SiFive readies U8-Series RISC-V core designs to compete with ARM's Cortex-A72 models

[Redaktion]

RISC-V processors have come a long way since their inception in 2010. Once thought to be significantly slower than the x86 and ARM counterparts, RISC-V processors like the new U84 from SiFive prove that this architecture is catching up very quickly and could become competitive in a few years.

Seeing these numbers I had to go look into their slides, and judging from the only slide with a bar chart, their phrasing of "boosts performance by 3.1 times" should be clarified to be "3.1 times the performance", similarly "2.3 times increased instruction-per-clock" should be "2.3 times the IPC", "1.4 times higher frequencies" is rather "40% higher frequencies", and "1.5 times better performance per Watt" is also probably "50% better performance per Watt".
