Intel Core i3-10100 vs Intel Core i5-4570T

The i3-10100 was a solid budget chip in 2020 thanks to the return of Hyper-Threading, but it is now outdated, held back by PCIe 3.0, DDR4-2666 limits, and an aging 14nm process.

Best for: The i3-10100 only makes sense today if you are upgrading an existing LGA 1200 system on an extremely tight budget and can find the chip used for a very low price. It can also be considered if you are repairing an office PC that already uses an LGA 1200 motherboard and you just need a drop-in replacement. However, for any new build, it is obsolete. The i3-12100 offers a massive architectural leap for a similar price, featuring PCIe 5.0, DDR5 support, and dramatically higher single-core performance. Avoid building a new system around the 10100 entirely.

An efficient and cool-running chip for its time, but severely outdated by modern dual-core standards.

Best for: If you are considering the Core i5-4570T today, it should only be for upgrading an existing LGA 1150 system where your current chip is failing, or for building a very basic retro or office PC using salvaged parts. It holds no value for new purchases due to its age and lack of modern feature support. If found cheaply, it can serve as a capable home server or HTPC processor, handling media streaming and basic network tasks adequately. However, its dual-core limitation will be a bottleneck for modern web browsing with heavy scripts. Do not spend more than a few dollars on this processor. Anyone building a new system should look toward modern 12th or 13th Gen Intel alternatives, or AMD's Ryzen series, which offer vastly superior efficiency and performance.
