NVIDIA Prepares Blackwell B30A for China: Faster Than H20 Yet Half the Performance of Blackwell Ultra B300

NVIDIA is reportedly in the final stages of designing a brand-new Blackwell chip tailored for the Chinese market, dubbed the B30A. This forthcoming chip is set to supersede the Hopper-based H20 while boasting improved performance metrics.

NVIDIA’s Blackwell B30A: A Replacement for H20 in China, Outclassed by B300

As highlighted by Reuters, NVIDIA’s latest design is compliant with U. S.regulations, allowing for its launch in China. The B30A will outperform the existing H20 but will provide considerably lower performance relative to the high-end Blackwell models, specifically the B200 and the anticipated B300.

The Blackwell B30A will utilize a single-chip architecture, distinguishing it from the dual-chiplet designs found in the more advanced Blackwell B200 and B300 models. Notably, the NVIDIA Blackwell Ultra B300 is expected to deliver 50% greater performance than the B200, include 50% additional memory, and feature double the interconnect speeds. Its flagship configuration will consist of dual GPU chips combined for an impressive 15 PetaFLOPs of FP4 compute capability, alongside up to 288 GB of HBM3e memory.

The new chip, tentatively known as the B30A, will use a single-die design that is likely to deliver half the raw computing power of the more sophisticated dual-die configuration in Nvidia’s flagship B300 accelerator card, the sources said.

A single-die design is when all the main parts of an integrated circuit are made on one continuous piece of silicon rather than split across multiple dies.

The new chip would have high-bandwidth memory and Nvidia’s NVLink technology for fast data transmission between processors, features that are also in the H20 – a chip based on the company’s older Hopper architecture.

The performance expectations for the B30A indicate a potential configuration with up to 144 GB of HBM3e memory, surpassing the H20’s 96 GB capacity. However, it’s worth noting that the B30A may feature 41% fewer cores and exhibit a 28% drop in performance compared to the Hopper series’ H100 setup.

While NVIDIA has yet to finalize specifications for the B30A, reports suggest that early samples are slated for delivery to a Chinese client as soon as next month. Anticipation is building in the Chinese market, with demand for the B30A chip reportedly on the rise ahead of its official release.

In a recent statement, U. S.President Donald Trump hinted at the possibility of a downgraded version of the Blackwell chip being provided to China. He indicated that he would be discussing terms with Jensen Huang, NVIDIA’s CEO, and is contemplating a deal contingent on imposing a 15-20% tariff on these chips. His comments include:

And Jensen also has a new chip, the Blackwell. You know what the Blackwell is? The Blackwell is Super Duper Advanced. I wouldn’t make a deal with that, although, it’s possible I’d make a somewhat enhanced, in a negative way, Blackwell.

In other words, take 30% to 50% off of it. But that’s the latest and greatest in the world. Nobody has it, they won’t have it for five years. But the H20 is obsolete. You know it’s one of those things but it still has a market. So I said, I want 20% if I am going to approve this for you, for the country, for our country, for the US. I don’t want it myself. You know, every time I say like 747, I want, I want, for the Air Force. So when I say I want 20, I want for the country. I only care about the country, I don’t care about myself. And he said would you make it 15. So we negotiate a little deal.

So he’s selling an essentially old chip that Huawei has a similar chip, a chip that does the same thing. And I said if I am going to give it to you because they have a stopper, what we call a stopper, not allowed to do it, restricted, it’s really known as a restrictive covenant, and I said if I’m going to do that, I want you to pay us, a country, something. I am giving you a release, I release them only from the H20.

Now, on the Blackwell, I think he’s coming to see me again about that but that will be an unenhanced version of the big one.

As we look forward to the arrival of the B30A, the finalized specifications will determine how it compares with its high-performance counterparts. The forthcoming months will be crucial as NVIDIA asserts its presence in the competitive Chinese chip landscape.
