Kampani ya SiFive, yomwe idakhazikitsidwa ndi omwe amapanga mapangidwe a RISC-V komanso nthawi ina ikukonzekera purosesa yoyamba ya RISC-V-based purosesa, idayambitsa maziko atsopano a RISC-V CPU mu mzere wa SiFive Performance, womwe ndi 50. % mwachangu kuposa maziko apamwamba a P550 ndipo ndiwopambana pakuchita ARM Cortex-A78, purosesa yamphamvu kwambiri yotengera kamangidwe ka ARM. Ma SoCs ozikidwa pachimake chatsopano amangoyang'ana makina a seva ndi malo ogwirira ntchito, komanso ndizotheka kupanga mitundu yovumbulutsidwa yazida zam'manja ndi zophatikizidwa.
Zanenedwa kuti, poyerekeza ndi P550, purosesa yatsopano ya SiFive ili ndi 16 MB ya L3 cache m'malo mwa 4 MB, imatha kuphatikiza mpaka 16 cores mu chip imodzi m'malo mwa 4, imagwira ntchito pafupipafupi mpaka 3.5 GHz m'malo mwa 2.4 GHz, imathandizira kukumbukira kwa DDR5 ndi basi ya PCI-Express 5.0. Kamangidwe kake ka pachimake chatsopano ali pafupi ndi P550 komanso ndi modular mwachilengedwe, kulola midadada yowonjezera yokhala ndi ma accelerator apadera kapena ma GPU kuti awonjezedwe ku SoC. Zambiri zakonzedwa kuti zisindikizidwe mu Disembala, ndipo deta ya RTL yokonzeka ndi FPGA idzasindikizidwa chaka chamawa.
RISC-V imapereka makina otseguka komanso osinthika owongolera makina omwe amakulolani kuti mupange ma SoCs otseguka kwathunthu ndi ma microprocessors kuti mugwiritse ntchito mosasamala, osafunikira malipiro kapena kuyika mikhalidwe yogwiritsidwa ntchito. Pakadali pano, kutengera mafotokozedwe a RISC-V, mitundu 2.0 ya ma microprocessor cores, nsanja 111, 31 SoCs ndi ma board okonzeka 12 akupangidwa ndi makampani ndi madera osiyanasiyana omwe ali ndi zilolezo zosiyanasiyana zaulere (BSD, MIT, Apache 12).
