UnverifiedIn a complete AI application system, GPU inference typically accounts for only 30%–40% of total compute, with the remaining 60%–70% of the compute load borne by the CPU.71% similarUnverified许多推理服务的GPU利用率不足30%，通过VGPU技术可将利用率提升至70%以上69% similarUnverifiedDuring testing, only 1 of the 4 GPUs reached a utilization rate of approximately 10%–13%, while the rest were nearly idle, and CPU usage was as high as approximately 50%.69% similarUnverifiedWithout a sufficiently optimized software stack, actual GPU utilization often reaches only 30–50% of the theoretical peak.68% similarUnverifiedFor tasks such as CRUD development, API integration, and style adjustments—which account for more than 70% of daily work—the output quality gap between mid-range models and top-tier models is less than 10%.67% similar
