AMD Navi 31 RDNA3 GPU Pictured
Here's the first picture of the "Navi 31" GPU at the heart of AMD's fastest next-generation graphics cards. Based on the RDNA3 graphics architecture, this will mark an ambitious attempt by AMD to build the first multi-chip module (MCM) client GPU featuring more than one logic die. MCM GPUs aren't new in the enterprise space with Intel's "Ponte Vecchio," but this would be the first such GPU meant for hardcore gaming graphics products. AMD had made MCM GPUs in the past, but those have been packages with just one logic die, surrounded by memory stacks. "Navi 31" is an MCM of as many as eight logic dies, and no memory stacks (no, those aren't HBM stacks in the picture below).
It's rumored that "Navi 31" features one or two SIMD chiplets dubbed GCDs, featuring the GPU's main number crunching machinery, the RDNA3 compute units. These chiplets are likely built on the most advanced silicon fabrication node, likely TSMC 5 nm EUV, but we'll see. The GDDR6 memory controllers handling the chip's 384-bit wide GDDR6 memory interface, will be located on separate chiplets built on a slightly older node, such as TSMC 6 nm. This is not multi-GPU-a-stick, because both SIMD chiplets have uniform access to the entire 384-bit wide memory bus (which is not 2x 192-bit but 1x 384-bit), besides the other ancillaries. The "Navi 31" MCM are expected to be surrounded by JEDEC-standard 20 Gbps GDDR6 memory chips.

GPUs are "released in early December".

For what it's worth...
Some people remove the stock cooler and use full length waterblocks for a custom cooling loop. Often people who do so will periodically clean the waterblock which requires removal and disassembly.
For typical users who stick with the stock cooler, there is rarely a need to reapply thermal compound unless cooling performance drops precipitously after time.
I certainly wouldn't buy a graphics card based on the whether or not the GPU package looked like it was conducive to thermal paste application. But apparently it's a big deal for some people online. That's fine: it's their money.
just a "die shot"
But of course, its never AMD's fault.
