Reposing this: I would warn against people trying any trick to stop the throttling unless it is absolutely necessary. Personally, I'm rapidly coming to the conclusion that the SP3 is not for me, and I'll wait to see what Broadwell has in store in the distant future. It means that the SP3 will not be the right device for some people, but it's a great device for most. I think Microsoft did the right move by resetting its baseline for thermal performance. Those of us who were hoping for a gaming experience similar to the SP2 will be disappointed, but I think we're in the minority compared to the larger demographic that the SP3 is targeted to. The SP3 makes a lot of compromises to achieve the incredibly thin form factor, but they're not necessarily bad compromises. From my perspective, Surface Pro 3 is simply arriving at the right balance of thermals and performance - the previous designs aimed too high on the performance curve and required an unreasonably large chassis as a result. Had Microsoft done that from the start we wouldn't have seen any performance regression but rather a steady increase over time. From the very beginning I wanted a lower TDP part in a thinner chassis. While performance regressions aren't ideal, in this case I can appreciate what Microsoft has done. The simple fact is that in becoming a thinner device, Surface Pro 3 inherited more thermal constraints than its predecessors. In games, the difference can be noticeable. Those users upgrading from Surface Pro 2 may notice a regression in performance, particularly when it comes to running prolonged CPU/GPU intensive workloads. Anand summed it up perfectly in his review: I know the thermal throttling is a big issue for a lot of people (my self included), but you need to take it into perspective as well. Hopefully microsoft will eventually comment on this and perhaps increase the thermal threshold? Who knows! Please help out by adding more things to read and look at and feel free to comment here on your own experience with GPU/CPU intensive tasks and thermal throttling. I really hope they fix this throttling and at least let it run 80-85C and not at half the speed at 60-70C. I could run diablo 3 just fine on my Lenovo yoga pro 2 with hd4400. Somewhat playable single player but not in multiplayer rift runs. It is not playable with everything low on 1440x900. Note that the CPU/GPU is at 2.6ghz/1.1ghz for about 2 minutes before it tanks to 1ghz-1.2ghz and the GPU goes down to 600mhz-800mhz. Taken from a thread discussing the issue. Surface Pro 2, but prolonged load cases will likely show a decrease in performance vs. Benchmarks will show an increase in performance due to more aggressive ramping up/down of clock speeds vs. But the big change is I believe Microsoft is more aggressive about reducing CPU and GPU frequencies in Surface Pro 3 compared to Surface Pro 2. For starters, I'm guessing that Intel is helping Microsoft with delivering better binned Haswell ULT and Y series SKUs. Either Surface Pro 3's fan and heatpipe configuration is able to remove heat far better than Surface Pro 2's design could, or the CPU in SP2 doesn't get as warm. The thermal story points us in the right direction. I, like many others here, want to make sure the device will perform adequately to my needs before spending (what is to me) a lot of money.Īt the moment here are the main things I have found about the thermal throttling: So even though it says "high score" it really means "best score".I thought it would be a good idea to post articles, points of interest and comments in one place about the more apparent thermal throttling going on in the Surface Pro 3. * One note regarding the benchmarking tool included. You are not really overclocking your Surface Pro, just disabling throttling and placing it close to Turbo Mode most of the time. The setting I would recommend NOT messing with is voltage. Here are the settings that seem to work best for me. It then runs from your Notification Area as a little stop sign icon. ![]() There is no setting to have it start with Windows so you have to either set that up in Scheduler or manually start it when you want to use it. One benefit I have noticed is that web pages load much faster more consistently. I use it when I am plugged in and turn it off when I need to be on battery for a while. ![]() Basically it allows you to run your Surface Pro at close to Turbo speeds all the time. There is an app that allows you to stop this throttling. Your Surface pro runs a cpu that can throttle back pretty dramatically - down to about 800 mhz. This works well for me but if you brick your rig it's on you. ** Of course, proceed at your own caution.
