The latest update comes from serial Nvidia leaker Kopite7kimi who claims that the expected clocks of the RTX 4090. A 2235MHz base and a 2520MHz boost clock would put it far ahead of the clocks of the RTX 3090 Ti Founders Edition at 1670.
Owners of RTX 30 series cards would know that their rated boost clocks are often exceeded, and that appears to be the case with the RTX 4090. Kopite7kimi claims that the RTX 4090 can boost to at least 2750MHz. Third party cards might even be able to hit the magical 3GHz level with the wind behind it and if it is going downhill.
The 450W TDP is not bad and the extra cores on the 4090 will sink the 3090 and 3090 Ti without taking any architectural improvements into consideration.

The RTX 4070 is an xx70 class card with a 160-bit bus which is a little weird on a modern card. 18Gbps memory should help but 160-bit is too mid-range. With 7168 cores it will beat an RTX 3080, but its 10GB of memory is probably not enough for 4K gaming and large texture packs.
Rumors around the release timeframe are quite variable. We can expect to see the RTX 4090 first with the RTX 4080 and RTX 4070 expected to follow before the end of the year.
