If you are one of the few that have been waiting for the Ryzen 9 3900X to get back in stock, then we have good news for you. The Ryzen 9 3900X has popped up at Amazon and Best Buy for $499.99.

Despite the recent price hikes, AMD has assured us that the Ryzen 9 3900X's MSRP remains unchanged. As retailers around the country start to replenish their Ryzen 9 3900X stock, the pricing should fall back down to $499.99 soon.

The Ryzen 9 3900X is AMD's current flagship Zen 2 chip, but will ultimately take the back seat once the Ryzen 9 3950X arrives next month. The Ryzen 9 3900X is no slouch, either. The 7nm processor is equipped with 12 cores, 24 threads, and up to 64MB of L3 cache, which will surely appease any hardcore enthusiast. The chip ticks at a 3.8 GHz base clock and 4.6 GHz boost clock.

The Ryzen 9 3900X has an unlocked multiplier, so manual overclocking is on the table as well. The 12-core processor also sports 24 high-speed PCIe 4.0 lanes to exploit the latest PCIe 4.0 SSDs and graphics cards. The Ryzen 9 3900X's other features include support for dual-channel DDR4-3200 memory and a 105W TDP (thermal design power). AMD bundles the Ryzen 9 3900X with the brand's Wraith Prism CPU cooler in case you don't want to spend extra on an aftermarket solution.

    I don't have ad blocker because I understand some services use ad sense to pay their daily costs, but I literally can't even read this article because of the ads. Page keeps disappearing and all I see are ads for gears 5, verizon, and a mini-player video on the side from tom's hardware that I don't even care about nor asked for.

    10/10 web-design guys.

    I noticed the 3900X showed up at Micro Center recently too, although at a price elevated above MSRP. I'll pick one up once the price comes back down to MSRP and the Borderlands 3 promotion ends. Hopefully AMD doesn't follow the Borderlands 3 promo with another Gearbox, 2K, or Take Two promotion...ugh!

    Seems like a problem for the US mostly.
    In Sweden the 3900X has been in stock all the time an the price has been stable since launch.
