Spotted at Extreme Tech is a report on the variation between processor speeds on Intel Core-M devices between OEMs (Original Equipment Manufacturers):
...users have generally been able to expect that a CPU in a Dell laptop will perform identically to that same CPU in an HP laptop. These assumptions aren’t trivial — they’re actually critical to reviewing hardware and to buying it.
The Core M offered OEMs more flexibility in building laptops than ever before, including the ability to detect the skin temperature of the SoC (System on Chip) and adjust performance accordingly. But those tradeoffs have created distinctly different performance profiles for devices that should be nearly identical to one another

Same memory. Same processor, but a lot more performance.
Just having Microsoft update under manual control helped a helluva lot.
Not to say what Norton, Symantec, and a few other vendors who slipped into the covers with HP were doing as well. One by one, I kept nixing them.
Cleaning out the autoruns [microsoft.com] and running only what I needed helped a *lot*!
