Is this an advertisement?
Yes, it's an ad. Basically the Lunar Lake option is a high single core perf CPU that is pretty bad for anything other than checking emails and web browsing. We're in 2025 and outlets still haven't found a way to properly test multitasking.
https://en.wikipedia.org/wiki/Lunar_Lake
According to this, all Lunar Lake CPUs have 4 performance and 4 economy cores; none have a single core.
You're being purposefully dense, it had a misplaced word. It's fixed now.
I looked up the CPU and its faster than the R7 3700x I game and edit videos on in my desktop..
Let's see: Blender, for the BMW27 the 3700x is ~30% faster.
In notebookcheck's own site, you can add a 3700x test (together with a Vega64) and see that outside of single core synthetic results, in every multi-core real world scenario, the 3700x trounces the Lunar lake CPU, even though it's several nodes behind in density (7nm vs 3nm) and it is 6 years older, has much less memory bandwidth...
I highly doubt the 238v is faster than the 3700x at anything other than browsing the web or other single core loads...
edit: Unless one looks at userbenchmarks (if that shithole still exists), in userbenchmarks even the 6700k is better than a 9800x3D.
I'm just saying it absolutely will do most tasks without issue, since my 3700x doesnt struggle at all with any normal every day task.
And my point is the 3700x performs well in multicore CPU loads, lunar lake, likely less so, when taking the benches in consideration. This reflects in its multitasking capability.
What a poor take. I’ve been trying g to find the right balance between performance, battery, and heat/sound for business use. Intels previous gen under performed, AMD ran hot, and neither were good with battery.
Jumping from 10hrs to 18hrs in testing is huge, with real world use likely going from 4-8 hrs. Getting an all-day battery is a win that only Apple and snapdragon have been able to do.
Oh look, the OP that posted the ad doubles down on the false expectations published in the ad.
Lunar lake guzzles energy when using several programs at the time and performs worse that even Arrow lake in the battery department once this is the case. If you put a lid on it and use the low perf mode, you revert to performance from half a decade ago. At that point one is much better served by a macbook air. The only saving grace of lunar lake is the performant, low power iGPU. The single reason to use an x86 laptop is compatibility with professional software like catya etc, Lunar lake is trash tier in anything remotely useful, which begs the question: why would anyone choose Lunar Lake over snapdragon or Mx laptops then?
Nope. The jump in battery life is impressive.
Not when it comes with the huge downside of non upgradeable RAM. I will carry around a huge power bank before I buy a laptop with soldered RAM.
I carry a ~300 Wh power bank with my laptop.

They also have a less-elaborate, smaller, lighter, less-expensive ~200 Wh model that's probably more actually-practical:

Note that you can't take anything over 100 Wh on a flight in the US. I also have a 100 Wh power bank that I keep around for flights.
32gb is fine for most
I don't see many users upgrading the memory on a laptop like this either but would criticize soldered RAM based on the aspect of repairability. T14s are often used in business which means hundreds of machines handled by IT departments. Boards will die and technicians will throw them out including the RAM. Now granted most companies don't bother with hardware repairs anyway but somewhere down the chain someone will have these machines on their workbench and the easier it is to fix them up the better.
640K ought to be enough for anybody.
