https://ieeexplore.ieee.org/document/6877452 https://ieeexplore.ieee.org/document/6877452 describes a speedup of 41% when using TSX under a specific HPC workload.
https://www.phoronix.com/scan.php?page=news_item&px=RPCS3-Intel-TSX-Support https://www.phoronix.com/scan.php?page=news_item&px=RPCS3-In... describes a 40% speedup for an emulation workload with TSX.
Do we know what the slowdown will be for current gen CPUs for various workloads?
- bonzini 7y agoAs far as I know the only software that really wants it is SAP HANA. The slowdown should be small, that 40% speedup on emulation is specifically on load-locked/store-conditional instructions, and the linked blog post says "non-TSX CPUs such as Ryzen [had] a noticeable improvement in performance, although not to the same extent".
