SLOW Dell XPS 13 i3 CPU performance [FIXED!]
UPDATE: The latest Dell XPS 13 BIOS version A04 fixed the processor speed issue on my XPS 13, and it no longer requires SpeedStep to be disabled! You can find the download link here: Dell BIOS DL ORIGINAL POST: MARCH 5TH 2015 I recently purchased a new 2015 Dell XPS 13 “Infinity Display” laptop. Dell has been running some coupon specials and last week you could get the model with an Intel Core i3 processor for right around $700 USD.
