One of the many advantages with the newly announced EPYC 4005 series for entry-level servers is support for DDR5-5600 ECC memory compared to the current Xeon 6300 series being limited to DDR5-4800 memory. With the launch-day EPYC 4005 "Grado" benchmarks earlier this month of the AMD EPYC 4585PX and EPYC 4565P I was running with DDR5-5600 ECC memory modules. But for those wondering about the performance when using DDR5-4800 comparable to the Xeon 6300 / Xeon E-2400 series, here are some comparison benchmarks for reference.

S pomocí vývojových nástrojů z minulého dílu můžeme naplno začít programovat svůj počítač MB50. Napíšeme první jednoduchý program, systémovou knihovnu a několik demonstračních programů.

Dnes si představíme knihovnu nazvanou PeachPy, která umožňuje realizovat kooperaci mezi skripty v Pythonu a strojovým kódem zapsaným formou strojových instrukcí. PeachPy je v praxi relativně často používána pro „místní“ optimalizace.
