What the Core i3-1110G4 is
The Core i3-1110G4 is a 2-core mobile processor that Intel launched in the first quarter of 2021 for thin laptops in the UP4 range. Its Willow Cove cores run a 1.8 GHz base at 15 W to 3.9 GHz turbo with Hyper-Threading for 4 threads. Cache is 6 MB of Intel Smart Cache.
The chip gives small thin buyers a dual core UP4 option with lower board area than UP3. The 10 nm SuperFin process pushes one core to 3.9 GHz for responsive launches. Configurable power from 7 W to 15 W lets makers tune the same die for fanless moments or active cooling.
Intel UHD Graphics for 11th Gen processors handle display output, with 48 execution units. The multiplier is locked. The package is FCBGA1598 soldered at 26.5 × 18.5 mm.
Socket and motherboard compatibility
The 1110G4 fits BGA 1598 only. The chip solders to the laptop board, so there is no socket retention and no later processor upgrade. Board support is fixed to the UP4 platform with LPDDR4x memory soldered nearby.
Because the package is soldered, buyers compare complete small laptops rather than separate parts. A buyer who needs four cores in a similar envelope steps to the Intel Core i3-1120G4 with double the threads. The dual core 1110G4 stays in its value thin role for its whole service life.
The How to find your CPU socket type guide explains how to confirm a soldered package from the system specifications. For service, a failed processor means a board replacement through the laptop maker.
Memory, PCIe and cooling
The memory controller supports LPDDR4x up to 4267 MT/s across two channels to 32 GB. UP4 designs solder the memory for low idle power, so capacity is fixed at purchase. There is no DDR4 SO-DIMM path on UP4 boards.
The processor exposes PCIe Gen4 from the CPU plus Thunderbolt 4 through the board for storage and docks. Small designs lean on Thunderbolt where internal lanes stay few. Cooler mounting uses no desktop pattern. Cooling follows the laptop thermal design with a slim fan sized for 15 W.
Two cores with four threads cover study and office work in small bodies. Single thread bursts to 3.9 GHz keep launches snappy, while all-core holds follow the configured TDP between 7 W and 15 W. Makers publish the configured value per model.
Upgrade paths
On the same BGA1598 footprint there is no CPU upgrade path, since the chip is soldered. Owners who need four cores move to the Intel Core i3-1120G4 rather than a chip swap. Memory is also soldered, which closes that path as well.
Within UP4 i3, the step up is the 1120G4 for 4 cores with 8 MB cache. Both share UHD graphics and 10 nm SuperFin, so the choice is core count rather than platform.
Moving past UP4 entirely means a new laptop on UP3 with DDR4 options or a later platform. For buyers choosing in 2021, the 1110G4 suited small value thin designs at 15 W, while UP3 dual cores asked larger bodies. The two share Willow Cove, but they do not share boards.
Frequently asked questions
What socket does the Intel Core i3-1110G4 use?
It uses BGA 1598, a soldered grid array with 1598 balls. The chip cannot be removed or replaced.
What memory does the Core i3-1110G4 support?
LPDDR4x up to 4267 MT/s in two channels to 32 GB. UP4 boards solder the memory, so capacity is fixed at purchase.
Can the Core i3-1110G4 be overclocked?
No. The multiplier is locked, and laptop firmware does not expose desktop overclocking controls. Sustained speed follows the maker configured value between 7 W and 15 W.
How does the 1110G4 differ from the 1120G4?
The 1110G4 has 2 cores on BGA1598, while the Intel Core i3-1120G4 has 4 cores on the same package. Both share UHD graphics and 10 nm SuperFin.
