Recent benchmark data offers an in-depth look at the performance distinctions between two configurations of the Dell XPS 14 laptop. This analysis focuses on the Core Ultra 7 355 variant featuring Intel Graphics 4 Xe3 and its counterpart, the Core Ultra X7 358H equipped with the more powerful Arc B390 Panther Lake iGPU. Testing across various demanding scenarios, all conducted with an external monitor, reveals clear performance differentials in CPU, GPU, and power efficiency metrics.
Dell XPS 14 CPU Performance Benchmarks
The computational prowess of both Dell XPS 14 models was rigorously evaluated through industry-standard CPU stress tests. Under the demanding Prime95 V2810 Stress benchmark, the Core Ultra 7 355 with Intel Graphics 4 Xe3 registered an average output of Ø49.8 (ranging from 41.3 to 79.3). In contrast, the Core Ultra X7 358H model, utilizing the Arc B390 Panther Lake iGPU, achieved a notably higher average of Ø56.8, with scores fluctuating between 46.6 and 99.1 during the same test.
Further insights into multi-core processing capabilities were gleaned from Cinebench assessments. The Cinebench R15 Multi test saw the Core Ultra 7 355 configuration score an average of Ø59.6 (52.6-67.8), while the Core Ultra X7 358H variant significantly outperformed it with an average of Ø93.9 (89.5-96.9). Similarly, in the more extensive Cinebench R23 Multi benchmark, the Core Ultra 7 355 achieved an average of Ø56.6 (53.2-71.3), whereas the Core Ultra X7 358H maintained its lead with an average of Ø71 (41.1-94.8).
Integrated Graphics Performance: Dell XPS 14 GPU Stress Tests
The graphical performance of the Dell XPS 14 configurations was put to the test using both synthetic benchmarks and real-world gaming scenarios. The 1280x720 FurMark 1.19 GPU Stress Test revealed a distinct advantage for the Arc-powered model. The Core Ultra 7 355 with Intel Graphics 4 Xe3 recorded an average of Ø45.7 (43.5-56) during this intensive GPU load.
The Core Ultra X7 358H with its Arc B390 Panther Lake iGPU demonstrated superior graphical processing, achieving an average of Ø58.2 (42.2-74.1) in the identical FurMark test. This performance gap extended to gaming, with Cyberpunk 2077 FHD ultra no FSR yielding an average of Ø47.7 (44-57.2) on the Core Ultra 7 355 setup. The Core Ultra X7 358H delivered a slightly improved gaming experience, averaging Ø51.2 (30.8-56.9) in the same demanding title.
Dell XPS 14 Power Efficiency and Idle Consumption
Beyond raw performance, power efficiency is a crucial factor for portable devices. During an Idle 1min period, with an external monitor connected, the Dell XPS 14 featuring the Core Ultra 7 355 and Intel Graphics 4 Xe3 demonstrated remarkably low power consumption, averaging Ø1.763 (0.01133-5.61).
The Core Ultra X7 358H model, equipped with the more robust Arc B390 Panther Lake iGPU, exhibited a higher idle power draw. In the same 1-minute idle test, this configuration averaged Ø3.43 (1.646-5.16). These figures highlight a trade-off, where the enhanced processing and graphical capabilities of the Core Ultra X7 358H variant come with a slightly increased power footprint even during periods of minimal activity.
