.

Cooling is premium thin pipes for 28 W. Sustained 3.1 GHz needs desk airflow. Lap sessions trim turbo quickly.

Upgrade paths

No soldered upgrade exists. Step down to the Intel Core i5-5287U at 2.9 GHz to 3.3 GHz for i5 value, or to the Intel Core i7-5500U at 15 W for battery life. All share BGA-1168.

A new thin workstation is the only move up. The How to find your CPU socket type guide helps identify soldered Iris flagships.
