Nearly six months after the release of the Pixel 5, Google has revamped the way the GPU works, bringing the phone up to the level you'd expect from a Snapdragon 765G phone. The April 2021 security update for the Pixel 5 and Pixel 4a (5G) came with a note saying that it includes "performance optimizations for certain graphics-intensive apps & games." Hands-on testing reveals the update apparently dramatically improves the Pixel 5 GPU, reportedly showing performance gains of up to 50 percent in some apps and benchmarks.

We don't have a Pixel 5 on hand to test, but Andreas Proschofsky from Der Standard tipped off the Internet that he's seeing "30-50 percent better" performance in 3DMark after the update. Andrei Frumusanu from Anandtech confirmed "performance has been essentially doubled from the scores published [in Anandtech's review], and in line or better than other 765G phones," adding that "the fact it took 6 months is sad, though." Hmm. Yes.
