HP ProBook 645 G3 review

HP ProBook 645 G3 — mobility 95 at $182 with a performance index of 0: the starkest split in the batch

A 2016 business 14-inch at $182, below the $297 class median. AMD Pro A10-8730B APU. The registered strength is mobility at 95 against a 60 median (+58%, high tier, top quartile); the registered weakness is the performance index at 0 (−100%). The value verdict: worth the asking price.

A carry machine that cannot compute

This is the clearest mobility-versus-compute trade in the batch: one of the highest mobility scores registered anywhere in this catalog attached to one of the lowest performance scores. The Carrizo-era A10 was weak even in 2016; measured today it scores zero. What the platform achieved instead was efficiency — light weight and class-topping battery economics that still define the machine.

How to use that split

The honest use case is a carry-only companion: a machine whose job is to be present and light — note-taking, document reading, email on the move — while doing nothing demanding. The Pro badge adds manageability heritage; the 0 performance index removes every ambition beyond that. The overall USComp score of 8 quantifies the ceiling.

Price trajectory

From a $1,300 base, decay has run 7.22% per year to $182, with a projected $156 (−14%) ahead. For the narrow duty it fits, the price asks little.

Against its neighbors

Pricier: the ThinkPad L480 ($192) and ProBook 440 G3 ($192) — both conventional balanced machines. Cheaper: the ProBook 430 G6 ($162) and EliteBook Revolve 810 G2 ($162). The ten-dollar steps in this band separate the carry-specialist from ordinary office machines; the choice depends entirely on whether the split serves the buyer.

Bottom line

A specialist of extremes: top-of-catalog mobility bolted to a floor-tier compute platform. As a light carry companion at $182 it is coherent; as anyone's only machine it is a mistake.
