Latest MLID video
Some bits he claims from his sources
* There is a lot of RTX4090 stock for launch day and the cards are unlikely to sell out on the 1st day
* Reviewers MLID spoke to are very impressed; the 4090 is average 80% faster than the 3090 in rasterisation games and 100% faster in ray traced games.
* The 4090 is much better at power management and doesn't have lots of huge transient spikes like the 3090 and reviewers say if your system can handle a 3090 already you can just drop a 4090 in. The 4090 also apparently undervolts very well.
* MLID also says there will be no 4090ti or Titan, it's been cancelled because Nvidia doesn't think AMD can touch the 4090. The full AD102 GPU would have had a 600w to 700w TDP and being four slots and test models in the lab had overheating problems
MLID also has released photos of a FE 4070 (in the video)
