AMD’s Ryzen 9 3900X has dropped to an all-time low price of approximately $400 across different online retailers. While Amazon is selling the 12-core CPU for $415, the chip is even cheaper at Microcenter with a price-tag of $399. Intel’s newly launched 10th Gen Comet Lake-S processors, on the other hand, are either out of stock or overpriced everywhere you look. The notably slower Core i7-10700K is selling for $699 on Amazon and is unavailable on Newegg. Microcenter, as usual, has the best deal with an MSRP of $469 for the 10700K, but even that’s considerably higher than the 3900X, despite offering fewer threads and marginally higher single-threaded performance.
The Ryzen 9 3900X is part of AMD’s 3rd Gen Matisse family. It comes with 12 cores and 24 threads and a base clock of 3.8GHz. The CPU has a single-core boost of 4.6GHz but unless you have an AIO cooler, you’ll mostly be limited to 4.2 to 4.3GHz. The 3900X is essentially an HEDT processor, offering performance in the same range as Intel’s Cascade Lake-X chips at half the price. With a good liquid cooler and mild overclocking, it catches up to most Intel 10th Gen chips too.
