I am programming 3D processing software therefore, the Optimized mode seems to be the best for me.Īs a future work, I will run a CPU and GPU benchmark, to check if this behavior is consistent.Welcome to /r/Dell. Whereas, Ultra Performance mode is better for long multi core sustained tasks like: video encoding, 3D rendering. The Optimized mode seems better suited to burst loads like: internet browsing and programming. In these conditions, I do not expect the Intel Core i9-10885H to deliver significantly better performances, unless the binning makes this chip more power efficient. Same problem on a multi core load in Ultra Performance mode, the temperature stays at 100☌ and limits the overall performance of the CPU. The limiting factor is the temperature, which get to 100☌ on one core. Regarding thermal limitations, we can see that on a single core load, the CPU cannot reach 5.1 GHz, which is its maximum Turbo frequency. Even if it is not clearly noticeable on this benchmark, on a longer task, 45 vs 60 watts would make a significant difference. Multi core CPU performance however is better in Ultra Performance mode. Single core CPU performance seems to be the same in both modes, so for typical single core tasks, the power management mode does not matter. The overall power consumption was below 100 watts and I did not notice any battery drain during this test on my model. For reference, I ran the same test on the computer when it was brand new, and got a score of 3 589 (4% better). The usual software was running on the computer: OneDrive, Skype, Norton, etc… This may negatively impact performances, but at the same time, it’s more representative of my daily use. No trackpad or speaker issue, the laptop just works!Īs can be seen on the graphs, the power delivery works in two phases: after a burst period of about 45 seconds at 90 watts, the power plateaus out in a steady state at 45 watts.Īs can be seen on the graphs, the power delivery works in two phases: after a burst period of about 45 seconds at 80 watts, the power plateaus out in a steady state at 60 watts.ĭuring the test, the laptop was plugged in, sitting on a table with the screen open at a 90° angle. Intel Core i7-10875H (8 cores, up to 5.1 GHz).This software only asses the multi-core and single-core performances of the CPU, i.e., no GPU involved. I’m actually interested in these two last modes how do they compare? Which one is the best for my use case?įor benchmarking, I used Cinebench R20, which measures the time needed to render a 3D scene. Finally, Ultra Performance mode increases processor and fan speed for more performances. Optimized mode seeks a balance between performance, noise and temperature. Cool and Quiet modes reduce performances to either keep the laptop cool or silent, I won’t review these modes, as I am interested in having at least acceptable performances. Dell provides a software that allows switching between different power management modes: Optimized, Cool, Quiet and Ultra Performance.Įach of those have a different goal. I recently purchased a Dell XPS 17 laptop, and since there is a lot of controversy regarding thermal management on this model, I wanted to benchmark it.
