nouvelles nvidia RTX

Lately, the rumors about the upcoming RTX 4000 from NVIDIA have been crazy, with specifications and power consumption changing almost constantly, going from 450 TDP to 600W, even up to 900W, then, we heard that it was no longer the TDP but the power limit… In short a real quagmire.

Today, we return to the latest information we have on its cards, with the leaker kopite7Kimi, which so far has been one of the most reliable in a multitude of other twittos or YouTubers, despite some previous statements that he then rectified. https://twitter.com/kopite7kimi/status/1543844605531418625 So as of July 4, the specifications of the upcoming RTX 4090, 4080 and 4070 are as follows:

  • The RTX 4090 would have an AD102-300-A1 chip with 128 SM on the 144, with 24 GB of GDDR6X at 21 Gbps on a bus has 384 bit, entering a TDP of 450W. The boost frequency would exceed 2750 MHz.
  • The RTX 4080 would use the same chip but with 80 SM, supported by 16 GB GDDR6X at 21 Gbps on a 256 bit bus, in a TDP of 420W.
  • The RTX 4070 would use an AD104-275 chip with 56 active SM and 10 GB of GDDR6 at 18 Gbps and a 160 bit bus, the TDP of this card would be 300W.

Specifications that seem tempting especially for the 4090. As a reminder, the 3090 Ti that use the full GA102 chip has 84 SM, 44 less than the potential 4090 which would not be the largest GPU! Of course, we must take all this with a pinch, despite the reliability of the leaker.
