alt Hacker NewsIf I'm reading their chart right, they have barely half as much memory for their RISC-V machine compared to any of the others? I don't know enough to know whether it's actually bottlenecked by memory, but it's a bit odd to claim it's slower, give those numbers, and not say anything about it. I'd hope they ruled that out as the source of the discrepancy, but it's hard to tell without confirmation.
I think it's mentioned clearly in the article.
> RISC-V builders have four or eight cores with 8, 16 or 32 GB of RAM (depending on a board)
> The UltraRISC UR-DP1000 SoC, present on the Milk-V Titan motherboard should improve situation a bit (and can have 64 GB ram).
RISC-V SOCs just typically don't support much ram. With the exception of the SG2042 which can take 128GB, but it's expensive, buggy and now old.
So I am sure it's a combination of low ram and low clockspeeds.
