ThinkPad P series

The ThinkPad P series line of workstation laptops produced by Lenovo and was introduced by the company as a successor to the previous ThinkPad W series. With 15.6" and 17.3" (later 16" only) screens, the ThinkPad P series saw the reintroduction of physically large laptops into the ThinkPad line. Marketed largely as portable workstations, many P series laptops can be configured with high-end mobile workstation-class Intel processors as well as error correction code (ECC) memory (only with Xeon and select Core HX processors) and a discrete Nvidia Quadro GPU. The P series offers independent software vendor (ISV) certifications from software vendors such as Adobe and Autodesk for various computer-aided design (CAD) software.

All 16" models have a standard 6-row ThinkPad Precision Keyboard (with Numeric Keypad and optional backlight), TrackPoint and touchpad, and optional fingerprint reader. In 2022, the 15.6" and 17.3" configurations have been dropped in favor of a 16" one, with the Core HX series, which replaced the mobile Xeon W line.

First generation
The first generation was announced at Autodesk University 2015 alongside the ThinkStation P310. It comes with a variety of "high-end" options such as Intel Xeon E3-1500M v5 processors, 4K IPS screens and DDR4 ECC RAM up to 64 GB. 1080p screens and 6th generation Core CPUs come standard along with PCI Express SSDs. The P series introduced a cooling system known as FLEX (Full Load Experience) that features two fans connected by a heat pipe and located near the CPU and GPU. A three-button touchpad is included.

P40 Yoga
P40 Yoga is a version of the ThinkPad Yoga 460 with Nvidia Quadro graphics.

P50s
ThinkPad P50s is an update of ThinkPad W550s, focused on mobility. Its chassis is based on that of the T560.

P50
The ThinkPad P50, while having a 15-inch display, shared little in design with the W541 which it replaced. Its ports had been re-arranged, it was slightly thinner than its predecessor, and it reintroduced indicator lights for hard drive activity. It supports up to three internal storage devices and has a single USB Type-C Thunderbolt 3 port while also featuring Mini DisplayPort and HDMI connections. Weighing 2.5 kilograms and having thickness of 2.6 centimeters, the P50 was lighter than previous W series laptops.

P70
The ThinkPad P70 marks the return of 17.3" option in the ThinkPad line. It has up to a Xeon E3-1500M series CPU, an Nvidia Quadro GPU, weighs 3.4 kilograms and is 3.1 centimeters thick. It supports up to four internal storage devices and includes two USB Type-C Thunderbolt 3 ports.

P51
A minor update to the P50, which included the updated CM238 chipset and either 7th generation Kaby Lake-H Core i7 processors or Xeon E3-1500M v6 processors.

P51s
The P51s chassis was based on the T570's. The CPU and integrated chipset was updated to Kaby Lake-U.

P71
A minor update to the P70, which included the updated CM238 chipset and either 7th generation Kaby Lake-H Core i7 processors or Xeon E3-1500M v6 processors, as well as Pascal-based Quadro GPUs.

P1 1st Gen
The ThinkPad P1 was based on the first generation of ThinkPad X1 Extreme. It features Intel Xeon E-2100M CPUs and Nvidia Quadro graphics.

P52
The P52 was a redesign of the P51, which introduced Coffee Lake-H Core i7 CPUs, all with 6 cores and 12 threads, the CM246 chipset, and Nvidia Quadro Pascal-based GPUs. It removed the mechanical docking port and ExpressCard slot, and features a narrower keyboard which is present on other ThinkPads.

P52s
Based on the ThinkPad T580, the P52s features a camera shutter, lateral instead of bottom-mounted docking port, and 8th Gen Core i5/i7 low power CPUs. The P52s includes quad-core Kaby Lake-R 15 W CPUs and Nvidia Quadro P500 GPUs.

P72
The P72 was a redesign of the P71, with features similar to those of the P52. It also features the narrower keyboard of the P52, and is the first 17.3" ThinkPad with a soldered GPU.

P1 Gen 2
The P1 Gen 2 was an update to the P1 which features Intel 9th Gen Coffee Lake-H Refresh Core i5/i7/i9 and Xeon E-2200M mobile processors and Nvidia Quadro Turinf-based series GPUs.

P43s
Based in the ThinPad T490, the ThinkPad P43s has a 14 inch screen. It features Intel 8th Gen Coffee Lake U-series processors and Nvidia Quadro Pascal-based graphics.

P53
A redesign of the P52, the P53 features a 4K UHD OLED Touch display, Wi-Fi 6, Intel 9th Gen Coffee Lake Refresh Core i5/i7/i9 and Xeon E-2200M mobile processors and Nvidia Quadro RTX Turing-based GPUs.

P53s
The P53s is an update to the P52s, which features Intel 8th Gen Coffee Lake U-series Processors, Nvidia Quadro P520 Graphics and up to 4K UHD (3840 x 2160) display, available with Dolby Vision high dynamic range (HDR) technology.

P73
The P73 was a redesign of the P72, with hardware upgrades similar to those of the P53. The P73 features new Intel 9th Gen Coffee Lake Refresh CPUs and Nvidia Quadro RTX Turing GPUs.

P1 Gen 3
Features Nvidia graphics and OLED screen.

P15v Gen 1
Based on the ThinkPad T15p Gen 1.

P14s Gen 2 (Intel or AMD)
The second generation P14s is just an iterative update of the previous model with new AMD Ryzen PRO 5xxx series and Intel 11th gen CPUs. The main difference between the Intel and AMD version is the Thunderbolt with USB 3.1 Gen 1 capabilities of the USB-C ports, which (including the USB-A) are USB 3.2 Gen 2 (no TB) on the AMD model, but also support DisplayPort alternate mode. The AMD and Intel model now also offer the same display panel options, while the aluminium case option is still exclusive to the Intel variant.

P1 Gen 4
Like on the ThinkPad X1 Extreme Gen 4, the 15.6" 16:9 IPS/OLED screen has been replaced by a 16" 16:10 one.

P1 Gen 5
Features NFC, liquid metal thermal paste, and 16:10 IPS screen options.

P16 Gen 1
Replaces both P15 & P17 line models with a single 16:10, 16" screen size in 3 resolutions & a non-touch/multi-touch option for the UHD.

P16s Gen 1 (Intel or AMD)
Replaces the P15s line with a 16" screen.

2024
On April 23, 2024, Lenovo announced four P series laptops. The ThinkPad P1 Gen 7 is the first computer, and laptop, using CAMM2 memory modules.
