  I wonder how many boards are stacked up here, 17kg
• 16:33
  DataHoarder
  oh, same weight as their previous board stack, but 200 -> 1000 KH/s they advertise

  So they claim 400 h/s/watt basically
• 16:50

  Interesting
• 16:51

  Best tuned EPYC systems get 200-250 h/s/watt

  let's fork!

  My plan is to finish RandomX V2 in Q1 2026 :P

  FCMP++ already has the commitment stuff in the pipeline

  RandomX v2 is missing the RISC-V code, but this is exactly what I've been working on in December
• 16:51
  kico
  thanks for doing the needful sir _/\_

  V2 probably if ready
• 16:52
  DataHoarder
  V2 is "minor" overall, the AES part + rounding changes
• 16:52

  There might be some other changes ;)
• 16:52
  DataHoarder
  ;)

  would be fun to brick these inb4 release
• 16:52

  I think it should be tuned for Zen4/Zen5/Zen6 CPUs
• 16:52

  *tuned more
• 16:53

  As it's the main source of RandomX hashrate now, and ZenX CPUs will dominate the CPU market in the next 5 years or so
• 16:53
  DataHoarder
  AVX512 128-bit specific masked operands :)
• 16:53
  DataHoarder
  so 128-bit conditional lanes, which also exist in other instruction sets
• 16:54
  DataHoarder
  kico: if they are some RISC-V tbh they are "cpu"s so unless they cheap out on what they include it can probably adapt
• 16:54
  kico
  DataHoarder, yeah I mean a fork could at least make them less profitable
• 16:54
  kico
  "brick" was not the best word
• 16:55
  kico
  they could need a FW update to adapt no?
• 16:55
  DataHoarder
  I mean, if they are after all just plain old CPUs just more power efficient
• 16:55
  kico
  sure
• 16:55
  DataHoarder
  purpose of randomx about "someone implementing this just needs to make a more efficient CPU than existing"
• 16:56
  DataHoarder
  no ssh needed in a performant way
• 16:56
  DataHoarder
  they can cheap out there
• 16:56
  DataHoarder
  they can kill all their branch prediction to reduce consumption and silicon

  This PR completes XMRig's RISC-V support xmrig/xmrig #3749
• 21:13

  Nothing more to do there
• 21:13

  Now I can focus on RandomX v2 :)
• 21:13
  sech1
  Oh, but first I need to move all new RISC-V code to the upstream repo
• 21:13

  In January probably
