The GPU rumor mill is slowly heating up and providing additional information on the expected next-gen high-end models Nvidia GeForce RTX 4090 aka Ada (Lovelace), AMD Radeon RX 7900 XT based on RDNA 3 and Battlemage, the second generation of GPUs from Intel, which should also be based on a multi-chip module.
More details about Ada and Navi 3x
While rumors of the Nvidia GeForce RTX 4080, 4080 Ti, and 4090, which recently spoke of high total graphics power (TGP) of 450, 650, and 850 watts, of which 450 watts alone would be reserved for Nvidia’s AD102 GPU , and the AMD Radeon RX 7900 XT hybrid, which would offer up to 15,360 shaders in the MCM design, has meanwhile become increasingly established, according to Twitter users @Greymon55 and @kopite7kimi additional replenishment.
*) not officially confirmed!
Until now, it was assumed that Navi-3x GPUs would get by with two GDC dies and three MCD dies and no I/O dies. There is still no real clarity on this issue.
two 5nm GCDs
four 6nm MCDs
an interconnected controller
7 chips in total

Additional info on the structure of Navi 31 also comes from the Reddit subreddit r/AMDGPU Here too, two GDC arrays with 7,680 shaders each and four MCD arrays with 512MB (4x 128MB) Infinity Cache and an I/O – The speculated.
GCD – Graphic Chiplet Die
MCD – Memory chip to chip
IOD – IO Matrix
4x MCD 128MB SRAM cache
(512 MB total)
1x integrated IOD crossbar
500 GB/s GCD to MCD
(total of 2 TB/s)
4 MCD HBM 400 Gb/s stacks
(1.6 TB/s total)

The AD102, which would lead the GeForce RTX 4000 (“Ada”) series as the largest GPU, continues to follow a classic monolithic approach.

Specs that have yet to be confirmed by Nvidia also come from posts by @Greymon55 and @kopite7kimi, the latter now being supplemented by the designation of the three graphics processors. According to this, the top model with A102-300 should be equipped with 24 GB 21 Gbps GDDR6X accelerated graphics memory.

Intel Battlemage simmers in rumor
Like the website video cardz reported, early rumors about Intel’s penultimate generation of GPUs, aka Battlemage, are already simmering in the rumor mill.
While Nvidia and AMD are expected to reach 18,432 and 15,360 shader units respectively with their next-gen GPUs, the Twitter user reports @Redfire75369 up to 20,480 ALUs for the full expansion based on the Intel Xe2-HPG architecture, which is expected to follow Alchemist in 2023-2024.
Configurations with 5,120, 10,240, and said 20,480 Xe-2 shaders should be based on up to four matrices or tiles in the MCM design. Even more than Ada and RDNA 3, Xe2-HPG (“Battlemage”) is still a dream of the future.
Rumors should be treated with caution
Even though both protagonists have had a very good rate of “predictions” of GPU specs in the recent past, the latest rumors should still be treated with a lot of caution. AMD, Nvidia, and Intel have yet to release concrete information on the graphics chips and architectures being discussed.
