QuoteQuad Channel
100% sure it's dual-channel, also confirmed by AIDA64' 87564 MB/s reading.
You can also calculate it: 2[dual-channel]*64[bit]*8533[MT/s]/8[bit->Byte]/1000[MB->GB] = 136 GB/s theoretical maximum, and 70% to 95% of that is what is always being measured.

In laptops, quad-channel aka 256-bit wide memory bus chips are: AMD's Strix Halo and APPLE's M Pro series, the M non-Pro are the usual 128-bit, like the far majority of the laptops and desktop PCs.

32 GB RAM max is a big bust, but Intel is to blame here rather than Lenovo.  Let's hope Intel addresses this issue as 32 GB is barely acceptable these days.
^ This. With only up to 32 GB RAM option and soldered at that, this laptop will age like milk. And the 8533 MT/s won't help at all. 32 GB minus 8 GB for the OS+etc. leaves 24 GB RAM and this is not enough to self-host the actually usable LLMs out there, even at the maximum usable quant (typically Q4_K_M). 48 GB or 64 GB RAM options required. (and ideally +~10 GB more for things like Gpt-Oss-120B)

Can one charge from BOTH Thunderbolt USB-C ports? If yes, then one can continue using this even if one USB-C port gets broken.
Otherwise this is a HUGE disadvantage, don't buy for business-critical use!!
Yes, possible to charge on both, even if one gets broken.

Were the power consumption tests done at 60Hz or 120Hz refresh rate?

And along those lines...  Any guesses as to how much impact on battery/power the new VRR 30-120Hz display will have?  I'm tempted to buy the old non-VRR version that's discounted as a pre-built model right now - but if waiting for a discounted VRR model means an extra hour or more of battery - then that's a big deal.

Thanks, I'll be keeping an eye out then!

Definitely planned, but no promises when.

@Benjamin Herzig: Any chance we'll be seeing an updated (or second) review of the Thinkpad X1 Carbon Gen 13 Aura Edition that tests the new hardware options, i.e. the new processors, new RAM, new screens, updated webcam, 5G, ...?

Lenovo already announced the 2-in-1 equivalent of the X1 Carbon Gen 13.

Sadly, you lose the benefit of the low weight there, as the X1 2-in-1 uses an heavier aluminum chassis.
Very nice.

Weight does not disturb me, I used to carry a Thinkpad P51.

I switched to ultraportable devices due to battery life.

It could be a negative for some users of course.

I also see from your post that you linked that the displays on this device are expected to be 500 nits.  That might be (barely) sufficient for outdoor use.

Because "most" includes every cheap device. If, however, one compares to Windows devices with Nvidia dGPU and related software usage, Windows / Linux devices have a good chance to wipe Macbooks.

Looks quite good.

Needs a brighter display so that it can be used outside in full sunlight.  With any luck one of the IPS displays available in 2025 provides that.  My current Thinkpad P16S (display also rated for 400 nits) is unable to do this.

WWAN option is also required.  Lenovo is historically solid on this, so I expect it to arrive next year.

Quote from: Ando on December 15, 2024, 00:43:30I have a quick question.  Currently, I am using a 14-inch MacBook with an M3 Pro chip and 36GB of RAM. Overall, it is an outstanding device however, in my personal experience, while macOS is good it does not feel as functional as Windows.

...

Should I consider a device with a Snapdragon X Plus/Elite, Lunar Lake 258V or 288V, or Ryzen AI 9 370 chipset?  Or, would it be wiser to retain my MacBook for another year or two until newer AMD Ryzen, Intel, or Snapdragon X chipsets are available?

Your Macbook is going to be better than most Windows in terms of performance, battery life, functionality, and pretty much any other metric.  Windows 11 is a shitshow.  ESPECIALLY if you are coming over from a Macbook and you are anywhere in their ecosystem.  I would go Linux before going Windows, although with your workload that would be challenging.

Stick with what you got.  And I say this as someone who really doesn't like Apple's ecosystem or marketing.  I will readily admit they just plain make better devices for people that are in their ecosystem and don't tinker much.  Nothing you have listed would benefit from a migration to x86 and certainly not Snapdragon with it's compatibility layer issues.

Quote from: Mehmet on December 18, 2024, 19:55:16Are the results of the battery test showing the OLED screen running at 120 Hz or at 60 Hz? And how much of a difference would a switch from 120 to 60 or vice versa make?

"We ran the X1 Carbon through the Wi-Fi test with dark mode and the faster 120 Hz refresh rate at maximum screen brightness, and it achieved almost the same runtime as when running in the lower-brightness setting with 60 Hz mode and no dark mode. Upwards of 12 hours of runtime could potentially be achievable here, if all the power saving methods (lower brightness, 60 Hz refresh rate, dark mode) are combined."

Thanks for the excellent review. I am a fan of X1 Carbon (I am on my second one). The battery life is very important to me and this unit seems to have really improved in that area compared to the previous three generations. I have one question though. Are the results of the battery test showing the OLED screen running at 120 Hz or at 60 Hz? And how much of a difference would a switch from 120 to 60 or vice versa make?

Thanks again.
