Lenovo ThinkPad P53 Lenovo The ThinkPad P53 represents the best that Lenovo has to offer in a 15.6\" workstation. The machine is bulky, but it packs a ton of power into a reasonably portable case. While I can appreciate the insane performance housed within the chassis, the high CPU/GPU operating temperatures and the occasional performance glitches under stress are concerning. Perhaps tuning the fan curve would help control component temperatures. Lenovo ThinkPad P53 The ThinkPad P53 represents the best that Lenovo has to offer in a 15.6" workstation.

    Nice review! This site is the first one (in English) to actually publish a well thought out in depth review. Minus the screen information.

    Anywho, I just received my P53. 9850h, RTX5000, 4k Oled, 16GB ram, with 512GB SSD. I'm noticing similar thermal issues (and at times worst).

    Also there seems to be a bug that throttles the machine (cpu & gpu) to the battery power levels if the machine is moved. My CPU idles at 63c and quickly goes to 97c where it throttles.

    My RTX5000 cannot seem to run at its full speed. My time spy score was 5983 with a – 110mv undervolt.

    While I like everything else about the laptop including the design, keyboard, ir camera, fingerprint sensor, and the thunderbolt ports in rear. I'm thinking of sending it back. It performs worst then the thin and light laptops like the GS65.

    Question : based off your review I also ordered a MSI GE75. While loud, it is almost the same size as the P53 but with the full 150w 2080.

    Why did lenovo decide to create a thick machine that is slower than other thick machines by using the internals of thin and lights (like the razer blade studio) and still have it perform worst?

      Thanks for the kind words, Derrell. It kills me that I don't have the proper tools to evaluate the screen, but c'est la vie.
      I believe that Andrei experienced a similar bug with the P73. IIRC, he noticed that performance took a hit or odd behavior occurred when the machine was moved. I'd check out that review for more details, but it seems endemic to the line. I didn't notice anything like that, but I left the machine flat on a table for most of my time with it.
      So the RTX 5000 in the P53 is the 80 Watt Max-Q version, although you won't find that on the laptop product page. We had to ask directly for that information. That's my guess as to why you're seeing the bad numbers in TS. It's baffling as to why Lenovo used such a low wattage GPU in suck a thick chassis, but considering the poor thermal management, it's probably all they could muster.
      IIRC, the P52 and P72 had similar performance issues. What's baffling is that Lenovo didn't listen to customer complaints about thermals and poor performance from last year and fix anything. This device really makes me think Lenovo phoned it in on the P53, but that's my personal opinion.
      The GE75 is an interesting alternative. You get the benefit of a full-powered RTX 2080 AND a 144 Hz screen, but I've read that thermal throttling is pretty beastly on it. Keep an eye out for inconsistent performance and dropped frames when gaming, and be sure to check for backlight bleed on that machine. Otherwise, I think it's a fine device. I personally like MSI laptops because of their keyboards and overall good value.

      Hi, that's the Active Protection kicking in. The system uses the accelerometer to kill certain functions when the laptop is moved, but I found it way too aggressive on the P73. In the past you could deactivate this from the settings, it's no longer possible right now on the P53, but I think it might be added into a later update. I've been told they are aware of this aspect and working on it.

    Thanks for the replies. I read the P73 review as well. This is very disappointing, I didn't know about similar issues on the P52/P72.

    I would be fine if my P53 performed as well as yours. I took the advice of Andrei and elevated the laptop which increased my time spy score to 6400, with mostly cpu gains.

    My P53 was bought on sale for under $2400 including taxes. So performance the same as the razor blade studio for that price is worth it.

    As far as my GE75, it scores around 9300 in time spy with a -150mv on the cpu. I haven't seen any thermal issues with the laptop. The cpu runs around 80c with 100% load at 3.6ghz, and the gpu around 76c.

    One of these laptops is going back, as of now I'm heavily leaning toward keeping the GE75. While I'm not much of a gamer, it seems that the only powerful laptops are gaming laptops.

    Again thanks for the review. It really validated my experiences so far.
