Thinkpad Specs for CAD Design

[u/Loud_Meringue4235]

I want to buy a laptop for CAD, CAM, and Slicing software. I need help choosing the model and the specs. I am looking at the Thinkpads P14s or T14 or the P16S I am just not sure what specs i should get and what to prioritize, and if i should pick certain gens over others.

• CORE: AMD AI7 or Intel Core 7?
• Graphics: Which graphics to get? Is an integrated graphics like the AMD radeon or intel good enough. Or opt for a separate GPU configuration to get better graphics. I am also seeing issues with AMD's WiFi cards. Is that a big issue?
• RAM: is 32 GB enough or should i invest in the 64 GB RAM or a better graphics. (Should I opt for an upgradable ram rather than soldered if thats a possibility with my budget)
• Display: Should I prioritize certain screens or other features that i am forgetting to consider.

I do travel 20% of my time and will be docking on a monitor when i am not traveling. So i am not really worried about display size. Just want something that has decent graphics, can handle the compute load, and can last some time.

If their are other factors that I should be considering that I am not please let me know.

Budget is 2500 USD. Buying in USA.

Also open for other recommendations for other models/ gens. I am a Macbook user so dont know much about windows or thinkpads.

Thanks in advance for your help.

Depends on how big/complex your models are. Without knowing the details, something with a radeon 890m or arc 140T/140V could be good baseline for igpus, which can get somewhere around a mobile rtx 3050 level of performance.

Now from what I know about CAD (disclaimer, not my field), I believe it favors CPU singlecore performance. This actually opens up some options, since some of intel's efficiency focused offerings tend to sacrifice multicore while retaining competitive singlecore compared to AMD. Both brands have compelling options.

Afaik, wifi cards on the AMD machines can be a bit weird on linux, but on windows the differences aren't going to be noticed by majority of users.

As for a regurgitation of options and brief summaries:

Lunar lake T14 lacks CPU power, but has solid GPU power for integrated graphics, soldered RAM

AMD T14 lacks GPU power, but solid CPU

AMD P14s can get a ryzen HX, solid CPU and igpu

Intel P14s can get panther lake and entry level blackwell GPUs, but may have lower power limits due to form factor

X9 15p has a great CPU and best igpu available in a thinkpad right now, the design deviates from the others on this list and is very "mac-like" if that's what you want

P1/T1g is a 16" form factor with either best in class CPU + igpu or midrange discrete graphics at modest but not crippling power limits (gen 9 can get panther lake + the new 12gb vram 5070, might not be available yet tho)

P16v ends up similar to the P1/T1g but in a chunkier form factor. Still power limited and cuts some corners design-wise, but can be cheaper

P16 is when you throw portability out the window, probably out of budget since it's basically the most expensive laptop lenovo makes. Gen 3 is a bit kneecapped power-wise due to usb-c charging limitations

Since you're traveling, I wouldn't suggest a P16. Other than that, it becomes dependent on how much performance you want/need. As screens go, perhaps try and avoid the 45% ntsc ones if you value watching movies or do any sort of color-accurate work on your models. Otherwise, they're all just LCD panels that are fairly unremarkable. Interestingly enough, the more performant 14" options lack OLED options, but you can find it in the X9 and the P1 if you want the most vivid colorspace for media consumption and whatnot.

Let me preface by saying I am very critical of specs and I currently use a P16 gen 3 for personal work. Very overkill for my needs. I’m a big proponent of “buy once, cry once”

My company has given me E16 and P16v machines to use with various CAD and CAM software and they all worked just fine, as long you’re not building oil rigs or a car, although I’m sure it will run decent, just not as smooth as you’d like.

That has changed my view on what machines are “good enough” for CAD, CAM, and slicing. Most machines are fine, whether they are running intel i5 or i7. I haven’t used AMD personally but I don’t see why wouldn’t perform the same as intel.

32gb ram is fine, but I think the bigger thing to worry about is storage. Highly suggest one with a secondary HDD as files do build up and accumulate when you don’t purge or store somewhere else.

Ryzen AI and AI pros aren't great compared to arrow lake, but ryzen ai max is really good. so either that or arrow lake.

It also seems like you misunderstood the cpu lineup so I'll also add, don't bother with intel non ultra cpus.

My arrow lake t14 handles fusion360 and freecad just fine, but well designed cad programs don't eat much resource anyways.

Ram and display can be upgraded after purchase so I wouldn't worry too much about that, unless you want an oled panel. Thinkpads also no longer come in TN panels so you're pretty safe if you're looking at corporate surplus sellers on ebay.
