Does a hexa-core U-series processor under a 15 W power envelope make sense? As anticipated, Turbo Boost performance is excellent during the first few minutes before clock rates inevitably fall over time. The dip in performance comes out to be about 15 to 25 percent on the Dell XPS 13 7390 Core i7-10710U unit.

Back in August, we previewed a pre-production Core i7-10510U Comet Lake-U laptop courtesy of Schenker Technologies. Raw performance was somewhat disappointing at just a few percentage points over the Core i7-8565U at best even after tweaking its TDP levels to squeeze out as much as we could. Now that it's November, we can finally find proper Core i7-10710U laptops on store shelves with finalized drivers designed for consumers.

Our benchmarks below were performed on a retail Dell XPS 13 7390 which happens to be one of the first laptops to ship with the hexa-core Core i7-10710U. Unlike our early Schenker unit, these results should be a better representation of what consumers will see. Raw multi-thread performance is about 50 percent and 30 percent faster than the quad-core Core i7-8565U and more demanding 35 W Ryzen 7 3750H, respectively, according to CineBench R20. The deltas are generally smaller in other benchmarks like wPrime and HWBOT, but the advantage is still there in favor of the Comet Lake-U CPU. If you intend to run applications that can exploit 6 physical cores, then the hexa-core Core i7-10710U will benefit you the most.

As with most laptops running on ULV processors, however, the true story doesn't unravel until the CPU is subjected to prolonged stress in order to identify for any throttling behavior. When running CineBench R15 Multi-Thread in a loop on the XPS 13 7390, its Core i7-10710U CPU starts out strong at 1062 points before trending downwards as our graph above illustrates. A closer look at its clock rates and temperatures show a peak of 3.1 GHz and 97 C, respectively, during the first few minutes of the loop test. Thereafter, the CPU begins cycling between 1.7 GHz to 2.5 GHz and 64 C to 80 C. This roller-coaster-like behavior explains the shape of our CineBench loop test curve as well. Thus, while the Core i7-10710U sprints quickly out of the gate, it eventually slows and averages out to be just 8 to 10 percent faster than the Ryzen 7 3750H in raw multi-threaded performance. The AMD processor is better at maintaining consistent clock rates and thus more reliable performance over time when compared to Comet Lake-U.

Of course, other laptop manufacturers may implement the Core i7-10710U differently than Dell for potentially faster or slower performance results than what we've recorded here. We'll be reviewing more retail Comet Lake-U laptops in the coming months to paint a bigger picture of what Intel's first 15 W hexa-core U series CPU can offer.

After graduating with a B.S. in environmental hydrodynamics from the University of California, I studied reactor physics to become licensed by the U.S. NRC to operate nuclear reactors. There's a striking level of appreciation you gain for everyday consumer electronics after working with modern nuclear reactivity systems astonishingly powered by computers from the 80s. When I'm not managing day-to-day activities and US review articles on Notebookcheck, you can catch me following the eSports scene and the latest gaming news.
