Re:ThinkPad X1 Extreme Generation 4 Technical Review

2021-07-28, 9:35 AM

Hello @richk ,

 

I gave your review a second read and yes, I was reading it too hastily.

You indeed mentioned that only 3050Ti would not require a vapor chamber, thus preserving a 2nd SSD slot and possibly WWAN card.

 

I wonder if they will use MUX switch, or traditional electronic circuits for GPU switching ? Would you happen to know anything about it ?

I would also like to know about the GPU management. If it uses some form of advanced optimus, that means the dGPU is not needed when an external monitor is plugged in for productivity. This means that the M14 portable monitor would be a viable solution that would not cause insane battery drain when on the go.

 

Rich, can you try to test certain GPU settings and maybe show some screenshots of the Vantage center? Also, plugging in external monitors via HDMI or thunderbolt?

Have you done any gaming on this unit.  I'm looking for a new laptop for productivity I currently have the razor studio which has the RTX 5000. But I do enjoy some casual gaming every now and then.

@jg2010 I'm the wrong guy to ask about games. I have no knowledge or experience. Sorry

Hi Rich, thanks to you I am about to order the P1 Gen 4. I wanted to know the performance on battery power? Specifically Cinebench R23 or any other benchmarking tools to compare plugged-in vs unplugged performance.

 

Thanks again.

The P1 offers the 3070 and 3080. With that being said...what are the differences between the x1 and p1 series now? I believe prior to the gen 4 models...the P1 series did not come with the 20X or 30X series GPU. The P1 Gen 4 is available to purchase whereas the X1 Gen 4 is not. Again, you can get the 3080 on the P1 Gen 4. IS there a reason to not go ahead with the P1 and wait for the X1? Do you pay more for the P1 because it is considered a workstation and the X1 is not? Any thoughts are appreciated.

 

As of now, I am wanting to purchase the 11950H along with the 3080 gpu.  I do not want to pay more for the P1 if the X1 with the same configuration will be cheaper. 

 

 

Thank you

@bccc First, let me say that Cinebench is not a good example of the types of tasks you would choose to run on battery power.  I did no battery test under that kind of load, but I would expect that 16 threads running at the same time under full load would drain the battery fairly quickly.  In my review, I did a non-scientific test by watching a movie and checking the battery level.  I thought I might want to watch a movie on an airplane and there might not be a socket that could deal with my 230-watt power adapter, so, for me, that was a realistic thing to test.  

 

Having said that, when I run tools like Cinebench, I expect there will be variations in scores so I run several times and take a score in the middle.  Scores can vary by a few percent.  In the case of my response here, I only ran on battery 3 times because I got tired of sitting there, and the machine would try to sleep if I walked away.  The scores I got were 10783, 10950 and 11096.

 

Please note that with a new model, software and firmware frequently change, which may affect results.  Since I wrote the review, I got a newer version of the BIOS and a newer power management driver.  That may or may not have affected my scores.  Also, yesterday, Windows Update pushed a new version of the NVIDIA drivers.  That would not affect Cinebench but might affect other tests.

I am wondering the same thing here. 

Also does anyone have any insight into a rough difference in battery gains from going from UHD+ to a QHD panel?  4K sounds great in practice but so many apps still have issues with properly scaling.
