We discovered similar results on the last generation Surface Pro 6 and even Surface Pro 5 and the latest Surface Pro 7 appears to be no different. While this looks good on paper, the steeper throttling can be off-putting to performance users. After accounting for the throttling on both devices, users can expect a 22 percent deficit in processor performance on the tablet relative to the Surface Laptop 3.ĬPU throttling is not uncommon on tablets, but it's particularly noticeable on the Surface Pro series since Microsoft insists on equipping its flagship models with the same Intel U series processors as found on larger Ultrabooks. The tablet eventually stabilizes at a nearly 30 percent performance dip from its original score. 780 points) only to degrade faster and steeper over time on the Surface Pro 7 tablet. 32 Posted by 7 years ago A big way to mitigate throttling on the SP4 i7: setting max processor state to 99 (detailed explanation inside) I'm gonna assume you've already disabled connected standby in order to be able to use Intel XTU and edit your power plans. Performance starts out relatively the same between the two systems at the beginning of the run (770 points vs. The Intel processors of both flagship devices throttle. We can observe CPU performance changes over time on each system when running CineBench R15 Multi-Thread in a loop as shown in the chart below. My Surface Pro 7 i5 (i5-1035G4 CPU) sometimes gets stuck at 0.39 GHz. Septem0 Firmware update for Surface Pro 6 and Surface Book 2 throttled the processing power of the flagship hardware. Keeping the slider in the Best performance setting will naturally be more taxing for the CPU and lead to Surface Book 2 CPU throttle issues. Adjust power mode to a less CPU intensive setting. Our latest example is between the 15-inch Surface Laptop 3 15 and 12.3-inch Surface Pro 7 tablet each equipped with an Intel 10th gen Core i7-1065G7 CPU. When the process is complete, restart your PC and see if the problem is fixed. It's easy to forget that larger laptops are generally faster than thinner laptops despite having similar internal specifications. Our users are reporting cases where the devices are very slow. 4Ghz (Prochot) We have a fleet of about 200 Surface Pro 6 devices. We've reached out to Microsoft for comment and will update this post when we learn more.As we've mentioned before in the past, the performance of a processor can vary greatly between two different laptops even if both are equipped with the same CPU. ago by UnluckyJelly Surface Pro 6, Throttling issue CPU stuck at. GPU, display, battery, driver and electrical issues have plagued a variety Surface products, with Consumer Reports pulling their recommendation for over a year. While the Surface Pro 6 remains one of the best Windows 2-in-1 devices, Microsoft's Surface line has a length history of problems. Microsoft has issued a statement to TechRepublic promising a speedy fix via a firmware update. Some users have reported that removing the devices from their docks or AC adapters solves the problem, while others state that even rebooting does not set the clock speed back to normal. It looks like the culprit is BD PROCHOT, an internal alert used by peripherals to tell a system's CPU to throttle its clock speed down to avoid overtaxing the processor. The specs of the Surface devices are typically snappy, so with the Surface Pro 6 running at 1.9GHz, for example, the drop to 400MHz is an immense performance hit. The problem seems to stem from a firmware update that was released on August 1st, according to TechRepublic. A Windows feature meant to keep a device from overheating is causing Microsoft's Surface Pro 6 and Surface Book 2 to run at a cripplingly slow speed.
