[Hardware Unboxed] Intel Arc B580 overhead issue! Upgraders beware (youtu.be)

Fleshbag summary: Intel Arc seems to have significantly higher (driver?) overhead than Nvidia/AMD cards, causing lower-than-expected performance in situations where the system has a "weak-ish" CPU (e.g., i5 9600K / Ryzen 2600) and the game (and settings) are CPU-demanding. This also likely explains why original B580 reviews sometimes saw lower-than-expected performance drops in some titles when testing at 1440p vs 1080p.

The problem seems to be exasperated with Battlemage (Bxxx) compared to first gen Alchemist (Axxx), possibly due to higher raw performance.

(As per the video itself, HUB's coverage is building on an original investigation by Hardware Canucks.)
