Nvidia RTX 4090 May Not Be as Hot as First Suspected

gamerant.com:

It's safe to say that this current generation of graphics card technology is coming to a close. With both Nvidia and AMD due to launch new hardware this year, the next few months are going to be interesting, as speculations become more inbound. Given how soon team green's next RTX offerings could be hitting the shelves, many are keeping their ear to the ground to see what information, if any, can be gleamed, including details about possible spec.

As reported by PC Gamer, a recent tweet from known industry leaker kopite7kimi has given a summary about what they think the Nvidia RTX 4090 will feature. Using the Ada Lovelace architecture, it's looking like this next generation flagship GPU could have 24 GB of GDDR6X VRAM, on a 21 Gbps memory clock, as previously believed. It could also have 16,128 CUDA cores. At a cursory glance, it seems almost on par with the recently released RTX 3090 Ti, only with more cores. However, one of the other interesting pieces of information is that the 4090 could have a TDP of 450W.

Nvidia GPUs Are Starting To Embrace Linux More

At the start of the month, kopite7kimi speculated that the Nvidia RTX 4090 could require 600W of power, which would make it quite a stifling graphics card. Since then, they've changed that to say that it might be more in-line with the 3090 Ti, featuring a TDP of 450W instead. That's still pretty warm, but a good margin away from what was originally being rumored.

Of course, it should be stated that these details have yet to be announced by Jensen Huang and co, so the details cannot be verified just yet. Having said that, as Nvidia is looking to launch the RTX 40-series this July, it's likely that the products are being built, with specifications close to being finalized.
