NVIDIA is reportedly working on a new H30 AI GPU for the Chinese market, with rumors suggesting it'll be using GDDR memory and not HBM memory.

In a new post on X from insider @Jukanlosreve, supply chain sources teased: "on the other hand, NVIDIA is preparing a China-specific version of the B30, which uses GDDR instead of HBM -- similar to the previous L40S. However, it is still uncertain whether it will be released".

Not much to go on at all, but it is an interesting thought: NVIDIA replacing the higher-speed, higher-end HBM memory for GDDR memory (which is getting faster and faster, with the likes of GDDR7 launching on its GeForce RTX 50 series GPUs).

@Jukanlosreve replied to his new post about the purported H30 AI GPU, to a post he did on May 4 saying that NIVDIA's new B20 replacement wouldn't have HBM. The insider said that the Trump administration placed restriction on HBM, "making it impossible to use the latest HBM".

He continued: "That means they'd have to use older HBM, but Samsung, the only supplier still theoretically capable of producing older HBM like HBM2E, is already phasing those out. It's highly unlikely Samsung would keep producing obsolete HBM just for NVIDIA. But even so, an AI chip without HBM would inherently suffer from severely limited performance, in my opinion. So I wonder-even if they launch it, would it actually sell well?"
