What the Core i5-1145G7 is
The Core i5-1145G7 is a 4-core mobile processor that Intel launched in September 2020 for thin business laptops in the UP3 range. Its Willow Cove cores run a 2.6 GHz base at 28 W to 4.4 GHz turbo with Hyper-Threading for 8 threads. Cache is 8 MB of Intel Smart Cache.
The chip gives business buyers a vPro i5 with the highest UP3 i5 base clock. The 10 nm SuperFin process holds 2.6 GHz sustained where 15 W parts sit near 1.4 GHz. Configurable power from 12 W to 28 W lets makers tune the same die, but the 28 W setting shows its full pace.
Intel Iris Xe Graphics handle display output, with 80 execution units at up to 1.30 GHz. The multiplier is locked. The package is FCBGA1449 soldered at 45.5 × 25 mm.
Socket and motherboard compatibility
The 1145G7 fits BGA 1449 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 UP3 platform with DDR4 or LPDDR4x memory.
Because the package is soldered, buyers compare complete business laptops rather than separate parts. A buyer who needs a lower power thin design steps to the Intel Core i5-1135G7 at 15 W. A buyer who needs embedded ECC takes the Intel Core i5-1145GRE twin with matching graphics.
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 DDR4 up to 3200 MT/s or LPDDR4x up to 4267 MT/s across two channels to 64 GB. Business designs often use dual channel memory for Iris Xe graphics speed. There is no DDR5 path on Tiger Lake-U.
The processor exposes PCIe Gen4 from the CPU plus Thunderbolt 4 through the board for storage and docks. Business laptops lean on Thunderbolt for desk setups where internal lanes stay few. Cooler mounting uses no desktop pattern. Cooling follows the laptop thermal design with dual heat pipes sized for 28 W.
vPro manageability joins the CPU for fleet use. Remote management and stable firmware matter more than headline turbo in this segment, so vendors lock validated BIOS versions for years. Four cores with eight threads cover office multitasking with headroom.
Upgrade paths
On the same BGA1449 footprint there is no CPU upgrade path, since the chip is soldered. Owners who need faster graphics move to an i7 UP3 part such as the Intel Core i7-1195G7 rather than a chip swap. Memory is often soldered, which closes that path as well.
Within i5 UP3, the step down is the Intel Core i5-1135G7 for 15 W thin designs. Both share 4 cores, 8 threads and Iris Xe graphics, so the choice is sustained clocks and power rather than platform.
Moving past UP3 entirely means a new laptop on a later platform. For buyers choosing in 2020, the 1145G7 suited 28 W business designs with vPro, while 15 W parts asked thinner bodies. The two share Willow Cove and 10 nm SuperFin on the same package family.
Frequently asked questions
What socket does the Intel Core i5-1145G7 use?
It uses BGA 1449, a soldered grid array with 1449 balls. The chip cannot be removed or replaced.
What memory does the Core i5-1145G7 support?
DDR4 up to 3200 MT/s or LPDDR4x up to 4267 MT/s in two channels to 64 GB. Dual channel memory matters for Iris Xe graphics speed.
Can the Core i5-1145G7 be overclocked?
No. The multiplier is locked, and laptop firmware does not expose desktop overclocking controls. The 28 W setting holds 2.6 GHz base with dual heat pipes.
How does the 1145G7 differ from the 1135G7?
The 1145G7 is a 28 W vPro part with 2.6 GHz base, while the Intel Core i5-1135G7 is a 15 W part with 1.4 GHz base. Both share 4 cores, 8 threads and Iris Xe graphics.
