Apple M5 Ultra Scores Big GPU Gains in Leaked Geekbench Benchmark

TechPowerUp • September 18, 2026 • technology

Key Points:

Leaked Geekbench benchmarks show significant GPU performance gains for Apple's M5 Ultra chip, though comparisons with NVIDIA GPUs vary depending on the test category (CUDA, OpenCL, Vulkan).
Some users express skepticism about Geekbench's accuracy and relevance for real-world hardware comparisons, suggesting synthetic benchmarks can be optimized and may not reflect actual performance.
Critics highlight that while Apple scores well on Geekbench, real application and gaming performance often tell a different story, especially compared to high-end NVIDIA GPUs like the RTX 4090.
There is interest in Apple's Mac Studio machines for large language model (LLM) workloads, with reports that chaining multiple units via Thunderbolt can significantly boost performance.
Overall, commenters recommend waiting for comprehensive, real-world tests before drawing conclusions about the M5 Ultra's GPU capabilities.
