Micron has revealed that it is working on a new super-fast GDDR6X video memory, which will power upcoming next-gen Nvidia GPUs, including the RTX 4090.
While GDDR6X was included in the next-gen RTX 3090 Ti GPU at 21 Gbps, it appears that the RTX 4090, 4080, and 4070 will use this speed of GDDR6X, with the amount and memory bus being different between models.
So, rumors suggest that the GeForce RTX 4070 will come with 12GB of GDDR6X at 21Gbps, along with a 192-bit memory bus.
Rumor has it that the GeForce RTX 4080 will have 16GB of GDDR6X at 21Gbps and a larger 256-bit memory bus.
The Flagship RTX 4090, then, could come with 24GB of GDDR6X memory at 21Gbps and a 384-bit memory bus.
Those numbers alone suggest a big performance boost over the previous generation of Nvidia GPUs – but it looks like Micron is holding back its much faster memory for a mystery Nvidia GPU.
Analysis: What is this mysterious GPU?
The latest leaks have surfaced on Twitter (see below), and they suggest that not only is Micron producing 21 Gbps GDDR6X memory – but also 24 Gbps GDDR6X memory.
If true, that would be incredibly fast memory – and certainly the fastest we’ve seen on a consumer GPU.

But if it’s not coming to the flagship RTX 4090, which many people assume will be the most powerful of the ‘Lovelace’ RTX 4000 series GPUs. So if it’s not going to show up in the RTX 4090, where will it show up?
Current rumors suggest that Nvidia is working on a mystery GPU, which could be a new entry in its Titan graphics card lineup. These are extremely powerful GPUs that straddle the line between consumer gaming GPUs and professional-grade graphics cards, and showcase the best hardware Nvidia has made.
There hasn’t been a Titan since the RTX Titan in 2018, which was built on Nvidia’s Turing architecture.
There was no Titan released during the years of the RTX 3000’s “Ampere” architecture, and many people assumed that the RTX 3090 (and later the RTX 3090 Ti) had replaced it, with better performance and lower price.
However, rumor has it that Nvidia will release an incredibly powerful GPU with 48GB of GDDR6X memory, which could run at those speeds of 24Gbps.
Such a GPU would be outrageously powerful and would dwarf even the mighty RTX 4090 when it comes to power.
Does this mean that this mysterious GPU could have already rendered the RTX 4090 obsolete? After all, many people who plan to splurge on the RTX 4090 are doing so because they want the best cutting-edge technology from Nvidia.
Instead, they might be tempted to opt for this much more powerful GPU. However, it’s worth pointing out that these specs suggest a GPU that would offer more power than anyone really needs right now. For playing PC games, then, that spec would be a little wasted and you’d end up paying for a GPU you don’t use to its full potential.
On the other hand, if you’re a creative pro who needs some really heavy graphics performance, this can be a great investment. Along with the raw performance, the mystery GPU is likely to be much expensive – and with a power draw of 800W, you’d probably need a new PSU to deal with it – and that’s before we even get into the impact this can have on your energy bills.
So while this mystery GPU is becoming quite exciting, we still think the RTX 4090 will be the ultimate gaming GPU in the end.
