AMD Ryzen 9 7900X3D 12-core Processor Drops to $389
AMD's 12-core/24-thread Ryzen 9 7900X3D processor that comes with 3D Vertical Cache technology, is seeing a slew of price-cuts. The SKU appears to be trapped between the 8-core 7800X3D, which remains the fastest desktop processor for gaming; and the 16-core 7950X3D, which is AMD's flagship. A Newegg listing at $408 with a $20 discount coupon see its effective retail price drop to as low as $389, which is just $20 more than the 7800X3D.
Would you pay $20 for four more cores? The choice is not so simple. While the 7900X3D is a 12-core processor, it features a dual-CCD design, with a 6+6 core arrangement between the two CCDs. Just like with the 7950X3D, only one of the two CCDs has the 64 MB 3D Vertical Cache, or 96 MB of L3 cache; while the other is a regular "Zen 4" CCD with 32 MB of on-die L3 cache. AMD's chipset drives use UEFI CPPC preferred-core flagging to guide gaming workloads to the CCD with the 3D V-cache. While we haven't had a chance to test the 7900X3D, this chip is tested by Tom's Hardware to still be faster than the Core i9-13900K at gaming.
