Intel Core i3-1005G1

The Intel Core i3-1005G1 is a power efficient dual-core SoC for laptops and Ultrabooks based on the Ice Lake-U generation that was announced in Mai 2019 (Computex). It integrates two Sunnycove processor cores (4 threads thanks to HyperThreading) clocked at 1.2 (base) - 3.4 GHz (single and dual core Turbo). According to Intel the Sunnycove cores achieve 18% more IPCs (Instructions per Clock) and therefore the CPU performance should be similar to the higher clocked Whiskey-Lake predecessors (e.g. Core i3-8145U with 2.3 - 3.9 GHz) or an older Core i7-7660U (2.5 - 4 GHz Dual Core).

The biggest improvement for Ice-Lake is the integrated Gen 11 graphics processor called UHD Graphics G1. The Core i3-1005G1 integrates the smallest GPU, the UHD Graphics with 32 of the 64 EUs clocked at 300 - 900 MHz. The higher-end Iris Plus G4 and G7 offer higher clock speeds (up to 1100 MHz) and up to 64 EUs.

Other improvements for Ice Lake are the AI hardware acceleration and the partial integration of Thunderbolt and Wifi 6 in the chip. The integrated DDR4 memory controller supports modules with up to 3200 MHz (and LPDDDR4 3733).

The Core i3-1005G1 is produced on the first-gen 10 nm Intel process that should offer a comparable performance to the 7 nm TSMC process. The TDP is specified at 15 Watts and therefore the CPU can be used in thin and light laptops (but usually with a fan). Intel offers a configurable TDP of 13 - 25 Watts for the partners resulting in some serious performance differences. The CPU will run at just 900 MHz if limited to 13 Watts.
