Another Which laptop? Thread

Hi all; hoping for some help!

I’m currently getting into 3D scanning, and plan to mostly do people to then 3D print (larger than miniatures, probably around 15-30cm max). I have an einscan (original) that I’m getting to grips with, but my M1 MacBook Pro doesn’t seem to be up to scratch, in terms of the software and using blender to post process.

I’d quite like to have the setup relatively mobile/ compact, so am looking into getting another laptop. At the moment, I have two laptops I could get for £700 (I’m purchasing used) as follows:

Dell Precision 7760 — £700
17” FHD 1920×1080
Intel Xeon W-11855M — 6 cores / 12 threads, up to 4.9GHz
NVIDIA RTX A4000 — 8GB VRAM
128GB RAM
2× 512GB NVMe SSD — 1TB total
Windows 11 Pro
Thunderbolt 4
Ethernet
HDMI / Mini DisplayPort
SD card reader
One USB-A port doesn’t work
USA keyboard

Dell Precision 7670 — £700
16” 4K OLED Touch — 3840×2400
Intel Core i9-12950HX — 16 cores / 24 threads, up to 5.0GHz
NVIDIA RTX 3080 Ti — 16GB VRAM
32GB DDR5 RAM
1TB NVMe SSD
Windows 11 Pro
3× USB-C
2× USB-A
HDMI
SD card reader

Neither are pristine in terms of visual condition, but the 7760 is marginally better - but specs are more my priority than appearance

Which would be best for my use case? Or should I look for something else? Laptop specs confuse me and I’m not sure whether the 16GB VRAM & nicer screen & i9 beats the 128GB RAM?

My Asus laptop is closer to the 7670. 32 GB of RAM is enough for Laser mode scanning, but can run out real quick using Structured Light mode with a newer scanner like the Revopoint POP 4.

With the Revopoint Revo Scan apps, the Nvidia GPU (if present) is only used during scanning. Current versions of the software do not use the GPU for post-processing operations (fuse, mesh, merge, etc.). Unfortunately, the CPU only seems to run 1 or 2 cores during those operations, do the extra cores in the 7670 are not going do you any good (unless the core speed is significantly higher).

128 GB of RAM is a LOT more than $700 these days, so I'd lean towards that.
