在即将于明日举行的2024年全球GPU技术大会（GTC）主题演讲中，英伟达预计将揭开其新一代GPU架构——Blackwell的神秘面纱。据业内爆料网站XpeaGPU透露，这款备受期待的B100 GPU将搭载先进的技术，以满足高性能计算的需求。
B100 GPU将采用台积电的CoWoS-L（晶圆基片芯片）2.5D封装技术，这种技术通过将芯片堆叠，能够在提高处理能力的同时，节省空间并降低能耗。据称，B100将配备两个计算芯片，与8个8-Hi HBM3e高带宽显存堆栈相连，总显存容量将达到192GB。这一配置与AMD的Instinct MI300 GPU相当，后者也拥有192GB的显存，但使用的是8个HBM3芯片。
此外，XpeaGPU还暗示了一个更高级的版本，代号为B200的Blackwell GPU更新。据爆料，B200将通过12-Hi设计实现更高的显存容量，达到288GB。尽管未明确指出是HBM3e还是HBM4技术，但这一升级无疑将为数据中心和专业应用提供更强大的计算能力。英伟达CEO黄仁勋的明日演讲将为这些爆料提供官方的确认和详细的解读，敬请期待。

**News Title:** “NVIDIA GTC 2024 Preview: Jensen Huang Expected to Unveil Blackwell GPU with B100 Offering up to 192GB VRAM”
**Keywords:** NVIDIA GPU, Blackwell, HBM3e VRAM
**News Content:** During the keynote address at the upcoming 2024 Global GPU Technology Conference (GTC) tomorrow, NVIDIA is anticipated to lift the curtain on its next-generation GPU architecture, Blackwell. According to insider reports from XpeaGPU, the eagerly awaited B100 GPU is set to feature cutting-edge technology to cater to high-performance computing requirements.
The B100 GPU will employ TSMC’s CoWoS-L (Chip-on-Wafer-on-Substrate) 2.5D packaging technology, which, by stacking chips, enhances processing capabilities while conserving space and reducing power consumption. It is rumored that the B100 will incorporate two compute chips interconnected with eight 8-Hi HBM3e High Bandwidth Memory (HBM) stacks, providing a total VRAM capacity of 192GB. This matches AMD’s Instinct MI300 GPU, which also boasts 192GB VRAM but utilizes eight HBM3 chips.
Furthermore, XpeaGPU hints at a higher-end variant, the Blackwell GPU update codenamed B200. Leaks suggest that the B200 will achieve an increased VRAM capacity of 288GB through a 12-Hi design. While it is unclear whether this upgrade employs HBM3e or HBM4 technology, it undoubtedly promises a significant boost in computational power for data centers and professional applications. NVIDIA CEO Jensen Huang’s presentation tomorrow will provide official confirmation and in-depth insights into these revelations. Stay tuned.
