Intel Core i3-8130U socket: BGA 1356

What the Core i3-8130U is

The Core i3-8130U is a two core, four thread mobile processor with a 2.2 GHz base and up to 3.4 GHz turbo. It carries 4 MB of Smart Cache and a 15 W TDP on the 14 nm process. Intel ARK lists configurable TDP down to 10 W at 800 MHz for quiet bodies. The database entry still shows an older 2.4 GHz base from pre launch leaks, which Intel corrected to 2.2 GHz at launch.

It is the late dual core of the Kaby Lake-R family, where the i5 and i7 parts moved to four cores. Two cores with Hyper-Threading cover office work and study loads in 2018 thin laptops. The multiplier is locked.

UHD Graphics 620 runs from 300 MHz base to 1.0 GHz max for laptop displays without a separate chip. Memory runs as DDR4-2400 or LPDDR3-2133 in two channels up to 32 GB. The chip is soldered in the FCBGA1356 package at 42 by 24 mm.

Socket and motherboard compatibility

The 8130U is soldered to the board in the BGA 1356 package and cannot be replaced. Upgrading means replacing the board or the whole laptop, so buyers should choose memory size at order time. The LGA, PGA and BGA: CPU package types explained guide explains soldered package trade offs.

Intel ARK lists Sockets Supported as FCBGA1356 with a 42 by 24 mm package. Boards pair it with single fan cooling tuned for 15 W bursts, dropping to 10 W where makers favor silence. Check the laptop maker specs for the configured TDP.

There is no socket retention or aftermarket mounting choice. Do not confuse this BGA package with LGA 1356, the 2012 server socket of the same number. The Intel Core i7-8565U is a later 15 W Whiskey Lake-U alternative on BGA 1528 with higher turbo.

Memory, PCIe and cooling

Memory support covers DDR4-2400 modules or soldered LPDDR3-2133 in two channels up to 32 GB, with up to 37.5 GB per sec of bandwidth. ECC is not supported. Two channel operation helps the integrated graphics, since it shares system memory.

PCI Express arrives as version 3.0 with 12 lanes from the CPU for NVMe storage and board devices. Laptop designs typically wire a single NVMe SSD plus wireless. There is no cooler to swap, so thermal design stays with the maker.

Upgrade paths

There is no CPU upgrade path on BGA 1356. The only moves are a larger SSD where the slot allows it or a whole laptop replacement. Buyers who need four cores should choose Kaby Lake-R i5 parts on the same package at order time.

Staying on this board, matched memory channels and a clean OS install help more than chasing clocks. The locked multiplier removes overclocking as a tuning option.
