I bought the X12 with the i7-1160G7 and 16GB of ram. About a month later, I had a major device malfunction and Lenovo offered to replace it with the X1 gen 3 tablet with an i7-8650u and same amount of ram (b/c an X12 replacement would take 2 months.

Based on this review, it seems that the X12 with my current i7 configuration is essentially just a waste of money since it's "locked" due to power consumption limits. Do I have that right?

If you had the option, would you keep the X1 replacement? Pros of the X12 are the size, weight, battery life, front camera privacy shutter, thunderbolt 4. Pros for X1 tablet are the screen resolution, performance, and SD card port.

Input, thoughts, advice are welcome. Thanks!

An interesting Windows 10 tablet particularly because of that Thunderbolt 4 port, but I'll wait until the Dell Latitude 7320 Detachable review comes in. Like this Lenovo, the Dell also has Thunderbolt 4 port but also a little compartment to store the stylus á la Microsoft Surface Pro X.

I got one with the 1130g7 and you are restricted to only 9-10W package power when using the graphics. Crazy thing is that it runs at <60c at medium fan speed. Boosts up to 40W. I think the iris xe is almost useless when the whole package can only use 9w.

Hi,
Thanks for the very detailed review as always.

I noticed that there's now the addition of a stylus section of the review, completely absent from previous reviews of 2-in-1s. I'd really hope that the time taken to cover that section is effectively spent, so I'd like to suggest a few improvements regarding the execution:

1. Please only try to draw diagonal straight lines, slowly, when testing for diagonal jitter. Veering off course due to human error largely renders the results unreliable. A ruler might help with standardization, but by choosing a ruler, every subsequent model should be tested with a ruler.

2. Please test cursive handwriting, because one is generally forced to write larger letters on a screen than on paper due to accuracy issues and writing in block font cannot possibly match the speed of cursive. Anybody serious in handwriting with a digitizer should be using cursive, it's also far more sensitive to aggressive smoothing behavior which can sometimes be more detrimental than jitter. Not at all an issue on iPP but more or less an issue on all the N-trig models that I've tried(worse, most don't have any option to change this behavior, or only have a very crude slider). Almost any digitizer can be accurate if you're extra patient with it, there are drawing apps/macros which add immense stabilization to enable perfect curves at painfully slow speeds, only suitable for certain forms of drawing of course, the key differentiator is whether a digitizer is accurate at any speed, which rules out excessive stabilization as a workaround.
Regarding the standardization of testing handwriting, I personally use the pangram "the quick brown fox jumps over the lazy dog", to be both thorough and efficient, just like font files. I'd write it 5-10 times to get stable results from the screen and stylus combo.
I also try to test with my eyes closed, because the varying lag in inking could mess up your handwriting if you see it happen(you could get used to it but it takes quite a few days in my experience), a longer lag(basically anything longer than iPP's) may mislead you about where your pen tip is during the moment you write. Speaking of which, setting the device to whatever mode provides maximum performance could minimize inking lag.
Of course, writing speed affects the behavior of stabilization, so I'd recommend trying to write at the same speed across devices, but that's hard to gauge or control. A mere thought at this moment.

3. Testing for parallax can also help, my new Spectre x360 14 has better accuracy and lower stabilization overall than my XPS 13 2N1, but strangely the parallax remains at ~1.5-2mm to the left of my tip no matter how I angle the stylus(this is with a certain film applied, which may not be factory default behavior, the film also seems to slightly increase smoothing, which to me is a bad thing, but it does protect the screen and greatly improves writing experience with a paper-like texture). Parallax is a minor issue though and Windows calibration may reduce it enough to make it a non-issue.

Finally, your test seems to be done on the UWP Onenote, so it would be best to do subsequent tests all on the same app. Using MS paint for example will get very different results.

What a crap device!

This "Intel Core i7-1160G7 is a Tiger Lake processor of the UP4 series" is slower than the "old X1 Tablet Gen 3" - that's the Lenovo ThinkPad X1 Tablet 2018!!!! That was reviewed in Jan 2019! Its slower than the Microsoft Surface Pro's i5 too!

Why don't Intel just shut up shop instead of conning people of money! Notebookchat should also state this in BOLD & UPFRONT instead of recommending this at all to please Intel/Lenovo. Everything "good" about this device should have a big ASTERISK attached to it!

This kind of crap just makes consumers like me so mad ... AAARGH!

It was Lenovo who chose to use a version with lower power limit. Intel still makes standard ULV processors. I was too lazy to check all the comparisons (it looks like G3 is missing in most of the CPU comparisons, like they weren't performed on it), but looking at Cinebench R15, it scores more than its predecessor. It clearly has a lower long term power limit, but the first run is significantly better and it takes seven runs of CB15 for them to cross (in stock configuration, not undervolted). If it's worse than its predecessor, then the fault lies with Lenovo, I'm afraid. After all, that Surface has Intel as well.

Hi, thanks for the in-depth review as always.

I hope in the future you could bring back the individual Prime95 and FurMark stress test so that we can have a better idea of the performance of the laptop under common situation. Does the X12 also throttle to 800MHz when put on pure CPU load?

After years of ThinkPad tablet abstinence, Lenovo returns to the 2-in-1 market with the new Lenovo ThinkPad X12 Detachable Gen 1. The Lenovo X12 Tablet manages to impress us in our test - it turns out to be a worthy competitor to the Microsoft Surface Pro 7.
