AMD's RX 7000 series Navi 31 CPUs are ready for a 3D V-Cache upgrade
3D packaging could soon come to Radeon

AMD has laid the groundwork for future GPUs with 3D stacked memory cache dies
AMD's "Navi 31" RDNA 3 graphics cards are incredibly innovative, and while their Radeon RX 7900 XTX has failed to surpass Nvidia's RTX 4090, AMD has managed to introduce many key design enhancements that could allow AMD to surpass Nvidia in the future. One of these design tweaks is AMD's successful chiplet-based design approach, and the second is hidden within their memory cache dies.
Tom Wassick has analysed AMD's Navi 31 Infinity Cache Dies and has confirmed that they feature "spots" that are useful for 3D chip stacking. This is the technique that AMD has used to add 3D V-Cache to their Ryzen 5000 X3D and Ryzen 7000 X3D processors, suggesting that AMD has plans to add 3D V-Cache to their memory cache dies. In theory, AMD could release a Radeon 7000 series GPU with 3D V-Cache on their memory cache dies, increasing their available Infinity Cache to boost memory performance.
While AMD's obvious use for this 3D stacking functionality is the addition of more Infinity Cache, it is possible that AMD could put 3D stacking to another use, though at this time we have no idea what this use could be.
Currently, it is unknown when AMD plans to utilise 3D chip stacking with their Radeon graphics cards. AMD could utilise 3D chip stacking with future RX 7000 series GPUs, or wait for the release of their future RX 8000 series before utilising this feature. Either way, AMD has plans to release more complex GPUs in the future, and 3D stacking could take their Infinity Cache technology to the next level.

i need better compatibility and support for my applications.
even a 15% faster card for the same price would not make me buy an AMD GPU.Quote

but AMD puts a lot of effort into supporting game development.
i don´t see them do the same when it comes to applications.
it´s one thing to have tools availabe, another to have actual help from engineers.
nvidia seems to be way ahead when it comes to supporting software companys.Quote
Having cutting edge hardware is one thing, having the resources to back it up and support it in a timely manner is another.Quote
