Rumor | Nvidia RTX 3000 Titan with 48 GB of GDDR6x VRAM may launch to counter AMD's "Biggest Navi" GPU in Q1 2021

AMD's "Biggest Navi" is rumored to be similar to the Radeon VII, featuring HBM2 VRAM and 80 compute units, and Nvidia is apparently planning to counter this with an RTX 3000 Titan GPU equipped with up to 48 GB of 21 Gbps or even 23 Gbps GDDR6x VRAM that may turn out to be only 10% faster than the RTX 3090.

From what we have seen leaked thus far, the “Big Navi” GPUs from AMD are not really matching the performance of the Nvidia RTX 3080. However, new rumors coming from Moore’s Law is Dead now suggest that the “Big Navi” might not be AMD’s top-of-the-line product, so we could see an even more powerful card, the “Biggest Navi” if you will, launching in early 2021, and Nvidia is apparently preparing a Titan GPU to counter it.

Tom from Moore’s Law is Dead is suggesting that the specs of the “Biggest Navi” could include the rumored 80 compute unit cluster that might not make it into the "Big Navi" models, along with HBM2 VRAM instead of GDDR6/x. Sounds like this could be similar to the Radeon VII that had very limited availability and targeted the semi-professional / ultra-high-end gaming markets.

If that turns out to be the case, what specs would Nvidia plan for the Titan? Tom thinks that GDDR6x is a must, either with 21 Gbps or the upcoming 23 Gbps variants scheduled to be released in Q1 2021. VRAM capacity could be as high as 48 GB, just like the leaked Quadro 6000 professional GPUs, while TGP ratings could be around 370 W. Still, if Nvidia wants to use the new 23 Gbps memory, the Titan would probably include only 44 GB with a 352-bit bus. Price-wise, the Titan would cost less than the Quadro 6000, maybe around US$3,500, whereas the performance improvements over the RTX 3090 could be in the ballpark of 10%.

I stepped into the wonderous IT&C world when I was around 7. I was instantly fascinated by computerized graphics, be them from games or 3D applications like 3D Max. I like to keep myself up to date with all the new technologies that get released at an ever increasing rate these days. I'm also an avid SciFi reader, an astrophysics aficionado and, as of late, a crypto geek.
