The 235HX and 245HX both claim 27 TOPS — does one really beat the other for AI?

  There is no real winner, only a paper delta. Both parts share a 27 TOPS NPU, so the 0.2GHz base-clock gap never surfaces on always-on chores like meetings and captions, and even sustained core-driven inference ends up decided by chassis cooling rather than the silicon. Nothing in everyday AI use will tell the two apart.

  Between two laptops holding these chips, take the better-cooled one; with cooling tied, take the cheaper and skip paying for a model name. The real bottleneck is not the HX letters but dual-channel DDR5 — memory bandwidth caps small-model speed on a laptop first, so the budget goes further on RAM.
