Verdict

The Intel Core i3-10305 is a 10th Gen 'Comet Lake' desktop processor featuring 4 cores and 8 threads with a base clock of 3.8 GHz and a max turbo boost of 4.5 GHz. Built on a 14nm process with a 65W TDP, it includes 8MB of Intel Smart Cache, support for up to 128GB of dual-channel DDR4-2666 memory, and integrated Intel UHD Graphics 630. Main pros include its improved multitasking over previous i3 generations due to Hyper-Threading and its decent single-core performance for everyday office tasks and light gaming; however, cons include its locked multiplier which prevents overclocking, reliance on the older PCIe 3.0 standard, and the lack of support for faster DDR5 or high-speed DDR4 memory natively.
