What could be more impressive than a 24GB Nvidia GeForce RTX 3090, a GeForce RTX Titan with 48GB of GDDR6X video memory?

At least YouTuber Moore's Law is Dead suggested that Nvidia could come up with a counterpart to the AMD Big Navi Radeon RX 6000 series of ultra high-end graphics cards. Using a combination of insider information and speculation, the chip-centric YouTuber stated that AMD plans to release a "Biggest Navi" graphics card in 2021, which Nvidia will need to respond to.

Currently, Nvidia has three graphics cards that make up the new GeForce RTX 3000 series lineup: the RTX 3090, RTX 3080, and RTX 3070. The first is a $1,499, 24GB high-end monster graphics card, and the second is a $699 card that considerably outperforms the RTX 2080 Ti. The RTX 3070 does the same thing to a lesser degree and for a much lower price of $499.

We expect Big Navi, now known as AMD's Radeon RX 6000 series, to offer a graphics card that could approach the performance of the RTX 3080, but at a potentially lower price. In other words, AMD does not yet have a graphics card that challenges the RTX 3090.

There is an argument that the ultra-high end cost of the RTX 3090 means that it will not be the mainstream GPU that AMD needs to compete with. However, self-praise in the graphics card arena is very real. That said, Moore's Law is dead, and we expect to see new Navi graphics cards in 2021 that offer 80 compute units and utilize HBM2 VRAM.

Such graphics cards will likely be targeted at very high-end PC gaming enthusiasts and professionals who do graphics-intensive work, such as CAD, if AMD's Biggest Navi GPU outperforms the RTX 3090, Nvidia will surely want to respond.

Also, based on information that memory maker Micron will make 23Gbps GDDR6X memory available by early 2021, Moore's Law suggests that Nvidia could produce an RTX Titan card with twice as much VRAM as the RTX 3090 This is a very good thing. In doing so, using the 352-bit memory bus facilitated by Nvidia's new Ampere architecture, the new RTX Titan would achieve a massive throughput of 1012 GB/s and hit the 1 TB/s milestone.

This would create a ridiculously powerful graphics card that would probably cost thousands of dollars. However, having seen Nvidia develop the RTX Titan for the current Turing generation of GeForce cards, there is room for Ampere to do the same.

But this is all pretty heavy speculation; the RTX 3090 is already touted as being capable of up to 8K gaming, which is already a pretty ridiculous goal given the lack of 8K displays.

We will have to wait for the full Radeon RX 6000 series announcement on October 28 to find out what AMD has been working on and whether Nvidia needs to prepare for its rival.
