AMD’s 3D V-Cache technology is still relatively new, to date used on only a handful of AMD Ryzen processors. Today marks the launch of the fourth CPU to employ this innovative new technology, the Ryzen 7 7800X3D ($449). Designed as a stepped-down version of AMD’s current best processor for gaming, the AMD Ryzen 9 7950X3D, and with a lower price, the Ryzen 7 7800X3D might at first appear to be the gaming processor you’ve been waiting for. As it turns out, however, the Ryzen 7 7800X3D simply isn’t that practical a CPU pick except in edge cases. Most buyers should give it a pass unless the price eventually drops a bunch.Design: Cache for Days Like all of AMD’s Ryzen processors, the eight-core/16-thread, AM5-based Ryzen 7 7800X3D implements a chiplet design with multiple chips on a single package. Inside, you would see one chip known as a CCX that is produced on a 5nm manufacturing process, and this chip contains all eight of the Ryzen 7 7800X3D’s Zen 4 CPU cores. A second chip, known...
With ho-hum CPU performance for the money, AMD's gaming-minded Ryzen 7 7800X3D is a tough sell as a mainstream CPU, given that its strengths will benefit only a small sliver of gamers.
Large amount of cache; Energy efficient; PCI Express 5.0 support
Sluggish (relative) performance for the money in CPU-intensive tasks; Runs hot; Pricey for the performance level
