Google Cloud recently launched their N4A series powered by their in-house Axion ARM64 processors. In that launch-day benchmarking last month was looking at how the N4A with Axion compared to their prior-generation ARM64 VMs powered by Ampere Altra. There were dramatic generational gains, but how does the N4A stand up to the AMD EPYC and Intel Xeon instances? Here are some follow-up benchmarks I had done to explore the N4A performance against the Intel Xeon N4 and AMD EPYC N4D series.

Moderní překladače při zpracování hodnot s plovoucí řádovou čárkou dodržují normu IEEE 754, a to včetně rozšíření této normy (IEEE 754–2008). To sice zajišťuje stabilitu, ale někdy je vhodné se od této normy odklonit.
