Intel benefits from decades of being the preferred platform for people to optimize server software on. I would believe that they outperform Graviton on workloads that have done this (especially when they have optimized with AVX instructions), but tends to be near performance parity on other workloads.
Databases and ML likely are winners for intel due to this optimization, while stuff like nginx performs just fine on the ARM chips.
I don't have much data here that's public. That said, Intel's AVX instructions generally give big advantages to range scans and other analytical workloads (as well as ML inference), while they don't help much for transaction processing. It depends on the DB and the workload. I would expect transactional benchmarks to look good for Graviton.
