Lenovo ThinkPad P53Source: Windows Central

The ThinkPad P50 series brings impressive performance and plenty of configuration options in a thick, durable chassis. The P53 is a continuation of the line — we previously reviewed the P52 — now with more powerful hardware than ever before as well as few other changes. I used the P53 for about a week to see what it's all about and whether or not it's worth the rather steep (but understandable) price.

Lenovo supplied Windows Central with a review unit of the ThinkPad P53 complete with Intel Xeon E-2276M vPro processor (CPU), 64GB of DDR4 RAM, a 1TB M.2 PCIe solid-state drive (SSD), and an NVIDIA RTX 5000 Max-Q dedicated graphics card (GPU) with 16GB of GDDR6 VRAM. Although it's not equipped with a comparatively high-end 4K OLED display — it's instead using an FHD panel with Dolby Vision HDR 400 and brightness up to about 500 nits — you're still looking at a price of more than $7,000 before any special discounts often offered by Lenovo.

This is a configuration that rivals desktop PCs in terms of performance, and there are far more affordable options available. Entry-level models start at about $1,489 before any coupons and include a 9th Gen Intel Core i5-9400H vPro CPU, 8GB of DDR4 RAM, 256GB PCIe SSD, and NVIDIA Quadro T1000 GPU with 4GB of VRAM.

Also available are 9th Gen Intel Core i7-9850H and Core i9-9980H CPUs, as well as NVIDIA T2000, RTX 3000, and RTX 4000 GPUs. Due to space constraints, the two lower-end GPUs can be had with two M.2 PCIe SSD slots and a 2.5-inch HDD slot, while the higher-end GPUs come with three M.2 PCIe SSD slots.

What I loved about the ThinkPad P53

The ThinkPad P53 hasn't changed much physically since the P52, and you can still expect a rather chunky laptop with enough space for the formidable hardware inside. It's about an inch thick and has a starting weight of 5.5 pounds, so you'll want a sturdy laptop bag if you plan on often carrying it around with you. Ports have been updated and moved around a bit, but you can still expect generous connectivity. On the left are HDMI, two USB-A, an SD card reader, and space for an optional Smart Card reader, while the right side includes a 3.5mm audio jack, USB-C, and space for a SIM slot if you check out with an LTE modem inside. The back edge is reserved for the ports you'll likely use the most in order to keep them out of the way. The proprietary Lenovo charging port is joined by two Thunderbolt 3 — ideal for connecting a powerful docking station — and RJ45 Ethernet.

The ThinkPad P53 pushes performance to impressive levels.

The bottom portion of the chassis is made of a magnesium-aluminum alloy, while the lid and palm rest are glass-fiber reinforced plastic. The usual black ThinkPad soft-touch finish is here, and as usual, it's a total fingerprint and smudge magnet; keep a cleaning cloth close if this sort of thing irks you. Even after scrubbing the lid with a cloth and cleaning solution, fingerprints are still evident. The P53 has undergone MIL-STD 810G durability testing to ensure it can put up with use and abuse above what you'd find in an office, so don't be scared to take it with you into the field. It's rigid and heavy enough that I'd be more afraid of it damaging whatever it fell on rather than taking damage itself.

You get a full keyboard with a number pad and three-stage backlight (off, bright, and brighter), as well as a TrackPoint system with red pointing nub in the middle. I don't still have a P52 to test key travel side-by-side, but it does seem like the P53's travel distance has been shaved down slightly. It's still plenty comfortable, and anyone who types a lot should be satisfied. The Precision touchpad tracks well and includes slim physical buttons below. Dual 2W speakers are positioned above the keyboard, and Dolby Atmos helps give them a rather full sound. They get loud without distorting, and I had no issues watching videos and listening to music. Below the keyboard is a fingerprint reader for added security.

