We run the Cinebench R15 multi-core test in a loop and log temperatures, clock rates, power consumption etc. via HWinfo. Microsoft clearly offers the highest performance: The Surface Pro 6 starts at 638 points and then drops by 11% after the fifth round. It then remains at around 565 points. Lenovo's competitor starts with a higher score, but its performance drops by 32% in the second round and then remains at 420 points, which is 26% lower than the Microsoft's performance. But remember this is continuous load we are talking about.

HP does not fare much better. Its first-round results cannot even reach the Microsoft's performance during continuous load. Therefore, it does not have a lot to lose and we measured -16% overall. This positions the HP 22% behind the Microsoft during continuous load. We have included the results of the various i5 versions, including that of the Latitude 5290. You can see that the difference between the i5 and the i7 is only minimal during the Cinebench R15 loop. Only the Microsoft tablet offers a noticeable difference between the i5 and i7 versions. This is due to the different cooling systems. While the i5 version uses passive cooling (no noise), the i7 version has a fan.
