Posted by Clamshell VRAM design?

AMD, make a 384-bit GPU (like a 4090 24 GB is one), with GDDR7 and put the GDDR7 memory chips on both sides of the PCB (aka VRAM clamshell design). A 1 TB/s, 48 GB VRAM, consumer GPU will be very interesting for hosting LLMs privately and locally. llama.cpp Vulkan build run LLMs just fine, CUDA is not needed for endconsumer AI inferenceing.

QuoteMLID suggests that AMD might not want to lose this advantage by launching an RX 9080 XT with 32 GB of GDDR7 VRAM.
But AI folks want GDDR7 for higher memory bandwidth per same bit bus width. Don't waste the GPU silicon chip by connecting slower GDDR6 memory chips to it.

Is this rumored 32 GB card using a 256-bit GPU chip (= natively 16 GB VRAM) and is doubling the VRAM by using clamshell design? At least the name jump may suggest so? Otherwise it would be called RX 9090 XT. Or is that a native 32 GB card (= uses a 512-bit GPU chip, just like a RTX 5090 one is)?

Yes, there is: Running AI/LLMs locally and privately. Also, the obvious thing is that a 5090 exists, people buy it and AMD is losing on those sales.

Specs make no sesne. 32GB would target 5090. There's no need for that. A 9080XT with 20GB or 24GB GDDR6 and 20% more CU's would be more than sufficient to compete with 5080/Super and keep price in check.

Nvidia is reportedly gearing up to launch the RTX 50 Super series GPUs as a refresh of the RTX 50 series boards. While AMD has officially revealed no new GPU plans, Moore's Law Is Dead leaked new RDNA 4 cards that could be in the works. The leaker now thinks that the plan might get changed.