The lid sits on two small hinges that allow it to be opened with one hand (weight plays a huge part here). The bezel is rather thick around the 15.6-inch display due to the overall size of the bottom portion of the laptop, but the P53 really isn't trying to win any style awards. Opting for the FHD display with Dolby Vision HDR 400 (which is what the review model uses) opens up the option to add an IR camera for facial recognition, and the standard 720p webcam includes a shutter for extra privacy. The non-touch display has a matte finish to help with working in well-lit areas and combined with about 500 nits brightness. It's more than enough to mostly eliminate glare. Testing color accuracy, I got back 99% sRGB, 76% AdobeRGB, and 70% NTSC. For those who need a more accurate color, there are also two 4K display options available. The LCD option manages 100% of the AdobeRGB color gamut and also includes Dolby Vision HDR, while the OLED 4K option hits 100% DCI-P3 color reproduction and includes touch function. 4K OLED is no doubt the best option, but it also raises the price by a few hundred dollars.

On the bottom of the P53 is a seven-screw panel that can be removed for quick access to internal hardware. There are, in total, four SODIMM RAM slots, with two easily accessible and two harder to reach between the keyboard and motherboard. The review unit, due to the beefy GPU, doesn't have room for a 2.5-inch HDD, so instead has three M.2 slots for SSDs. You should have no issue adding enough hardware to tackle most intensive tasks. The Intel Xeon CPU and NVIDIA Quadro RTX 5000 Max-Q GPU with a whopping 16GB of VRAM in the review unit are extremely powerful, but keep in mind the Max-Q designation means it's about 10-15% less powerful than a full desktop option. The P53 comes with a ton of Independent Software Vendor (ISV) certifications to ensure it will work with most programs in specialized fields.

The Samsung SSD in the P53 is extremely fast, and there are two easily-accessible M.2 slots sitting empty if you'd like to add storage.

Battery life depends on what you're using the laptop for, as well as what hardware is in use. For general productivity work, I saw between four and five hours with performance set to high. Tempering performance and lowering display brightness adds a couple of hours, and you might be able to push eight hours total without needing a charge. This is without a 4K display, which would sap battery life further. Like a gaming laptop, if the GPU is in full use, you won't want to be caught without the AC adapter; expect battery life to fall to less than two hours from a charge. The P53 does feature quick charge so that you can get about 80% battery life back in just less than an hour.

What I disliked about the ThinkPad P53

Other than the price and weight — both tradeoffs necessary for the level of performance available within — I noticed a couple of things about the P53 that might irk some people. First is the lack of modular battery, something the P52 offered. There was no built-in battery to make hot swaps possible on the older model, but you could still charge up a couple of batteries if you knew you were going to be away from a wall plug for an extended period of time. Third-party portable batteries have sort of killed the need for modular batteries on laptops, but it was still a nice feature.

Heat does accumulate despite ample venting on the bottom and sides of the laptop, and if you're working long hours with intensive programs, you're likely going to see some thermal throttling. Lenovo's Vantage app offers a custom performance tuning to prevent throttling, though you're not going to be able to hit the same performance with it enabled. I ran two sets of benchmarks — one with Lenovo handling performance and one with a custom high-performance setting — and found a noticeable difference between the results. You'll see improved performance without Lenovo's tuning, but only up to the point where things get too hot. The fans are quiet, though, so that's a plus.

I also noticed some coil whine when the laptop was under load, which I found is apparently a relatively common issue after poking around online. It's not a dealbreaker, but keep it in mind if it's something you can't live with. There was also the issue of having Wi-Fi drop about every 30 minutes with about a minute break until it reconnected. I was located almost directly next to my router, and my other devices didn't have the same problem. This no doubt won't be an issue for all models, and in any case, the wireless adapter is easy to swap out.

Should you buy the ThinkPad P53?

The ThinkPad P53 is undoubtedly a powerful mobile workstation, designed to fulfill the role of a full desktop PC for designers and developers. It's available with impressive performance hardware and a bunch of different display options, up to a 4K OLED touch option that I wish I was able to test. Battery life isn't all that great, especially when you're pushing power, but that's an understandable tradeoff.

4 out of 5

The P53 is durable, it can be upgraded easily thanks to a removable panel and lots of space for hardware, and it makes typing extremely comfortable. This isn't a laptop for everyone due to the size and hardware inside, but those who need it for specialized work will no doubt swallow the price and find that it's more than up to the task at hand.
