The question on everyone's mind: Can NVIDIA's GB10, designed for AI dominance, actually hold its own in traditional CPU tasks against AMD's impressive Ryzen AI Max+ 'Strix Halo'? We're diving deep to find out!
At Phoronix, we've been putting the Dell Pro Max GB10 (check out the preview here: https://www.phoronix.com/review/dell-pro-max-gb10-preview) through its paces, primarily focusing on its AI prowess, thanks to its Blackwell GPU (as detailed here: https://www.phoronix.com/review/dell-pro-max-gb10-llama-cpp). After all, the GB10 superchip was explicitly engineered to crush AI workloads. But here's where it gets controversial... many of you, our dedicated Phoronix readers, have been clamoring to know: what about the GB10's raw CPU performance in everyday Linux tasks?
So, to satisfy that curiosity, we're presenting a detailed Linux benchmark showdown, specifically concentrating on CPU performance. We're pitting the Dell Pro Max GB10 against the Framework Desktop, powered by the AMD Ryzen AI Max+ 395 'Strix Halo' – a formidable opponent in its own right.
The NVIDIA GB10 superchip is a fascinating beast. Under the hood, it boasts 20 Arm cores, a combination of ten high-performance Cortex-X925 cores and ten energy-efficient Cortex-A725 cores. These cores work in tandem with a generous 128GB of LPDDR5x memory, providing a respectable amount of CPU horsepower in addition to the Blackwell GPU's capabilities. And this is the part most people miss... the sheer flexibility that this architecture could unlock, if properly leveraged.
To rigorously assess the CPU performance of the GB10's Arm cores, we subjected both systems to a battery of Linux CPU benchmarks. This allowed us to directly compare the Dell Pro Max GB10's CPU capabilities to those of the Framework Desktop running the AMD Ryzen AI Max+ 395 Strix Halo SoC. Think of it as a head-to-head competition to see which chip reigns supreme in general-purpose computing.
Now, for a crucial caveat: While AMD and Intel SoCs conveniently expose CPU power consumption data through Linux's PowerCap/RAPL interfaces, the NVIDIA GB10 remained tight-lipped. It didn't provide any CPU power metrics through these standard interfaces. Consequently, for power analysis, we had to rely on the total AC system power consumption for both the Dell Pro Max GB10 and the Framework Desktop. To accurately measure this, we used a WattsUp Pro power monitor to track AC power consumption in real-time for both systems, allowing us to calculate and compare performance-per-Watt. Is this a fair comparison? Some might argue that isolating CPU power draw is essential for a true apples-to-apples comparison. What do you think?
Both systems were running Ubuntu 24.04.3 LTS (a noteworthy detail: NVIDIA DGX OS is currently based on Ubuntu 24.04.3 LTS), utilizing the Linux 6.14 kernel and the GCC 13.3 compiler. We extend our sincere gratitude to Dell for providing the Pro Max GB10 for testing at Phoronix, and to Framework Computer for supplying the review sample of the Strix Halo Framework Desktop. Without their support, this in-depth comparison wouldn't have been possible.
So, the burning question remains: Did NVIDIA's AI-focused GB10 surprise us with its CPU performance? Or did AMD's Ryzen AI Max+ 'Strix Halo' maintain its lead in traditional computing tasks? Stay tuned for the benchmark results and our detailed analysis! What are your predictions? Do you think NVIDIA can compete with AMD in a non-AI focused task? Let us know in the comments!
