Intel 11th generation Core i5 Rocket Lake processors have 6 physical cores plus Hyper Threading technology, allowing them to work on up to 12 threads simultaneously.
These Socket 1200 CPUs are ideally paired with a 500-series motherboard, although some older 400-series motherboards are not compatible after a BIOS update. However, you will not get the full benefit of the CPU, such as PCIe 4.0 using a 400-series motherboard.
