AMD’s RX 7900 XT Will Have 7 CHIPLETS (Dies)?

Let's get started with some GPU news. And today we got a bunch of stuff for the triforce of Graphics companies. Starting with the green team, we have an April fools joke turned into a leak. Kopite7Kimi over on Twitter had an April's fool tweet that was all about the next generation of NVidia’s GPUs. It basically broke down into the 70-80 and 90 series. Now, once again, this was a joke-ish tweet but here are the specs. 12GB of Vram for the 4070 series, 20Gb for the 4080, and 24Gb for the 4090. All at a blazingly fast 24Gbps. Yeah, that seems optimistic, especially the 24Gbps part. GDDR6X is already dangerously hot, getting it up to 24Gbps seems like a way to introduce flames into your system’s esthetics.[...]

Then we have AMD in the news because their GPU is apparently going to push chiplets to the next level. We already know that AMD’s next step in the GPU game is to split up the graphics chip into smaller chiplets. I mean, they’ve already done it on their CDNA based Instinct MI250X. But it looks like for Navi 31, the company might take another leap in the technology. Now, this information comes from leaker extraordinaire, Greymon 55, and essentially, he’s saying that Navi 31, the highest end of AMD’s next-gen, will have 7 chiplets on a substrate. 7! That’s a lot of chiplets for a consumer part.

As is, we already know that 2 of them are the graphics cores. They would be built on the TSMC 5nm process. According to what we know so far, the third chiplet should be the interconnect, or the IO die built on TSMC’s 6nm process. But he said theres 7, so what could the other 4 be? Well, he says they’re called MCD’s. One guess would be Memory Complex Dies. As in, this could be for HBM memory, but I dont think AMD is taking a chance like that again. I mean Raja did a number on them with HBM. [...]

Lastly we have intel in the news. And we’re talking future Xe GPU’s. Redfire over on twitter took the information currently available from old and newer leaks and from intel documentation and made an educated guess at what Battlemage could be.

Battlemage by the way in the generation of GPU’s that is coming after Alchemist in around 2023 or 2024. Anyways, with intel’s tile system, a 2 tile version of Battlemage would have 10240 Vector engines, that’s like Intel’s Cuda cores, and with 4 tiles, we could see 20 480 Vector engines.

This might seem like an insane amount, but we’re looking at 2023 slash 2024. AMD and Nvidia will already cross the 15000 fp 32 cores by 2023. So if they want to compete in the high end, this is intel’s chance. Redfire does say that the 2 tile config is the most likely though, especially since intel did say that Battlemage is for Enthusiasts but not necessarily Ultra enthusiasts.
