据可靠消息，全球知名的图形处理单元（GPU）制造商英伟达（NVIDIA）计划在明日的GTC 2024主题演讲中，发布名为Blackwell的下一代GPU架构。此次发布预计将包括两款新品：B100和B200。
据悉，B100 GPU将采用两个基于台积电CoWoS-L封装技术的芯片，这一先进的2.5D封装技术能将芯片堆叠在一起，从而提高处理能力，同时节省空间并降低功耗。两个计算芯片将连接到8个8-Hi HBM3e显存堆栈，总容量高达192GB。这一显存配置在目前的GPU市场中尚属罕见，AMD的Instinct MI300 GPU也仅提供了192GB的显存容量，但采用的是8个HBM3芯片。
而代号为B200的下一代Blackwell GPU更新则有望实现更高的显存容量，达到了288GB。据爆料，B200将采用12-Hi的封装方式，但并未透露具体的显存类型是HBM3e还是HBM4。
英伟达的这一动作无疑将进一步推动GPU市场的发展，特别是在高性能计算和深度学习领域。192GB和288GB的显存容量，对于需要大量数据处理和高速图形渲染的应用场景来说，无疑提供了更为强大的支持。
明日的GTC 2024主题演讲，无疑值得业界期待。英伟达是否会再次颠覆GPU市场，Blackwell GPU架构的具体性能如何，以及B100和B200的发布，都将为我们带来更多的惊喜。

**News Title:** **NVIDIA’s Blackwell GPU Leaked: B100 Models Feature 192GB HBM3e VRAM, B200 Models Reach 288GB**
Keywords: NVIDIA GTC, Blackwell GPU, HBM3e VRAM
**News Content:** # Next-Generation NVIDIA Blackwell GPU Architecture to be Unveiled: Highest VRAM Yet
According to reliable sources, NVIDIA, the globally renowned graphics processing unit (GPU) manufacturer, is set to release the next-generation Blackwell GPU architecture at the GTC 2024 tomorrow. The unveiling is expected to feature two new products: B100 and B200.
It is understood that the B100 GPU will be equipped with two chips based on TSMC’s advanced CoWoS-L packaging technology. This 2.5D packaging technique stacks chips together to enhance processing capabilities while saving space and reducing power consumption. The two computing chips will be connected to eight 8-Hi HBM3e VRAM stacks, with a total capacity of up to 192GB. This VRAM configuration is rare in the current GPU market. AMD’s Instinct MI300 GPU, which also offers 192GB of VRAM, uses eight HBM3 chips.
The next-generation Blackwell GPU update codenamed B200 is expected to achieve an even higher VRAM capacity of 288GB. Reports suggest that B200 will use a 12-Hi packaging method, but the specific VRAM type, whether HBM3e or HBM4, has not been disclosed.
NVIDIA’s move is bound to further propel the GPU market, particularly in the fields of high-performance computing and deep learning. The VRAM capacities of 192GB and 288GB provide significantly stronger support for applications that require extensive data processing and high-speed graphics rendering.
Tomorrow’s GTC 2024 keynote speech is undoubtedly an event to look forward to in the industry. Whether NVIDIA will once again disrupt the GPU market, the specific performance of the Blackwell GPU architecture, and the launch of B100 and B200 models, will all bring more surprises.
