But it turns out that not every laptop with a Thunderbolt 3 port can take full advantage. YouTuber Jarrod’sTech ran a series of tests and determined that a notebook with a 10th-gen Intel Comet Lake-H processor performs much more poorly when gaming with an external graphics card than a system with a 10th-gen Ice Lake chip, even though Ice Lake has lower power consumption.
