The Chromium development team announced via a policy document that support will be dropped for older x86 CPUs that do not meet a minimum of SSE3 (Supplemental Streaming SIMD Extensions 3) support, starting in Chrome 89, APA-Economics reports citing Tech Radar.
The expected impact on Chrome usage is expected to be extremely small, given that the affected devices will mostly be running pre-Intel Core 2 Duo processors. As most post-2005 processors support SSE3 already, hardware will need to be upwards of 15 years old to be affected by this change.
