Dell XPS 15 9500 Core i7 GeForce GTX 1650 Ti Laptop Review: No Core i9 Nonsense

06

We stress the laptop to identify for any potential throttling or stability issues. When running Prime95, clock rates would boost up to 4.2 GHz for about 15 seconds until hitting a core temperature of 99 C. Thereafter, clock rates would fall to the 3.4 to 3.5 GHz range in order to maintain a slightly cooler core temperature of 90 C. After a minute, however, clock rates and temperature would fall even further to 2.9 GHz and 73 C, respectively, as shown by our screenshots below. This would occur even when running on Dell’s Ultra Performance mode. Keep in mind that the Core i7-10875H is rated for a maximum Turbo Boost clock rate of 4.3 GHz for all eight cores meaning that the steady-state 2.9 GHz Turbo Boost on the XPS 15 is likely thermally limited.

When running Witcher 3, both the CPU and GPU would each stabilize in the low 70 C range to be nearly identical to what we recorded on last year’s XPS 15 7590 with the Core i9 CPU and GTX 1650 GPU. From what we can tell, it looks like Dell was aiming to keep temperatures relatively consistent gen-to-gen meaning that users shouldn’t expect the XPS 15 9500 to run all that much cooler or warmer than previous generation models despite the significant chassis redesign.

Interestingly, GPU clock rates would alternative between ~1470 MHz and ~1650 MHz every few minutes when idling on Witcher 3 instead of remaining constant like on most other laptops. The cycling clock rates are likely responsible for the undesirable frame rate behavior mentioned in our Witcher 3 graph above.

Running on battery power will limit performance. A Fire Strike run on batteries returns Physics and Graphics scores of 17354 and 7956 points, respectively, compared to 21030 and 9930 points when on mains.
