SoCs, die auf dem neuen Kern basieren, sind haupts\u00e4chlich f\u00fcr Serversysteme und Workstations ausgelegt, es ist jedoch auch die Erstellung von abgespeckten Varianten f\u00fcr mobile und eingebettete Ger\u00e4te m\u00f6glich.    <\/p>\n<p>Im Vergleich zu P550 verf\u00fcgt der neue CPU-Kern von SiFive \u00fcber 16 MB L3-Cache statt 4 MB, kann bis zu 16 Kerne in einem Chip anstelle von 4 vereinen, arbeitet mit Taktraten von bis zu 3,5 GHz statt 2,4 GHz, unterst\u00fctzt DDR5-Speicher und PCI-Express 5.0. Die Gesamtarchitektur des neuen Kerns ist der von P550 \u00e4hnlich und ebenfalls modular aufgebaut, sodass zus\u00e4tzliche Bl\u00f6cke mit speziellen Beschleunigern oder GPUs in das SoC integriert werden k\u00f6nnen.
