Intel · Core i3 · 2019 · LGA1151
The Intel Core i3-9100 is a desktop processor with 4 cores, released in 2019 at an MSRP of $122. It is part of the Core i3 lineup, using the 9th Gen platform, and fits the LGA1151 socket. Internally, it is built on the "Coffee Lake Refresh" architecture. Thanks to Intel Hyper-Threading, each core can handle two instruction streams simultaneously, yielding a total of 8 threads for improved parallelism. The Core i3-9100 has a base clock of 3.6 GHz and can boost up to 4.2 GHz depending on workload and thermal headroom. Intel manufactures the "Coffee Lake Refresh" silicon on a 14nm process node. Its multiplier is locked, so any overclocking has to come from raising the base clock rather than the multiplier. This processor supports DDR4 memory. With a TDP of 65W, the Core i3-9100 is an efficient chip suitable for modest cooling solutions. Integrated graphics are provided by the UHD 630 solution, so a discrete GPU is not required for display output. The cache hierarchy consists of 32KB/core of L1, 1MB of L2, and 6MB of L3 cache.
4-core with Hyper-Threading (4C/8T). Intel restored HT to the i3 tier in 9th Gen while removing it from the i7.
