• AMD's new 7950X3D can deliver up to four times the gaming performance of the regular 7950X... When using the integrated graphics. (WCCFTech)
  
  Which is weird, but more importantly highlights the fact that the integrated graphics on AMD's desktop CPUs provide only one sixth the performance of their laptop chips. That means they're slower than the integrated graphics on Intel's desktop chips, and you shouldn't buy one expecting to be able to play games without a separate graphics card.
  
  Actually, something about those benchmark numbers doesn't add up; the scores on the regular AMD chips are too low; they should be much closer to the Intel scores.

• Meanwhile AMD's 7945HX is faster than Intel's 13980HX while using 40% less power and has the same crappy integrated graphics as the desktop version. (WCCFTech)
  
  The 7945HX is a 16 core laptop chip that uses as much as 120W, which is fine for a desktop but a lot for a laptop. The 13980HX is a 24 core laptop chip that can use more than 200W, which is simply too much.
  
  
  
• PCIe 5.0 SSDs are finally here. Don't buy one. (Tom's Hardware)
  
  For the $350 price of a 2TB PCIe 5.0 SSD you can get two 2TB PCIe 4.0 SSDs, run them in RAID-0, get 40% better performance and twice the capacity, and still have a little money left over.
  
  PCIe 5.0 will matter eventually, but it's not used in the one place it would actually make sense, on the connection between the CPU and the chipset. Both AMD and Intel have kept that at PCIe 4.0, because PCIe 5.0 costs too much and runs too hot. Though all their current desktop chips support it.
  
  
  
• The Resonance Theory of Consciousness is one of the dumbest things I've ever seen. (Frontiers in Human Neuroscience)
  
  This came up in a YouTube channel I've been watching lately, and it's like explaining how cars work by studying only the noise they make. Cars make noise when they move, therefore it's the noise that makes them move.
  
  It's cargo cult science.
