You don't need an i7. Almost always you don't. This has been true since there were i5 vs i7 laptops. There is no 2018 ThinkPad in the X/P/T series which can't be equipped with at least 16GB RAM. Only the slotless machines (X280,X1 Carbon Gen 6 and the X1 Yoga Gen 3) stop this low, everything else has at least one slot and then the world is your oyster: 32GB modules are finally available so 40GB (one slot+8GB soldered to MB on the T480s), 64GB (two slots, T480, P1, X1E), 128GB (four slots on the P52/P72) is possible. You need to specify other criteria. Answer from chx_ on reddit.com

Why P series? - Going from X/T to P
June 28, 2023 - This high-performing Notebook has been the pinnacle of the X-series with its selection of top-of-the-line Intel Core H CPUs and Nvidia GeForce graphics. Though it performed well, it was never intended to be a workstation, since all the hardware couldn’t get certified by the various independent software vendors like Autodesk, Adobe, Dassault and Siemens. Therefore, the market for this kind of product got increasingly smaller, as it’s brother, the ThinkPad P1 already fulfilled all the needs from the above-mentioned vendors.

r/thinkpad on Reddit: Choosing a Thinkpad -- T vs P series
July 19, 2021 -

I need buy a laptop for school in a design field and have decided on a Thinkpad, but am a bit confused on several points. I will be running intensive 3D modeling and rendering software including Rhino, Solidworks, and Keyshot, along with Adobe programs (mostly Photoshop and Indesign, I expect.) I have been looking at mobile workstations.

I was about to pull the trigger on a T15g that I decided on last night, but when I came back to the page today, a sale had ended and the price had gone from 1,800ish to 2,200ish. I really want to stay under 2k, so I am reconsidering.

My confusion mainly stems from the GPUs. I know I need a good dedicated graphics card for the work I'll be doing, but most of the GPUs in the Thinkpads don't show up on sites. For example, is a "GeForce RTX 2070 Super with Max-Q 8GB," substantially different than a "Quadro T500 4GB"? In what ways are they different? How much does this difference matter? I had been thinking that I definitely needed a 8GB GPU, but I'm not quite sure about that any more.

At first, I was set on UHD, but is it that noticeably better than FHD? How important is the greater resolution to design work?

I know I need i7 or greater and 16GB or more memory.

Any of these points that someone could speak to, I would appreciate. Thank you!

TL;DR: Getting totally bogged down in the specs looking at laptops. Particularly confused about GPUs -- how much dedicated memory is necessary for 3D software? Not sure how much screen resolution is noticeable/matters.

X1 is the flagship, it's not really the best unless your definition of best is "lightest and slimmest". T(s) is the premium line. Slimmer and lighter than the T series, but not as slim and light as the X1. P are the mobile workstations. Powerful CPU's, usually lots of ram, multiple drives, has options for discrete graphics. T are the mainline portables. If you say "business laptop", this is what you're talking about. X are the smaller more compact version of the T series. They're often less upgradable as a trade-off for their having the same components in a smaller chassis. L are the value entry commercial business systems. All the same desirable by IT department features as the T and Ts, but much cheaper. Obviously, achieves that with having cheaper build materials, less premium options. E are the small business systems. Not up to the same level of build quality as the others, but because they're also designed by a different team, will sometimes adopt new ideas faster, and often offer some features the others dont (only non-workstation ThinkPads to offer multiple SSD slots). As far as what's best, it's whatever meets your needs in your price range. For me, that's CURRENTLY the L series. Inexpensive comparatively, offers the CPU's in the AMD version I like most of those I've had. I actually really like the chassis despite the cheap materials. Offers larger batteries than the T series (same as the Ts at a massively lower price), and still offers the low-power 400-nit screen.

Whats the best thinkpad series? whats the difference between all of the series? Basically, it goes like this: E Series: entry level series, aimed at small businesses and students. L Series: also entry level, but positioned above the E Series. Both the E and L Series are designed by Lenovo in China. T Series: the premier ThinkPad series, has improved build quality and features when compared to the two previous product lines. The TXXs models are thinner and have better case materials. X Series: the premium ultra portable (thin and light) series, has better case materials than the T Series and comes with 13 inch screens. X1 Carbon: the flagship ultra portable line, has all the bells and whistles together with excellent build quality in the 14 inch form. The X1 Extreme was a version of the P1 workstation line but with commercial GPUs, this model was discontinued and merged with the standard P1. Z Series: the apparently discontinued Z Series was the AMD version of the X1 Carbon line, although more focused towards "creatives" and media consumption. P Series: Workstation/desktop replacement line, they're big, thick and heavy but feature the most powerful CPUs and GPUs available. The PXXv models are cut down versions of the standard P Series. The PXXs models are basically T Series laptops but with high voltage CPUs and enterprise GPUs available. P1: the X1 Carbon equivalent for the P Series but in the 16 inch (formerly 15.6) form factor, also available with both enterprise and commercial RTX GPUs. The ThinkPad Z16 was the AMD version. The T, X, P and its derivatives are designed by Lenovo's (formerly IBM) Yamato Labs in Japan.
