With that said, we're going to show those of you with a modern Intel processor how to monitor Windows 10 Power Throttling and turn it off/on for individual applications or the entire system. Those with older or Ryzen processors won't be able to make use of or disable this feature and should look elsewhere for power savings or performance gains. However, it's worth noting that Power Throttling is only available on Intel 6th gen and higher processors. The idea is that the application will still get its work done, but with a smaller footprint. To do so, it leverages modern CPU throttling features to ensure that the OS is spending the lowest amount of power possible on background tasks. Microsoft Power Throttling can net up to 11% more battery savings per charge with little negative impact. With the Windows 10 Fall Creators Update, Microsoft's OS has added feature called Power Throttling, a way to increase the battery life of laptops by slowing down background processes. 5 How to Turn Power Throttling On or Off for Specific Apps via Windows Settings My Surface Pro 7 i5 (i5-1035G4 CPU) sometimes gets stuck at 0.39 GHz.4 How to Disable Windows 10 Power Throttling with Registry Editor.3 How to Disable Windows 10 Power Throttling via Group Policy.2 How to Disable Power Throttling in Windows 10.1 How to Monitor Windows 10 Power Throttling with Task Manager.Microsoft's implementation of Kaby Lake-R may be slower than average when compared to "proper" Ultrabooks, but it's certainly the fastest Surface Pro series yet by far. ![]() Jumping from the 2017 Surface Pro i5 to the 2018 Surface Pro i5 brings a raw CPU performance boost of about 50 to 75 percent and the i7 SKUs see similar results. In other words, the 2018 series fares better, but only by smaller margins than we had hoped for.Įven after accounting for the steep throttling, however, the new Kaby Lake-R models are still significantly faster than the last generation Kaby Lake models. The latest Surface Pro i7 is an improvement with a performance drop of 12 percent vs. I opened Task Manager (which took 6+ seconds to load) to see. I was using my Surface Book fine until I noticed Microsoft Edge starting to lag out - opening new tabs would take 3 seconds and there was a visible delay when I typed into a text field, even though I had nothing open in the background. The largest drop in performance is last year's Surface Pro i5 SKU at 31 percent followed by this year's Surface Pro i5 at 25 percent. Surface Book CPU clock stuck low after a while. Aug0 According to numerous reports that we’ve seen, Microsoft Surface is suffering from a CPU throttling issue and the bug appears to be hitting various models, including the. Performance throttling can be observed across the board with some SKUs suffering more sharply. Our graph below plots the 2018 Surface Pro i5 and i7 SKUs against the 2017 Surface Pro i5 and i7 SKUs. Has the company stuck to its word?Ī good way of testing CPU performance sustainability is to run CineBench R15 Multi-Thread in a loop and recording the final scores for each round. Thus, users who purchased the Core i5 or i7 SKUs expecting Core i5 or i7 performance would actually be getting much slower results than advertised.įor the 2018 Surface Pro series, Microsoft has finally made the jump from 7th gen Kaby Lake to 8th gen Kaby Lake-R with the promise of improved cooling. Processor performance from the Core i5-7300U and Core i7-7660U SKUs would drop by as much as 18 to 31 percent over long periods. When we tested the Surface Pro 2017 series last year, we discovered a major drawback that most other reviewers either shrugged or ignored: Throttling.
