The slower, non-X versions of AMD’s Zen 3-based Ryzen 9 5900X and Ryzen 7 5800X processors are now available as part of select prebuilt systems. These include Dell and Alienware’s new Aurora Ryzen Edition R10 Gaming Desktop, a high-performance PC that can be configured with Ryzen 9 5900 and Ryzen 7 5800 CPUs. The key differences with these OEM-only chips lie in their clock speeds and TDPs—the Ryzen 9 5900, for instance, features a base clock and max boost clock that’s 0.7 GHz and 0.1 GHz slower than the X version, respectively. These processors also have a TDP difference of 40 watts.
The Ryzen 7 5800 is at least $150 US cheaper than the Ryzen 7 5800X configuration while the Ryzen 9 5900 is a whole $300 US cheaper than the Ryzen 9 5900X configuration. This is pretty good value for desktop CPUs that will offer almost 95% of the performance at far better efficiency. It also looks like the Ryzen 5000 OEM parts from AMD feature a much better bin. A user who got his Ryzen 7 5800 OEM from Alienware confirmed on Reddit that his chip turned out to be a golden sample when tested within the Clock Tuner For Ryzen (CTR) utility.
