Nvidia's GB10 Superchip Shows Modest Performance in Early Benchmarks, Trails Apple M3 and Qualcomm Snapdragon X Elite
Nvidia's GB10 Superchip, designed for compact AI workstations, has received its first benchmark results in Geekbench 6. Although the processor is intended for high-performance AI applications, its compute capabilities appear less impressive compared to those of Apple’s M3 and Qualcomm’s Snapdragon X Elite. These results are particularly notable as they come from a pre-release version running on Windows 11 Enterprise Insider Preview. The GB10 Superchip is a system-in-package (SiP) that combines a Grace CPU with 10 high-performance Arm Cortex-X925 cores (clocked up to 3.90 GHz) and 10 energy-efficient Cortex-A725 cores, along with a Blackwell GPU capable of delivering 1 PetaFLOPS of FP4 compute performance for AI tasks. It supports 128 GB of unified LPDDR5X memory with a 273 GB/s bandwidth, similar to Apple's M4 Pro in memory capabilities. In single-core performance, the GB10 achieved a score of 2,960, placing it nearly on par with Qualcomm’s Snapdragon X Elite and just below Apple’s M3. This score indicates that the Cortex-X925 cores deliver fairly strong performance, though it lags behind higher-end offerings like Apple’s M4, AMD’s Ryzen 9 9950X, and Intel’s Core Ultra 9 285K in terms of peak IPC performance. Multi-core performance, however, is where the GB10 shows more significant limitations. Despite its 20-core configuration, the chip scored 10,682 points in Geekbench 6, falling behind the 8-core Apple M3, the 10-core Apple M4, and the 12-core Snapdragon X Elite. The GB10 is even more significantly outperformed by high-end CPUs like the Ryzen 9 9950X, which scores over 25,000 points. Industry experts suggest that the modest results might be attributed to the pre-release status of the hardware and the early version of the operating system. Additionally, the Cortex-A725 efficiency cores may not be contributing effectively to the overall score, possibly due to scheduling issues that could be resolved with updates to Windows 11 or Nvidia’s microcode. Alternatively, the design of the GB10 may prioritize power efficiency and die area, with the CPU handling secondary tasks like scheduling and data preprocessing, while the Blackwell GPU takes the lead in compute-intensive AI workloads. Nvidia's broader strategy includes extending its reach into client PC processors. Rumors indicate that the company will announce its N1 and N1X processors for desktop and laptop PCs during Computex later this month. The N1 and N1X are expected to have a similar CPU configuration to the GB10, suggesting that their compute performance will be comparable. However, the initial benchmark results raise questions about whether these chips will be competitive in the consumer market. Despite these limitations, Nvidia’s focus on AI-centric workloads is clear. While the GB10 may not dominate traditional CPU benchmarks, it is designed to excel in specific AI scenarios where the GPU plays a crucial role. Real-world performance in AI tasks could still be highly competitive, as Geekbench is an artificial benchmark and may not fully represent the chip’s strengths in practical use cases. Industry Evaluation and Company Profiles The benchmark results of the GB10 Superchip have drawn mixed reactions from industry insiders. Some argue that the performance metrics may not accurately reflect the chip's intended use case in AI workstations, where the GPU’s capabilities are often more critical. Others suggest that Nvidia’s emphasis on thermal and power efficiency in compact platforms is a strategic choice that might benefit users focused on energy consumption and form factor. Nvidia, founded in 1993, is a multinational technology company widely recognized for its graphics processing units (GPUs) and AI computing solutions. The company has been at the forefront of developing hardware and software for accelerating AI, deep learning, and inferencing tasks. This investment in the GB10 Superchip aligns with Nvidia's ongoing efforts to diversify its product portfolio and cater to the growing demand for specialized AI hardware. Apple, meanwhile, continues to set a high bar for performance with its M-series chips, which are designed for both mobile and desktop devices. The M3 and M4 processors, released in 2023 and 2024, respectively, highlight Apple’s commitment to leading in both traditional computing and AI applications. Qualcomm, a leading provider of wireless technologies, has also been expanding its presence in the AI market. The Snapdragon X Elite, announced in 2024, aims to deliver top-tier performance for mobile and embedded devices, making it a formidable competitor to Nvidia’s GB10 in certain segments. In conclusion, while the initial benchmark results for Nvidia's GB10 Superchip are modest, they may not tell the whole story. The chip’s performance in real-world AI applications and its potential improvements through software and firmware updates will be crucial indicators of its success in the market.
