Daily News Stuff 5 February 2025

• AMD shares slid 5% on the market after annual results revealed a 14% increase in revenue and a 92% increase in net income. (Thurrott)
  
  Because analysts were expecting even more.
  
  Maybe at some point greed stops being good.

• Using the time-tested method of hitting things with stuff, physicists have confirmed the existence of a third form of magnetism. (Science Alert)
  
  Termed altermagnetism, the individual atoms in the crystal lattice have their quantum spin in opposite directions to their neighbours, but with a novel twist, that they don't explain very well and which I don't understand but can apparently be used to store data somehow.
  
  
  
• Australia has also banned Chinese spyware DeepSeek from government devices. (The Register)
  
  The country also moaned bitterly that nobody takes it seriously when it says the internet can be used to look at naughty pictures.
  
  
  
• Plugging a handheld gaming device into a dock with an Nvidia RTX 5090. (The Verge) (archive site)
  
  First, it actually worked, and second, it worked pretty well for the most part. On Horizon Zero Dawn it saw a significant loss of performance compared with a desktop system with a 5090, which may have been the OCuLink connection or may have been the thermal limits of the pocket-sized device.
  
  The 5090 itself offers a PCIe 5.0 x16 connector, but OCuLink only provides PCIe 4.0 x4 - one eighth as much bandwidth. Tests have showed that the 5090 keeps chugging right along with PCIe 4.0 or 3.0 x16 slots, but this is half that again.
  
  So if you really need to play Horizon Zero Dawn on your handheld device plugged into a desktop graphics card that it is not currently possible to buy, you may be limited to just 80fps.
