• Is it a bubble? Let's ask the money men lending billions to build these AI datacenters.
  
  They say yes. (New York Times) (archive site)
  
  9.25% interest rates for commercial construction loans that supposedly have paying customers lined up?
  
  Yeah, they're not convinced.
  
  
  
• The people who backed French bugfarm Ÿnsect were convinced - to the tune of $600 million. (Tech Crunch)
  
  And lost their shirts, because the idea was irredeemably stupid.

• The Ryzen 5000 series of CPUs - now five years old - have become top sellers as users choose to stick with their older memory and upgrade the rest of the system. (Tom's Hardware)
  
  AMD stopped making the 5800X3D probably because it was too competitive against newer models. Maybe they'll consider restarting production if nobody can afford memory for the new models, which are DDR5-only.
  
  Intel's 12th through 14th generation CPUs support both DDR4 and DDR5 depending on the motherboard.
  
  DDR4 memory is also astronomically expensive as well - though not quite as bad as DDR5 - but people likely already have it. A relative mentioned he'd recovered at least 50 DDR4 modules from PCs being scrapped at the office, and he's not alone in that.
  
  
  
• AMD's long-rumoured 9950X3D2 CPU - with dual 3D V-cache modules - has started showing up in benchmark results. (Tom's Hardware)
  
  It's only about 2% faster than the regular 9950X3D on general benchmark results, which is precisely why AMD hasn't produced such a chip before. The company already sells server chips with V-cache on every CPU die, so it was always possible, just not useful in most cases.
  
  
  
• AMD's next-generation RDNA5 graphics chips are taped out (design completed) ready to start mass production of the chips in the second half of next year, with cards shipping in 2027. (WCCFTech)
  
  The lead time on bringing something like this to market is pretty long.
  
  We may also see higher-end models this time, given the fairly warm reception of the current RDNA4 series.
  
  They will, of course, be expensive.
  
  
  
• There's a new security vulnerability in MongoDB if you are silly enough to be running it on public-facing internet servers. (Double Pulsar)
  
  Solution: Don't do that.
  
  
  
• LG has also announced 5K gaming monitors (though two of them are ultrawide models - 5120x2160 rather than 5120x2880). (Notebook Check)
  
  All with high refresh rates, so the graphics card you can't afford in the computer you can't build won't be able to keep up but if you just need a new monitor and plan to hang onto it after the present insanity dies down, the 27" model might not be bad.
