u/Akira13645 on Reddit has observed that Intel has updated the Core i3-x100F series for the final quarter of 2020 (4Q2020). This recently-established line exists to offer budget processing without UHD graphics. The new i3-10100F still fits this mold, although it also has marked Comet Lake-afforded advantages over its predecessor.
For example, it is the first F-variant to exhibit Intel Hyper-Threading Technology – which means double the threads for its 4 cores for the first time. They can use Turbo Boost Max v2.0 for a maximal clock of 4.3GHz, whereas the i3-9100F could only go up to 4.2GHz.
The i3-10100F also now supports up to 128GB of DDR4-2666 RAM, whereas its predecessor was rated for half that much DDR4-2400 memory. There is also a maximum bandwidth of 41.6 GB/s compared to 37.5 GB/s. The Comet Lake-based i3 F variant also uses the LGA 1200 socket rather than the LGA 1151.
Then again, the two chipsets share a TDP of 65W, a 6MB cache, have 2-channel memory and are, of course, still both 14nm. The Core i3-10100F is also still pitched at low-powered PCs, probably thin clients and tablets, and has an MRSP of US$79 to $97.
