AMD Introduces Precision Boost Overdrive 2, Boosts Single Thread Performance

If you’ve already bought, or plan on buying, a Ryzen 5000 processor, AMD just made the deal a whole lot sweeter. AMD’s Precision Boost Overdrive (PBO) introduced one-click hassle-free overclocking to the masses for the Ryzen lineup of processors. Still, while the tech boosts performance in multi-threaded workloads, it has long failed to benefit single-threaded workloads. That changes in December when AMD’s new Precision Boost Overdrive 2 (PBO2) lands in BIOS patches. The new PBO2 boosts single-threaded performance while retaining the benefits of the existing multi-core boosts, and even adds a little extra oomph there, too. 

The new PBO2 only works with Ryzen 5000 series processors, and AMD is also bringing in a new sophisticated undervolting technique to Ryzen 5000 processors for the undervolters among us.

We have plenty of testing that shows the benefits of PBO in our recent Ryzen 9 5950X and 5900X reviews, not to mention the Ryzen 5 5600X review. Still, AMD’s impressive demo benchmarks show PBO2 basically enabling users to step up a tier over their existing processor in single-threaded performance. That’s impressive given that AMD’s Zen 3 processors have already soared to the top of the single-threaded performance CPU Benchmarks Hierarchy.

For example, PBO2 grants the Ryzen 7 5800X nearly the same exceptional single-threaded performance of the beastly Ryzen 9 5900X. As with all overclocking, and AMD’s policy with the first-gen PBO, the new PBO2 invalidates your warranty. But given the relatively risk-free performance gains we’ve seen with PBO, and the fact that the automatic nature of the feature avoids using excessively dangerous amounts of voltage, we think PBO2 overclocking will continue to be the safest path to wringing out the best performance possible. That said, proceed at your own peril.
