MagyarCore i7-1165G7 vs. Core i7-1185G7: Dell XPS 13 9310 4K Laptop Review
The Dell XPS 13 9310 launched just a couple of months ago alongside Intel's brand new 11th gen Tiger Lake-U platform. Based on our time with a unit, performance proved to be a noticeable upgrade from the XPS 13 9300 especially in terms of graphics even though there were no changes to the external design. If you owned an older XPS model or could use the graphics boost, then an upgrade to the XPS 13 9310 would make a lot of sense.
This time, Dell has sent us a higher-end second XPS 13 9310 unit equipped with the Core i7-1185G7 CPU and 4K UHD display in contrast to our first unit equipped with the Core i7-1165G7 and FHD display. The configuration currently retails for about $1600 USD or roughly $300 more than the Core i7-1165G7/FHD option. See our existing reviews on the XPS 13 9300 and XPS 13 9310 to learn more about the chassis and its features as our review here will focus on the differences between the Core i7-1165G7/FHD and Core i7-1185G7/4K XPS 13 9310 SKUs. Is the costlier option worth the extra Benjamins?

Display
Dell uses the same Sharp LQ134R1 IPS panel for its last generation XPS 13 9300 4K and current generation XPS 13 9310 4K for a similar gen-to-gen visual experience. A major difference we've noticed between our two units, however, relates to the brighter display on the newer XPS 13 9310 (479 nits vs 401 nits). Pulse-width modulation is also present on the newer model whereas it was absent on the older XPS 13 9300 4K to suggest that Dell may be using a different backlight this time around.
Brightness uniformity could be a bit better on our unit. The top left corner of our display is slightly dimmer than it should be as shown by our measurements below. It's not enough to be all that noticeable, but we do expect better from a flagship series like the XPS.

Color space covers all of sRGB and approximately 70 percent of AdobeRGB. There are no AMOLED or full AdobeRGB/DCI-P3 options likely because such panels are not widely available in the 16:10 13.4-inch screen size.
Color temperature is slightly too warm out of the box, but this is nothing our X-Rite colorimeter couldn't fix after a calibration (6245 to 6442 CCT). Average Color and grayscale DeltaE values would also improve just marginally after a bit of tweaking not unlike our experience with the XPS 13 9310 FHD or XPS 13 9300 4K configurations.

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 2137 Hz | ≤ 31 % brightness setting |  |
The display backlight flickers at 2137 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 31 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 2137 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 19035 (minimum: 5 - maximum: 3846000) Hz was measured. | |||
Outdoor visibility is not great if on a bright day due to the glossy panel. Unlike some older XPS 13 models, Dell offers no matte option for its XPS 13 9310 series. However, the display is generally bright enough for comfortable viewing if working under shade.
Performance
On paper, the Core i7-1185G7 has slightly faster base clock rates and Turbo Boost clock rates than the Core i7-1165G7 (3.0 to 4.8 GHz vs. 2.8 to 4.7 GHz). In practice, however, we're going to show that these printed specifications don't really mean much when both processors are at the mercy of the same chassis cooling solution. There are no other major differences between the two processors as their cache sizes, TDP range and core count are identical. GPU-Z reports some slight fillrate differences between the integrated Iris Xe GPU, but nothing significant.
We set our unit to Ultra Performance mode via the Dell Power Manager software prior to running any performance tests below for the best possible numbers. Owners should become familiar with this software since many XPS-specific options are found here.
Processor
Much like what we observed between the XPS 15 Core i7-8750H and XPS 15 Core i9-8950HK, performance differences between our XPS 13 Core i7-1185G7 and Core i7-1165G7 configurations are minimal at best. Benchmark results are almost identical between them to the point where the Core i7-1165G7 can sometimes even edge out ahead of the Core i7-1185G7 like in HWBOT x265 encoding. When running CineBench R15 xT in a loop, the same clock rate fluctuations occur for unsteady scores due to Dell's Dynamic Power Policy implementation.
It's too bad that the XPS 13 doesn't offer AMD Ryzen options as the Ryzen 5 4500U or Ryzen 7 4700U have even faster multi-thread performance than these Intel Tiger Lake CPUs albeit at the cost of slower single-thread performance.

GPU Performance
Strangely, 3DMark results are consistently higher than what we recorded on the XPS 13 Core i7-1165G7 even though games seem to run a bit faster on the latter configuration. Time Spy graphics, for example, is 30 percent higher for our XPS 13 Core i7-1185G7 SKU while frame rates when running games like DOTA 2, Final Fantasy XV, and GTA V are a few frames lower than on the XPS 13 Core i7-1165G7. We don't have a firm explanation on the discrepancies, but they do mean that users should expect about the same graphics performance as the XPS 13 Core i7-1165G7 in more real-world scenarios outside of 3DMark. We suspect that the fluctuating clock rates and differences in cold state prior to running the tests may have influenced the final scores.
Idling on Witcher 3 at low settings shows the same sinusoidal fluctuations in frame rates much like what we observed on the XPS 13 9310 Core i7-1165G7 and CineBench R15 xT loop test above. In this example, frame rates would cycle between 50 FPS and 90 FPS due to the cycling clock rates.
