Intel Core i3-1005G1

Intel 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).

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).

Performance

The average 1005G1 in our database is a disappointment, its multi-thread benchmark scores only matching those of Intel Core i5-7267U and AMD Ryzen 3 2300U. This is unfortunately in line with what we've been seeing from most other Ice Lake family processors. While not as slow as an Intel Celeron, a Core i3-1005G1 will still look out of place in anything but entry-level laptops and mini-PCs.

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.

Power consumption

The Core i3 has a 15 W default TDP (also known as the long-term power limit), a value that laptop manufacturers are allowed to reduce slightly - 13 W beingthe lower limit - resulting in lower clock speeds and lower performance. The CPU is built with Intel's first-gen 10 nm process for OK energy efficiency.
