The display panel model (Panasonic VVX17P051J00 / LEN4123) also has not changed; however, we have performed a subsequent analysis on its attributes thanks to possible differences in calibration or other parameters. The 17.3-inch anti-glare panel carries a 4K (3840x2160) resolution for a PPI of 255. Subjectively, it seems relatively rich in color and appears to carry good brightness and contrast values.

Measurements of 836:1 for contrast and 316.5 cd/m² for brightness reinforce our impressions. These values don’t deviate much from those of our previous measurements, which is expected. Brightness distribution of 86% again is practically unchanged, as is the black level of 0.397 cd/m² (which contributes to the good contrast values).

CalMAN 5 provides somewhat different measurements this time around, however, due to differences in calibration. DeltaE2000 values have dropped across the board, indicating greater color accuracy (ColorChecker DE2000: 3.15 vs. 3.8 on the previous P70; Grayscale DE2000: 3.72 vs. 6.09 previously). Total Gamma, on the other hand, is further from its ideal value of 2.2 (1.86 versus 2.3 previously). The same goes for CCT Average, which at 6103 indicates a warmer than ideal color temperature (6332 before). Color space measurements at least have not changed materially—we measured nearly identical values to our previous review in both AdobeRGB 1998 and sRGB comparisons (74.3% and 99.95%, respectively).

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
26.8 ms ... rise ↗ and fall ↘ combined ↗ 4 ms rise
↘ 22.8 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 51 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (26.3 ms).
       Response Time 50% Grey to 80% Grey
34.8 ms ... rise ↗ and fall ↘ combined ↗ 15.2 ms rise
↘ 19.6 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. » 24 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (42.1 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 detected 219.3 Hz ≤ 99 % brightness setting
 

The display backlight flickers at 219.3 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 99 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 219.3 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9953 (minimum: 43 - maximum: 588200) Hz was measured.

Outdoors, the panel is easy to read in the shade and is still functional in sunlight. Viewing angles are very good, as is always the case for IPS panels.

Performance

Apart from the significantly more powerful GPU and much faster NVMe solid-state drive, not much else has changed in terms of the internal specifications of the P70, either. The CPU has been swapped from the previous Intel Core i7-6820HQ for an Intel Xeon E3-1505M v5—not really an upgrade in terms of raw performance apart from the Xeon’s support for ECC memory and security management features. RAM capacity and speed remains the same at 16 GB of DDR4-2133 MHz, though now, the RAM is ECC (thanks to the upgrade to the Xeon CPU), which provides greater stability during intensive computational activities. The configuration is also single-channel (1x16 GB SODIMM) versus the previous dual-channel setup. This actually means slower memory performance unless a second 16 GB DDR4 stick is added aftermarket; however, on the bright side, the machine is ready and waiting for that upgrade—whereas the previous P70 would have required replacement of both SODIMMs to achieve the same performance at 32 GB capacity.

A couple more preliminary notes before we dive into performance analysis: LatencyMon provides no reason for concern as to the P70’s ability to stream real-time audio and video, and—as expected—performance suffers while operating unplugged (we measured 1394 in 3DMark Fire Strike Ultra versus 1927 while plugged in).

We will cover GPU and storage upgrades in later sections of this review, which is where most of the differences lie. For now, let’s take a closer look at the CPU and how it performs in comparison to its peers.

Processor

The Intel Xeon E3-1505M v5 is a high-end quad-core CPU designated for mobile workstations. Like the CPU in the previous P70 (Intel Core i7-6820HQ), it is a member of the Skylake series of CPUs, and it remains a quad-core processor. Clock rates are virtually identical (100 MHz higher, to be exact) at 2.8 – 3.7 GHz single-core and 3.3 GHz quad-core. We should expect few if any major performance deviations from the i7.

Since the Xeon supports ECC memory for greater system stability, the RAM (as previously mentioned) has been swapped for 16 GB ECC memory to take advantage of this capability. Apart from that, no major differences exist versus the Core i7—and exploring performance differences is likely to be a matter of splitting hairs.

Our benchmarks provide few substantial deviances between the previous P70 (equipped with the i7) and the current one. For starters, performance in Cinebench R15 is strong enough, with scores of 149 and 725 (single and multi-threaded, respectively). These values are within a few percentage points (3-6% lower) than the highest scores posted by competing machines, both of which hail from the Dell Precision 7710. The older P70 in this test is either roughly on par or slightly behind today’s configuration. Mostly the same observations apply to the Cinebench R11.5 results, which present a slightly wider gap (up to 8% advantage for the Precision 7710 in single-core performance and 7% lower scores for the older P70 in multi-core) but which otherwise are no different.
