There's e.g. the SiFive P650[0], from 2021. SiFive does claim it does outperform Cortex-A77. Cortex-A77 isn't ARM's fastest anymore, but it was in 2019. Meaning SiFive was, in 2021, not even 2 years behind. If tracing back to prior generations, you'll see SiFive has been quickly closing the gap. To the point that it wouldn't surprise me if at the next iteration from both companies, SiFive and ARM highest performance cores were on par. What's even more amazing is that SiFive's cores are consistently smaller area and lower power to the ARM cores they have comparable performance to.
