During its latest FY2024 earnings call, NVIDIA's CEO Jensen Huang gave a few predictions about future products. The upcoming Blackwell B300 series, codenamed "Blackwell Ultra," is scheduled for release in the second half of 2025. It will feature significant performance enhancements over the B200 series. These GPUs will incorporate eight stacks of 12-Hi HBM3E memory, providing up to 288 GB of onboard memory, paired with the Mellanox Spectrum Ultra X800 Ethernet switch, which offers 512 ports. Earlier rumors suggested that this is a 1,400 W TBP chip, meaing that NVIDIA is packing a lot of compute in there. There is a potential 50% performance increase compared to current-generation products. However, NVIDIA has not officially confirmed these figures, but rough estimates of core count and memory bandwidth increase can make it happen.

Looking beyond Blackwell, NVIDIA is preparing to unveil its next-generation "Rubin" architecture, which promises to deliver what Huang described as a "big, big, huge step up" in AI compute capabilities. The Rubin platform, targeted for 2026, will integrate eight stacks of HBM4(E) memory, "Vera" CPUs, NVLink 6 switches delivering 3600 GB/s bandwidth, CX9 network cards supporting 1600 Gb/s, and X1600 switches—creating a comprehensive ecosystem for advanced AI workloads. More surprisingly, Huang indicated that NVIDIA will discuss post-Rubin developments at the upcoming GPU Technology Conference in March. This could include details on Rubin Ultra, projected for 2027, which may incorporate 12 stacks of HBM4E using 5.5-reticle-size CoWoS interposers and 100 mm × 100 mm TSMC substrates, representing another significant architectural leap forward in the company's accelerating AI infrastructure roadmap. While these may seem distant, NVIDIA is battling supply chain constraints to deliver these GPUs to its customers due to the massive demand for its solutions.

NVIDIA kicks off the 2025 International CES with a bang. The company is expected to debut its new GeForce "Blackwell" RTX 5000 generation of gaming graphics cards. It is also expected to launch new technology, such as neural rendering, and DLSS 4. The company is also expected to highlight a new piece of silicon for Windows on Arm laptops, showcase the next in its Drive PX FSD hardware, and probably even talk about its next-generation "Blackwell Ultra" AI GPU, and if we're lucky, even namedrop "Rubin." Join us, as we liveblog CEO Jensen Huang's keynote address.02:22 UTC: The show is finally underway!

NVIDIA "Blackwell" series is barely out with B100, B200, and GB200 chips shipping to OEMs and hyperscalers, but the company is already setting in its upgraded "Blackwell Ultra" plans with its upcoming GB300 AI server. According to UDN, the next generation NVIDIA system will be powered by the B300 GPU chip, operating at 1400 W and delivering a remarkable 1.5x improvement in FP4 performance per card compared to its B200 predecessor. One of the most notable upgrades is the memory configuration, with each GPU now sporting 288 GB of HBM3e memory, a substantial increase from the previous 192 GB of GB200. The new design implements a 12-layer stack architecture, advancing from the GB200's 8-layer configuration. The system's cooling infrastructure has been completely reimagined, incorporating advanced water cooling plates and enhanced quick disconnects in the liquid cooling system.

Networking capabilities have also seen a substantial upgrade, with the implementation of ConnectX 8 network cards replacing the previous ConnectX 7 generation, while optical modules have been upgraded from 800G to 1.6T, ensuring faster data transmission. Regarding power management and reliability, the GB300 NVL72 cabinet will standardize capacitor tray implementation, with an optional Battery Backup Unit (BBU) system. Each BBU module costs approximately $300 to manufacture, with a complete GB300 system's BBU configuration totaling around $1,500. The system's supercapacitor requirements are equally substantial, with each NVL72 rack requiring over 300 units, priced between $20-25 per unit during production due to its high-power nature. The GB300, carrying Grace CPU and Blackwell Ultra GPU, also introduces the implementation of LPCAMM on its computing boards, indicating that the LPCAMM memory standard is about to take over servers, not just laptops and desktops. We have to wait for the official launch before seeing LPCAMM memory configurations.
