MagyarDell XPS 13 7390 Core i7-10710U Laptop Review: Faster Than The Core i5 XPS 15
After a short delay, the Dell XPS 13 7390 clamshell with Intel's latest 10th gen Core i7-10710U processor has finally begun shipping. Dell was first out of the gate with an Intel Core i7 Ice Lake offering earlier last month and now it is first again with with Intel's Core i7 Comet Lake-U CPU. This particular processor is notable for being the first hexa-core CPU in the 15 W Core U series whereas all previous Core U CPUs had a maximum of just two or four physical cores.
Other than the CPU swap, the chassis here remains identical to the XPS 13 models that have come before it. The change in model name (7390 vs. 9390) was also announced earlier this year as detailed here. We therefore recommend checking out our existing reviews on the XPS 13 9380 and XPS 13 9370 to learn more about the keyboard, display, ports, and other physical features of the XPS 13. This review will instead focus on the new Core i7-10710U and how much of a performance boost users can expect.

Communication
Display
Dell has equipped our Comet Lake-U unit with the same 4K UHD AU Optronics B133ZAN IPS panel as found on the XPS 13 9380 series. Thus, innate characteristics like color coverage, response times, and contrast ratios are almost the same between them.
Uneven backlight bleeding, however, is slightly worse this time around. Our picture shows moderate bleeding from the corners of the screen that becomes noticeable when viewing videos with black borders.
Maximum brightness drops to about 300 nits from 400 nits when disconnected from an outlet. Unlike on most other laptops, this power-saving behavior can only be toggled via the XPS 13 BIOS.

Performance
Much like the jump from dual-core Kaby Lake to quad-core Kaby Lake-R, the hexa-core Comet Lake-U adds two more physical cores for a total of 12 threads under the same 15 W to 25 W power envelope. Intel has even managed to up the single-core Turbo Boost frequency every-so-slightly from 4.6 GHz on the Core i7-8565U to 4.7 GHz on the Core i7-10710U. Note that only the Core i7 SKU is hexa-core as the lesser Core i5-10210U Comet Lake-U option is quad-core.
As expected, the XPS 13 still suffers from DPC latency issues just like many of its older siblings.
Processor
CPU performance is impressive at first glance because of the very fast but short-lived multi-core Turbo Boost potential of the hexa-core CPU. As illustrated by our graph below, running CineBench R15 Multi-Thread in a loop results in high initial scores before performance eventually falters over time in order to keep thermals in check. While this behavior is normal for ULV CPUs, the extent to which this occurs is more extreme on the hexa-core XPS 13 7390. The highest and lowest scores recorded on our hexa-core unit, for example, came out to be 1062 points and 689 points, respectively, compared to 637 points and 581 points on the older XPS 13 9370 with the Core i7-8550U CPU. This means that the hexa-core XPS 13 7390 is at its best when short bursts of high CPU performance is desired.
See our dedicated pages on the Core i7-10710U for more technical information and benchmark comparisons.

System Performance
PCMark benchmarks rank our Comet Lake-U-powered XPS 13 7390 behind the Ice Lake-U-powered XPS 13 7390 2-in-1 despite the faster CPU performance of the former. It's likely that the significantly more powerful Iris Plus GPU of the Core i7-1065G7 was enough to propel the XPS 13 7390 2-in-1 over its clamshell sibling.
We experienced no software or hardware issues during our time with the unit. We recommend users become familiar with the Dell Power Manager app as key functions like power profiles, performance level, and battery health can all be accessed here.

Storage Devices
Dell sources their SSDs from multiple suppliers for all their laptops. We've personally tested XPS 13 units equipped with Samsung, Toshiba, or SK Hynix and so it's a safe bet that your next XPS purchase will house one of these three manufacturers. Our XPS 13 7390 uses the newer SK Hynix PC601 SSD in contrast to the SK Hynix PC401 on last year's XPS 13 9380.

The integrated UHD Graphics 620 has not changed from the previous generation. While Fire Strike and Time Spy Graphics scores are each 19 percent higher than the average UHD Graphics 620 in our database, that's not really saying much since this particular GPU is years old. You'll have to opt for an Ultrabook with the Core i7-1065G7, Ryzen 7 3700U, or GeForce MX150/MX250 if you want more GPU horsepower.

