![]() The heatsink and heatpipes and fans do an amazing job on cooling this beast, even when it is under constant stress.Īfter performing a variety of ThinkPad P15 benchmarks, I am impressed by what this machine can do. The “Intelligent cooling” is a great addition. ConclusionsĪll in all, I am satisfied with the performance of the ThinkPad P15. How much and what effect it had I will summarize in my repaste article, due in a few weeks. My repaste improved these values ever so slightly. First, what was before the repaste operation. These apps perform just as well in the balanced profile. This means that some apps that use the CPU only partially will still push the computer to become noisy and hot. In these modes, even a small need for performance drives the CPU up to the max, and from there it is hard to get it to cool back. The ultra mode pushes things a tiny bit further that the regulat performance mode. In both modes the fans will start going fast and loud sooner or later. While Lenovo added a separate ultra performance mode, I find it pretty similar to performance mode. As a result this has been my preferred operation mode during less demanding work, like writing documents or working with presentations. In this mode, the fans are barely audible, and even extended periods of stress will not cause noise. The computer looses a little performance in exchange for being cool and silent. Because in this case speed equals heat, this means it will also not heat up that much. What this means is, that it will not go too fast. On balanced mode, the CPU is held back by power limits. If these switches could happen automatically, that would be intelligent! How the thermals work then? But if I am then just writing some code, before it is time to build and compile again it might be good to switch back to balanced mode. Similarly if I start developing and compiling I need performance mode for a while. When I then start to play with Docker containers or VMs, I need to manually switch to performance mode, otherwise the CPU will just be too slow. If I am writing an article like this one, I have to manually put it into balanced mode, or otherwise the fans will be spinning faster than needed and the CPU produces more heat than needed. They are well thought out, and I do like what they bring to the table very much!īut I would prefer if they would change intelligently on their own. There is nothing intelligent about them IMHO, they are just power profiles. Why they are called intelligent, I don’t know. ![]() User benchmark and PassMarkįollow the link below to check out details about the User benchmark results for the ThinkPad P15: ![]() When stressing it still goes to 100C even after changing the thermal paste, but there are fewer dips and max frequency is slightly higher. The CPU is also running a few degrees cooler after the repaste when not stressed but has a continuous workload. ![]() The CPU does around 75C for the graphics test and of course maxes out at 100C when doing the CPU stress test. This used to be about 65C before I repasted the GPU and CPU coolers. While running graphics benchmarks and the GPU is working on full load it does so by going to about 60C. The scores would suggest that in games at least, the Quadro RTX 4000 Max-Q is a little bit below the GeForce RTX 2070 Max-Q. This is probably because of the Quadro RTX 4000 is not primarily geared towards games, and is running at a lower clock speed compare to gaming geared GeForce RTX cards. The results indicate a strong CPU score, but not that strong graphics score. The bigger leap is achieved by having more cores available. The 10th gen H series CPU is a slight upgrade in single core performance over the 8th gen. But do remember, that the ThinkPad P52 has a 6 core CPU, which explains the difference in the multi core results. I also included results from the ThinkPad P52 for the R20 benchmark. I ran three different CineBench versions on the ThinkPad P15. Let us now dive into the different performance metrics that benchmarks provide us. As far as I can tell, in everyday use, the drives perform really well. I am a little perplexed about why there is such a big difference in random 4k reads and writes, but it might be something specific to these drives. ![]()
