我发现2015年的旧笔记本电脑具有以下规格。
- 型号：Inspiron 5558（CPU：i5-5200u，GPU：GeForce 920mx）
- 内存：8GB（DDR3）
- 储存：HDD（1TB 5200RPM）
- 操作系统：Windows 10 / Ubuntu 20.04（Dual boot）
More System Information
It's extremely slow for the specs it has. Day to day use is nearly impossible. I tried running geekbench 5 to see how it compares. Geek Bench Results. In short, I got single-core: 67 and multi-core: 216 compared to (700, 1500) what others got on the same model. I also checked CPU usage(100% usage) while running geekbench. I also ran ubuntu's disk benchmark and the results were normal as it gave me a read speed of 108MB/s on this HDD. Geekbench results on ubuntu were also very similar. Geekbench OpenCL(920mx) gave me a score of 3000 which is also normal considering the old GPU and 920mx. There are no signs of overheating.
我不明白到底哪里出了问题？
