NVIDIA would prepare a GeForce RTX 4090 Ti with 18,176 cores and 48 GB of GDDR6X

A GeForce RTX 4090 Ti or Titan, for now simply called “The Beast”. Board TBP: 800W

To justify the increased appetite for the Radeon RX 7000s, Sam Naffziger, who works for AMD, accuses NVIDIA of indulging in a power outbid for its future GeForce RTX 4000s. In a recent Tweet, Kopite7kimi suggests specifications that go in this direction : NVIDIA is preparing a GeForce RTX 4090 Ti or Titan, called The Beast, at the TBP (total board power) of 800 W.

The latest rumors for the GeForce RTX 4090 agree on a TBP of 450 W. The difference between these two references would therefore be quite staggering. In terms of stream multiprocessors, The Beast would only have 13% more units (142 SM against 126, or 18,176 CUDA cores against 16,384). It would be especially at the level of the VRAM that the disparity between the two references would be great. Kopite7kimi mentions 48 GB of GDDR6X, twice as much as for the RTX 4090, which is also clocked at 24 Gbit/s instead of 21 Gbit/s.

For the current series, the most powerful card is the GeForce RTX 3090 Ti with 24 GB of 21 Gbps GDDR6X. On a 384-bit bus, this memory gives it a bandwidth of 1008 GB/s. GDDR6X at 24 Gbit/s on the same bus can exceed 1.1 TB/s.

Priority to the GeForce RTX 4090

If this card sees the light of day, it is likely to be at the end of the cycle, like the GeForce RTX 3090 Ti. Initially, NVIDIA will likely launch the GeForce RTX 4090, RTX 4080, and RTX 4070. In June, rumors included an August launch by the former; Kopite7Kimi seems to agree. Note, however, that other sources are rather counting on a postponement due to GeForce RTX 3000 stocks to be sold.
