QuoteQuad-Channel

Wrong, According to the big AIs / LLMs over at lmarena.ai, LPDDR5X uses 16 bits per channel (never 32 bits), and if it's 16 bits per channel, then "Quad-Channel" would mean that the bandwidth is:
41.6 GB/s = 4 channels * 16 bits per channel * 5200 MT/s / 1000 / 8
41.6 GB/s is obviously incorrect, as AIDA64 memory test measures 70 GB/s.

As a matter of fact, it's 128-bit, one can also state that it's octa-channel (8 * 16 bits).

Desktop DDR5 RAM has 64 bits per channel, so it's different vs LPDDR5X.

If you'd just state that it's 128-bit, then it would be absolutely clear.

83.2 GB/s = 128*5200/1000/8.
The theoretical 83 GB/s, minus the overhead etc., perfectly align with the measured 70 GB/s.

Quote- from 16GB to 32GB RAM (graphic softwares and a LOT of multitasking)

Now we can see how all 16 GB RAM laptops/devices (have) become e-waste with the soldered RAM, accelerated by OS's own LLM AI feature requirements, too.

I am considering to upgrade to this model from my X1C Gen5. My Gen5 i7 is still working very well, but there are two points where I need improvement:

- from 16GB to 32GB RAM (graphic softwares and a LOT of multitasking)
- from FHD resolution, BUT I do need matte display, so UHD is not an option. 2.2K display would be ALMOST workable, but then the 300 nits is the problem. So 2.8K OLED seems an exciting option, but I haven't found a review on this display yet. Therefore, I requested a demo unit with OLED display, and finally I got it today, I started testing of it. The first impression is good, it doesn't look any glossier than old FHD display, but I'll check it outdoor as well. Do you plan to make a detailed review with this display? (If not, maybe I can post comparison pictures, if interested.)

ps1: just as mentioned in the review, the fan spins up often. I'll check whether 1.30 BIOS update would make any improvement.
ps2: keyboard: I fully agree with Benjamin. Keyboard is good, but the shallow key travel is strange after Gen5. At the moment, Gen5 typing experience is more preferred. We'll see it a few days later. On the other hand, the keyboard size is perfect; I didn't fall in love in X1 Nano because of its smaller keyboard. X1C keyboard size is the right one.

I think the T14s gen3 AMD would outperform this on most aspects, with size and weight remain similar. I hope you test it soon.

What a disappointment, Intel 12th gen...
I am typing this on a 5th Gen Carbon, and honestly, I don't really see why I should upgrade. 5 years and no real improvements.

Meanwhile Apple is just marching on with the M1 and now M2...

I have no pwm. On g10 i7 (1920*1200)TOUCH. Being very sensitive (immediately detect pwm on macbooks pro an x1 carbons) can say that surely. Display panel made by Innolux.
