Is the performance of AMD Ryzen mobile on battery really that bad?
If you’re even asking that question, you’ve no doubt heard Intel’s claims that Ryzen 4000 CPU performance tanked when running on battery. Plugged-in performance was dandy, but in tests of multiple Ryzen 4000U-based laptops, performance dropped huge amounts on battery, depending on the task.
While some reviewers checked AC and DC performance and found some nuggets of truth to Intel’s claims, the issue has mostly lain dormant for the last six months. Now that Ryzen 5000 is out, we decided to circle back and see if the claims still held. As you’ll see in our tests, what’s “good” or “bad” depends on whether you care more about performance or battery life.