Emissions
System Noise
Nothing has changed about the cooling solution and so fan behavior is not unlike what we experienced on the XPS 13 9380. At worst, fan noise will be steady at about 31.1 to 33.7 dB(A) against a background of 28 dB(A) when video streaming or during heavy web browsing. Fan noise can be up to 46.5 dB(A) when the CPU is at 100 percent utilization.
We're able to notice slight coil whine or electronic noise when placing an ear on the keyboard keys.

Temperature
Surface temperatures are nearly identical to what we discovered on the XPS 13 9380 with the quad-core Whiskey Lake-U CPU. In other words, users are reaping the benefits of the Comet Lake-U CPU without any higher temperatures commonly associated with increased performance.
(±) The maximum temperature on the upper side is 44.6 °C / 112 F, compared to the average of 35.8 °C / 96 F, ranging from 21.4 to 59 °C for the class Subnotebook.
(-) The bottom heats up to a maximum of 49.2 °C / 121 F, compared to the average of 39.5 °C / 103 F
(+) In idle usage, the average temperature for the upper side is 26.6 °C / 80 F, compared to the device average of 30.7 °C / 87 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 31.4 °C / 88.5 F and are therefore cool to the touch.
(-) The average temperature of the palmrest area of similar devices was 28.3 °C / 82.9 F (-3.1 °C / -5.6 F).
Stress Test
We stress the system with synthetic loads in order to identify for any potential throttling or stability issues. When running Prime95, the CPU can be observed boosting up to 4 GHz for the first few seconds before falling and stabilizing at the 3.0 to 3.1 GHz range. Core temperature would also be stable at about 95 C during this period. After about 1.5 minutes, clock rates and temperature drop to cycle between 1.7 GHz to 2.5 GHz and 64 C to 80 C, respectively, since the CPU is unable to sustain consistent maximum Turbo Boost indefinitely as discovered during our CineBench R15 Multi-Thread loop test. Running both Prime95 and FurMark results in similar clock rate and temperature cycling behavior as shown by the screenshots and table below.
While most laptops with ULV CPUs experience performance dips when subjected to extreme stress, the wide-ranging cycling behavior as observed on this XPS 13 unit is uncommon. Dell's unique approach has its pros and cons; while the CPU can occasionally reach higher clock rates than usual when under stress, performance can also become inconsistent on a moment-to-moment basis.
Running on battery power will limit CPU performance. A Fire Strike run on batteries returns Physics and Graphics scores of 12325 and 1333 points, respectively, compared to 14847 and 1339 points when on mains.
| CPU Clock (GHz) | GPU Clock (MHz) | CPU Temperature (°C) | |
| System Idle | -- | -- | 35 |
| Prime95 Stress | 1.8 - 2.5 | -- | 64 - 80 |
| Prime95 + FurMark Stress | 0.8 - 1.1 | 650 - 850 | 60 - 66 |
Energy Management
Power Consumption
Average power consumption is very close to what we observed on both the last generation XPS 13 9380 and XPS 13 9370 each with 4K UHD panels. After all, they each ship with the same small (~6.0 x 5.5 x 2.3 cm) 45 W USB Type-C AC adapter that can also be used to recharge USB Type-C devices and compatible laptops with USB Type-C PD. Nonetheless, power consumption will cycle when under extreme processing stress as shown by our graphs below.

Battery Life
Perhaps as a direct consequence of having similar power consumption behavior as the older XPS 13 9380 and 9370 series, battery life on the new Comet Lake-U option is about the same as its older siblings. Users can expect just over 8 hours of real-world WLAN use before needing to recharge.

Verdict
Do you really need a hexa-core processor for a subnotebook? If your intention is to use for the XPS 13 mostly for web browsing, video streaming, word processing, or other light office tasks that the series was initially designed for, then the older quad-core Core i7-8565U will be enough. PCMark 10 scores are so close between the XPS 13 7390 and XPS 13 9380 that it becomes hard to justify the price premium for owning a hexa-core XPS 13 especially since most users won't feel the difference during day-to-day loads.
On the other hand, power users who want to exploit the two additional cores of Comet Lake-U will be happy to find that the raw multi-thread performance boost over Whiskey Lake-U is quite significant even after accounting for the unsteady cycling clock rates and limited maximum Turbo Boost sustainability. If you frequently run programs that can benefit from additional threads or want to connect eGPU docking stations to your XPS 13, then the hexa-core Core i7-10710U SKU would be worthwhile.
The hexa-core XPS 13 7390 is for power users who want the performance of a baseline Core i5 XPS 15 in a smaller 13.3-inch package. The system is able to offer increased performance without any noticeable drawbacks to battery life, surface temperatures, power consumption, or fan noise.
