The NVIDIA RTX 5090 will not rely on a Chiplet architecture: Blackwell will be monolothic [Rumor]

After dominating the PC gaming market with the RTX 40 “Ada” line, NVIDIA will also stick to a monolithic design with its upcoming RTX 50 series. Codenamed Blackwell, these graphics cards are expected to arrive in late 2024 or early 2025. Sources say Team Green will leverage TSMC 3nm-class processing technology, as well as GDDR7 memory and a wide bus.

ADA-next appears to be another monolithic chip.

According to @kopite7kimi, Ada-Next (Blackwell) appears to be another monolithic chip rather than a chiplet design. AMD's RDNA 3 range already uses a chiplet architecture with a GPU and several disaggregated memory/cache controllers. Intel opted for a monolithic design with its first-generation Arc Alchemist family, but plans to move to a tiled architecture with the successor Battlemage family.

Maybe Blackwell.

It's too early to predict Blackwell's specifications, but you can be sure that there will be radical changes to the memory and computing unit. Kimi thinks we could see a massive 512-bit memory bus, larger than anything seen on single-disk GPUs. The memory will also upgrade to GDDR7 technology, which will significantly improve bandwidth.

It's still too early to talk about Blackwell. I wouldn't be surprised if it has a 512-bit memory interface.

We could even see external bandwidths of up to 2 TB/s on high-end components. The SM hasn't undergone any notable changes over the past two generations, so there's a good chance it will be overhauled this time around.
