以下来自Reddit一用户的简单测评，顶配，非性能模式55～60度，性能模式80～100度，你这才10750H+T1000，按理说散热绰绰有余了啊，风扇转速问题？？

I have used my brand new Lenovo ThinkPad P15 Gen 1 for a month now.
Here is the full specification:
Intel(R) Xeon(R) W-10885M Base Speed: 2.40 GHz (More on this later)
128 GB (4x32 GB) DDR4 RAM 2933 MHz ECC SO-DIMM
2x2TB (4 TB) SSD M.2 2280 NVMe TLC OPAL (RAID 0)
UHD OLED Touchscreen Monitor
Nvidia(R) Quadro RTX 5000 16 GB 256-bit Max-Q
WAN: Fibocom L860-GL 4G LTE CAT16
IR 720p CameraWindows 10 Pro for Workstation
All the optional slots (smart card reader, etc.)
3 Yrs Premier Support Upgrade + Accidental Damage Protection + Keep Your Drive + International Services + Sealed Battery + Tech Install CRU

My first impression
I expect it to be quite heavy, and it does not disappoint at all. I think mine is easily over 3 kg (it is starting at 2.74kg according to its PSREF document). It is heavy, but to be fair, it is NOT uncomfortably heavy to carry even when it is inside a sturdy, nicely cushioned backpack of your choice. The cover material looks fantastically normal (it's black, it's matte, it's boring-ish) and quite easy to clean from oily fingerprints. I guess it's pretty much expected from a mixture of Glass Fiber Reinforced Plastic/GFRP (50%) + Polyphenylene sulphide/PPS tested with ASTM D695 standard (50%) for the cover material.
The monitor looks totally fine, colour-crisp (I guess expected with factory colour calibrated monitor; I can definitely adjust the colour settings from the X-Rite Color Assistant; pre-installed), and reasonably bright with 400 nits (I don't think my eyes can handle fully blasted 600 nits from the non-touchscreen option when used indoors). I am delighted choosing this option since I use the touchscreen feature once in a while with the Lenovo Pen*. As I was using the touchscreen monitor (using my other Lenovo Pen from my X1 Yoga), I don't see any major problems as I was writing/drawing comfortably on the monitor.
Performance-wise, this laptop promise ultra-performance option (to turn it on, put your battery performance to the maximum best performance, and it's ready to go). Here is what I get from the Processor power:
Base clock: 2.40 GHz. I rarely saw my laptop working at this performance clock.
Average clock: 3.40-3.50 GHz. This is the speed range I got from using the battery as well as plugged-in with "Best Battery Life" performance option.
Ultra-Performance clock: 4.70-4.80 GHz. Even during a benchmark, I still could not unleash its maximum ultra-performance that Intel promised (read: marketed) at 5.30 GHz. Please let me know in the comments below on how to try to utilise the maximum ultra frequency above 5.0 GHz mark.
I used two different (basic) benchmarks: PerformanceTest 10.0 Evaluation Edition by PassMark and PC Mark 10 Basic Edition. My apologies for not using the more serious ones, but I am not an avid benchmark-tester person, so I only use these scores for basic reference.
PassMark Test Results
As you can see, the 2D Graphics Marks scored quite low (I have no clue on how to improve it; I had made sure in the Nvidia Control Panel that I prefer to use Quadro RTX 5000 Max-Q as my primary card rather than using the Intel(R) UHD Graphics P630, and still I can't improve that score. I am quite satisfied with the rest of the scores, especially my CPU Mark at 18,401. The current average score for the processor (sample: 14) is at 17,240, which make my score 6.73% outperforming the average.
For the PCMark 10, the laptop scores at 5,847. Sorry I did not save the details (i.e. Essentials, Productivity, and Digital Content Creation scores) for this test (silly me, I did not screenshot them), but it should give anyone a fundamental idea (PCMark 10 recommends scores of 4100, 4500, and 3450 or higher for Essential/General PC Use, Productivity/Typical Office Work, and Digital Content Creation scores respectively).
I also use the Lenovo Thunderbolt 3 Workstation Docking, so I pretty much do not use my battery that often (it's still pretty much covid-19 epidemic in my area and everywhere around the world, so realistically I do not really rely much on the battery life to do my work), but I can tell you that expect for just a shy of 1-hour battery life at ultra-performance mode and around 2.0-2.5 hours maximum at best battery life (note: I used a reasonable level of monitor brightness and sitting outside in my balcony to do my typical MS Office works with some R or Python and three Google Chrome windows with at least 20-25 tabs for each window when I tested it).
When you buy this laptop, it really does not make any practical sense if you expect this beast to run for 8 hours on a battery so you can carry it around outside on a park bench running your ML algorithms or editing your videos. It is called a workstation laptop for a reason. However, 2-hour minimum battery life should give you ample time to move around looking for a charging spot (another coffee shop, or another seat with a working power cord at your favourite library).
In terms of fans speed and sound, I rarely hear it cranking up under the 'Best Battery Life', once in a while under 'Balanced' mode, and almost constantly under 'Ultra-Performance' mode. Is it annoying, or really annoying? Not really, to be honest. It just became a background sound for me (I am not sure how much dBs the fans really are), as I used to work in a quite noisy environment. However, as long as you have a reasonably good quality of noise-cancelling headphones, it will do the trick just fine.
How about the heat? I tried to put the laptop on my lap while using the Ultra-Performance for 30 minutes straight, and the heat is noticeable, although not as bad as I thought it would be. Perhaps it really is an improvement from P53. How about the CPU temperature? On average, it works just fine around 55-60 degrees Celcius under the 'Best Battery Life' mode. I haven't tried to push it until it heats up around 95 degrees Celcius on average or more, but I definitely have used it slightly above the 80 degrees Celcius mark for an hour or two. Typing on the keyboard was not problematic for me after getting the laptop heated up when using the ultra-performance mode, so that was a good sign, I guess.
It will take at least a few months to see whether these experiences are consistent from time to time. Hopefully, this laptop will take me through my heavy-duty research works for a VERY long time as I was expecting to use it for at least 7 years down the road. Cheers to another 6 years and 11 months to the future!
* There was a slight glitch with the delivery of the pen. It was supposedly inside the box together with the laptop, but it went missing. After going on a few emails back and forth with the customer service trying to convince them that it was legitly missing from the box, they had sent it to me a few days ago and now pending for the courier service journey. I have heard unpleasant stories about the Lenovo CS, but for this case, they served quite well.
Edit: As I finish editing this post, my Lenovo Pen Pro was just delivered by the UPS courier guy. I quickly went to test the Pen Pro, and it was definitely a better experience than using the X1 Yoga Pen when I write/draw on the monitor screen. I am not quite sure whether it is the Pen that matters or the monitor surface has something to do with it, but I am more inclined to the former rather than later. |
