You are correct, I do indeed.
So I have the T14s Gen3 AMD, have had it for CLOSE to a year now.
I also hae the T14 (no S) Gen3 Intel, have had it for just over a month.
CURRENTLY, they’re both actually running the same OS (OpenSUSE Tumbleweed) so they’ve got exactly the same packages installed outside of AMD/Intel differences.
The T14s AMD DOES have the 400-nit LCD and a Ryzen 7 6850U, while the T14 Intel has the inferior 300-nit LCD, and only has a i5, which definitely does impact battery life, but not drastically (in a week the T14 Intel should have the 400-nit LCD too, it’s on it’s way to me).
The only other stat of consequence here, is the T14 is a 52.5 WH battery, while the T14s does get a 57 WH battery. Not drastic difference, but again, 4.5 WH will have an impact.
So the T14s DID experience battery drain when I first got it. Luckily, unlike the A485 they fixed it with either the first or second BIOS update they released. Since then it’s ran like a champion, and running with 40% brightness and doing nothing more strenuous than surfing the internet I can JUST ABOUT get 9 hours. Given how thin and light this thing is, I’m fairly impressed.
The T14s is the more powerful system overall. However, it’s not by very much. Quite frankly, that Alder lake Mobile is a FAST MoFo. Beats most of my PRIOR R7’s in benchmarks!!! And even with the 6000-series, it manages to beat it single threaded benchmarks, but loses I think due to being hampered with DDR 4800 whereas the AMD has the LPDDR 6400 when doing highly multithreaded tasks.
But battery life…another story. I can get just over 5 hours on the Intel with the same usage and brightness set to 55% (resulting in about the same overall brightness level for the LCD’s while working). Massively less efficient. I expect the 400-nit LCD will be able to help probably 1/2 hour, 45 minutes additional runtime, but I doubt more than that.
So there’s the $.50 review of these compared with Linux.
If you get the intel, it requires the sof-firmware package for sound. I had never owned anything that required that before, and took me longer to figure out than I’m proud to admit.
