What the Core i3-5157U is
The Core i3-5157U brings Iris graphics to i3 Broadwell-U on BGA 1168 for thin creation laptops. Intel set two cores and four threads at a fixed 2.5 GHz with 3 MB of cache. Power is 28 W on 14 nm from January 2015. No turbo keeps behavior steady while graphics carry the premium.
Iris Graphics 6100 up to 1000 MHz separates it from HD i3 parts in photo edits and 4K video. Fixed 2.5 GHz is high for a 28 W dual core, so office bursts feel quick. Four threads cover conferencing with background tools. The soldered SoC means chassis cooling decides how long graphics hold peak.
DDR3L and LPDDR3 over two channels to 16 GB feed cores and Iris graphics. Paired memory matters more here than on HD parts. Buyers pick the 5157U where Iris must fit an i3 budget without i5 turbo pricing.
Socket and motherboard compatibility
The 5157U solders to BGA 1168 with larger 28 W cooling than 15 W ultrabooks. No later swap exists. Thin Iris bodies often solder LPDDR3 for bandwidth. Check memory size at purchase, since upgrades rarely exist.
PCH-LP SoC design keeps boards compact. The LGA, PGA and BGA: CPU package types explained guide explains soldered limits. Verify display outputs for 4K, since Iris earns its keep on high resolution panels.
Memory, PCIe and cooling
DDR3L-1600 and LPDDR3 to 16 GB over two channels suit Iris thin clients. Dual channel is required for full graphics speed. Eight to sixteen gigabytes covers edits with browsers open.
PCIe 2.0 with 12 lanes feeds SSDs and radios. SATA SSDs match Gen2 lanes. A larger SATA SSD helps photo libraries more than clock hunting.
Cooling is a bigger fan and pipes for 28 W. Iris loads heat the body faster than HD loads. Vent clearance protects sustained 2.5 GHz.
Upgrade paths
No CPU path exists soldered. Step to the Intel Core i5-5257U adding turbo to 3.1 GHz with the same Iris class, or down to the Intel Core i3-5020U at 2.2 GHz and 15 W with HD graphics. All share BGA-1168.
A new thin laptop is the only platform move. The How to find your CPU socket type guide confirms soldered Iris designs.
