Core i3-1005G1 is a 64-bit dual-core low-end performance x86 mobile microprocessor introduced by Intel in mid-2019. This processor, which is based on the Ice Lake microarchitecture, is manufactured on Intel's 2nd generation enhanced 10nm+ process. The i3-1005G1 operates at 1.2 GHz with a TDP of 15 W and Turbo Boost frequency of up to 3.4 GHz. This chip supports up to 64 GiB of quad-channel LPDDR4X-3733 memory and incorporates Intel's UHD Graphics with a clock of 300 MHz and a burst frequency of 900 MHz.

This model supports a configurable TDP of TDP-up of 25 W.

[Edit/Modify Cache Info]

Cache Organization
Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory.

The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC.

Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies.

Note: All units are in kibibytes and mebibytes.
