Intel Core i9-12900K vs AMD Ryzen 7 5700X
If you're torn between the Intel Core i9-12900K and the AMD Ryzen 7 5700X, the i9-12900K takes the lead with its powerhouse performance. With 16 cores and a max boost clock of 5.2 GHz, it outshines the 8-core Ryzen 7 5700X in multi-threaded tasks, making it ideal for serious creators and gamers alike. The Ryzen 7 5700X is no slouch and offers impressive efficiency with a 65W TDP. In my testing, the 5700X runs cooler than its rivals, meaning you won’t need high-end cooling solutions, which can save you money in the long run. This makes it a smart choice for budget-conscious gamers or anyone looking to upgrade an older AM4 build without breaking the bank in 2026.
