Intel Core i3-1005G1 is a power-efficient dual-core processor with Intel’s “Sunny Cove” microarchitecture launched in the third quarter of 2019. It has two cores capable of hyper-threading processing up to four threads at any given time. The cores are clocked at a base frequency of 1.2GHz and a maximum clock speed of 3.4GHz with access to only 4MB cache memory. The Core i3-1005G1 has some noticeable improvements over its predecessors: it is fabricated using Intel’s 10nm process node which enables lower power consumption than the previous generation of CPUs that are based on 14nm processing technology.
It’s TDP is set at 15W which can be configured as low as 13W at a cTDP-down frequency of 900MHz. The Core i3-1005G1 also features Intel’s 10th Gen UHD Graphics integrated into the SoC package itself, which supports DirectX 12/OpenGL 4.5. Additionally, the i3-1005G1 also supports Coffee Lake Display (CLD) via Intel’s Quick Sync Video (QSV) media engine. The UHD Graphics packs 32 execution units which operates at a base frequency of 300MHz and a maximum speed of 900MHz. With this graphics specifications, this processor is perfect for routine productivity applications, light gaming, or streaming videos.
This CPU provides support for faster system memory types which translates to negligible CPU performance. It features a dual-channel DDR4 memory controller with support for up to 64GB at speeds of up to 3200MHz, which can be upgraded to higher frequencies using Intel’s Turbo Boost technology. Besides, it supports LPDDR4 memory controller that runs up to 3733MHz RAM thus saving on power consumption for laptops.
One of the key advantages Core i3-1005G1 has over Core i3-10110U, when compared performance-wise, is its more modern manufacturing process node (10nm vs. 14nm) despite the 21% higher turbo boost frequency Core i3-10110U has. Also, the Core i3-1005G1 has a higher single-core performance in Geekbench v5 single-core CPU tests. Based on CPU specifications, Core i3-1005G1 is a slight update over the 8th gen Core i3 CPUs with the main difference being its support for faster memory types. Therefore, this chip should offer similar performance compared to higher clocked 8th gen chips, for example, Core i3-8145U.
