64-bit Chrome offers many benefits for speed, stability and security. Our measurements have shown that the native 64-bit version of Chrome has improved speed on many of our graphics and media benchmarks. For example, the VP9 codec that’s used in High Definition YouTube videos shows a 15% improvement in decoding performance. Stability measurements from people opted into our Canary, Dev and Beta 64-bit channels confirm that 64-bit rendering engines are almost twice as stable as 32-bit engines when handling typical web content. Finally, on 64-bit, our defense in depth security mitigations such as Partition Alloc are able to far more effectively defend against vulnerabilities that rely on controlling the memory layout of objects.
