Lenovo ThinkPad P1 (Xeon E-2176M, Quadro P2000 Max-Q) Workstation Review

Extremely... professional? Today, we turn our sights to the workstation sibling of the critically acclaimed ThinkPad X1 Extreme. Our decked-out $4,220 configuration features a Xeon E-2176M CPU, Quadro P2000 Max-Q GPU, 2 TB NVMe SSD, and 32 GB of RAM. How does it handle our comprehensive array of tests?

Not to be outdone by the impressive ThinkPad X1 Extreme we reviewed last month is the state-of-the-art laptop’s business workstation counterpart, the ThinkPad P1. In terms of design and appearance, the machines are identical, but several critical parts have been swapped out for workstation-grade components in the P1. Namely, in place of the Core i7 CPU and NVIDIA GeForce GTX 1050 Ti Max-Q GPU, today’s P1 review unit features a Xeon E-2176M and Quadro P2000 Max-Q respectively. We were also pleased to find an absolutely massive 2 TB Samsung NVMe SSD in today’s machine—double the previous storage—and the same 32 GB of RAM and 4K HDR touch display. The towering price consequently dwarfs even that of the X1 Extreme: a mind-boggling $4220 as of this writing.

Our criticisms of the X1 Extreme were relatively minor indeed. Mostly, we regretted the glossy screen finish, overactive fans, high power consumption, and CPU performance on battery. By and large, the rest of our findings were overwhelmingly positive: terrific build quality and input devices, strong performance, a high-quality display, and good port selection and maintainability/upgradeability. How will today’s workstation counterpart measure up to the lofty standards set by its mass-market sibling?

Case

As previously mentioned, the ThinkPad P1 is identical in terms of case design and aesthetics, and the similarities also extend to the input devices and port selection. The only major differences in today’s review unit are the discrepancies in internal components we mentioned previously. As such, our evaluation of the physical aspects of the machine have not changed much since our X1 Extreme review.

To briefly summarize, the case is constructed purely from aluminum alloy, apart from the CFRP/GFRP hybrid display lid, which in our previous unit exhibited some creaking when pressure was applied from the rear. Today’s review unit seems better in this regard, though pressure in the upper-left corner did elicit a single “pop” when we first attempted it. Overall, the case quality is very good, up to the standards of recent ThinkPad machines.

Port selection is quite good, with a comfortable mixture of old and modern ports and good organization. Card reader and networking test results are strong, though the WWAN slot is conspicuously absent. Security options such as TPM 2.0, a touch fingerprint scanner, and Kensington Lock port are all present (though our display SKU lacks the ThinkShutter webcam cover). Finally, maintenance is a cinch, with all FRUs accessible beneath the bottom cover, which is easily removed with a Phillips-head screwdriver.

Display

The display panel in our ThinkPad P1 is also identical to that of our X1 Extreme review unit, so not much should have changed in this section either. Nevertheless, we’ll briefly cover our measurements of the P1’s screen, which (at least subjectively) does immediately make a good impression, with deep color saturation and what appears to be a good brightness and contrast. We note conspicuous backlight bleed in the upper corners and lower right of our review unit display.

* ... smaller is better

Resolution remains 4K/UHD (3840x2160), and the display still unfortunately features a glossy finish, which makes usage in brighter environments a bit of a challenge. It is fortunately quite bright, however, at 395.8 cd/m² average brightness (421.7 cd/m², with a brightness distribution of 85%). A black value measurement of 0.25 cd/m² yields the contrast ratio of 1590:1, which is good. The panel is designed for HDR capability, though its brightness falls far short of what would actually qualify it as an effective display in that regard.

In terms of color coverage, our measurements are identical with those of the X1 Extreme, at 87.6 percent of AdobeRGB and 100 percent of sRGB. This tops the results from both the Precision 5530 and HP EliteBook 1050 G1 by a notable margin (some 20 to 26 percent difference of AdobeRGB). Please note that the results appear different from the X1 simply because we measured against sRGB with the P1 rather than AdobeRGB; they are, in fact, the same panel. The default color profile was used.

CalMAN measurements have fluctuated somewhat since the X1 Extreme values were recorded, but an average ColorChecker DeltaE of 4.95 and Greyscale DeltaE of 5.1 are still good results. The CCT Average (7543) and Gamma (2.234) are also very close to the previous results.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
30.8 ms ... rise ↗ and fall ↘ combined↗ 16.4 ms rise
↘ 14.4 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 78 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.6 ms).
       Response Time 50% Grey to 80% Grey
55.6 ms ... rise ↗ and fall ↘ combined↗ 38 ms rise
↘ 37.6 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 91 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (41 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8929 (minimum: 43 - maximum: 142900) Hz was measured.

Outdoors, the P1 struggles thanks to its glossy display finish. The panel is bright, but the other competitors are brighter still. Viewing angles are excellent however.

Performance

While the ThinkPad P1 may be nearly identical to the X1 Extreme in most ways, it’s the internal components—CPU and GPU specifically—which differ from that of the X1 SKUs. For starters, although 8th-generation Core i5 and i7 CPUs are an option, there’s also the Xeon E-2176M, a true workstation-class processor. Similarly, rather than rely on conventional gaming GPUs from the NVIDIA GeForce lineup, the P1 offers either the NVIDIA Quadro P1000 or P2000 Max-Q to accommodate professional applications. RAM and storage range up to 64 GB and 2x 2 TB, respectively, with storage fully solid-state.

