hotaru251 this sounds like a lawsuit in waiting. If you paid for a 140core one and they force you to downgrade you no longer getting what you paid for and them purposefully cutting down your hardware via firmware w/o compensation seems a slippery slope. Reply

ezst036 This is why I think my next rounds of upgrade in the future need to have mandatory OpenCORE, or Linux BIOS, or whatever open source firmware. Or I am not buying. None of these companies can be trusted. Even the relatively small guys like Tenstorrent. What a bunch of dishonest crooks. Open drivers, open firmware. Or BUST! We as consumers deserve to have a fully open stack from top to bottom to help serve as a bulwark against chicanery. All these companies can go pound sand. Reply

DS426 Goodness sakes, why can't these companies just communicate the "why"? The lack of transparency definitely destroys trust, not to mention just being highly uncourteous. Reply

thestryker The fact that they're citing 1-2% performance loss would indicate something is bottlenecking the existing design. I'd be surprised if they were spinning up new silicon this late in the hardware cycle so it does leave lots of questions. I've seen some hypothesis that this is potentially related to power consumption/cooling. Regardless there should be some sort of indicator as to why it's being done in the first place. Reply

Forge64 Always a great idea, making changes to a product after shipping, and then I always like to really make the users comfortable by dictating changes to them, and telling them "stop asking questions, it's going to be great" when they pester me with concerns. Just 10/10 handling all around. No notes. Reply

Key considerations

  • Investor positioning can change fast
  • Volatility remains possible near catalysts
  • Macro rates and liquidity can dominate flows