Our review unit is decked out with a Xeon E-2176M CPU, Quadro P2000 Max-Q GPU, 32 GB RAM (single DIMM), and a 2 TB NVMe SSD. Let’s see how it handles our bevy of performance tests.

Operating unplugged, the 3DMark 11 performance score drops to just 6292. We do not detect any DPC Latencies.

Processor

The Intel Xeon E-2176M is a hexacore CPU manufactured using Intel’s 14nm++ process and carrying a clock rate ranging between 2.7 and 4.4 GHz (4.1 GHz with all 6 cores active—vs 3.9 GHz on the i7-8750H). Up to twelve concurrent processing threads are possible via its support for Hyper-Threading. As compared with the Core i7-8750H, its clock rate is 300 MHz higher at turbo (500 MHz higher at base frequency), and it features a higher L3 cache of 12 MB (vs. 9 MB). It also supports ECC memory, though the RAM in our test unit is conventional. Both CPUs carry a TDP of 45 Watts.

How does the CPU perform, though, in our array of tests? Thanks to its higher clock rates, in single-threaded operations, it tops the charts: 187 points in Cinebench R15 1-CPU (2 points behind the Precision 5530) and 2.12 points in Cinebench R11.5 1-CPU, some 6% above i7-8750H-equipped machines (such as the X1 Extreme). However, in multi-threaded benchmarks, the differences evaporate, with a score of 1118 points in Cinebench R15 x-CPU (vs. 1135 in our original tests of the X1 Extreme) and 12.29 points in the respective test within Cinebench R11.5. In the case of our X1 Extreme, undervolting the CPU actually resulted in superior performance by around 8% in the Cinebench R15 test, so there’s reason to believe similar results could be achieved with the P1 with the same strategy.

Without any CPU voltage adjustments in play, the ThinkPad P1 starts with a score of 1121 in our Cinebench R15 multi-CPU loop test before dropping into the 1015 – 1030 range for subsequent runs. The stock X1 Extreme (powered by its Core i7-8750H) has a marginal advantage here, as we noted earlier; it begins with a score of 1127 and then drops (runs 2 - ∞) into the 1050 – 1070 range. Apart from the MacBook Pro 15, which performs marginally better than the P1 in the sustained performance test, the P1 is in line with the rest of the competition here. Such a result doesn’t inspire a great amount of confidence in the actual performance premiums one might hope to expect from the pricier Xeon CPU. As far as our tests are concerned, it seems that the Xeon P1 actually loses out to i7-equipped machines in multi-core performance but manages superior results in single-core tests. Naturally, the fact that ECC RAM is also supported may prove to be of greater interest to companies indulging in professional CAD software and the like.

Speaking of which, the only machine we’ve reviewed that shares the P1’s Xeon E-2176M CPU is the Dell Precision 5530 (back in August), and in multi-core performance, the P1 edges out the Precision by a couple of percentage points on average. The two machines are more closely-matched in single-core tests, but across the board, the P1 still fares better here.

System Performance

Subjectively, system performance is never a problem with the P1: we haven’t experienced any hiccups, hangs, or other concerns during our time with the test unit. Synthetically, the PCMark scores (such as the 4618 we received in PCMark 10) are actually a few percentage points below those we recorded from the X1 Extreme (and some 7 to 11 percent below the Precision 5530), but such discrepancies aren’t obvious during daily use, and their origins are not clear. As we often point out, suffice it to say that all of the machines in today’s comparison field in this section feel fast enough such that any small differences in synthetic performance results are not likely to bare themselves out in tangible form.

Storage Devices

Storage performance is also not a concern on the ThinkPad P1. Our test unit arrived with a massive 2 TB Samsung PM981 NVMe SSD installed—a very expensive, and uncommon, piece of hardware indeed. With 4K-64 Read/Write speeds of 1449.63 / 1866.41 MB/s, however, as well as an overall AS SSD Score of 4784, if you’re looking for capacity and speed, this drive is quite clearly a good choice.

What’s more, the P1 actually provides two separate M.2 NVMe (PCIe-x4) slots, one of which is unpopulated in our review unit. That means that hypothetically the user could add a second 2 TB SSD, bringing the total capacity to 4 TB. Or, alternatively, the drives can be configured in RAID-0 for performance or RAID-1 for data redundancy. Again, upgrades and maintenance are a cinch on the ThinkPad P1, so this wouldn’t be too much trouble to implement as an aftermarket solution.

There is no conventional 2.5-inch drive bay within the P1, which isn’t surprising given the trends of the industry.

GPU/Workstation Performance

Another of the major differences between the X1 Extreme and the P1 is the GPU selection. Whereas the X1 Extreme is powered by a GeForce GTX 1050 Ti Max-Q, the ThinkPad P1 offers two GPU options, and both are workstation-class: the Quadro P1000 Max-Q and P2000 Max-Q. The differences in performance between these two options are notable; the P2000 alone is some 25 to 30 percent faster in our benchmarks, and since the GPU can’t be upgraded aftermarket, it’s important to opt for the one that fits your needs from the outset. It’ll be interesting to see how well the Max-Q variant of the P2000, which is likely to perform closer to the P1000, handles our testing today.

NVIDIA Quadro GPUs are professional graphics adapters and as such are not optimized for gaming (or gaming benchmarks) as are the GeForce GTX series GPUs. The X1 Extreme posts scores about 6 to 10 percent higher than the P1 in our 3DMark benchmarks.
