惠普EliteBook 840 G9笔记本电脑评测。联想ThinkPad X1 Carbon的替代品 | Notebookcheck
与其他大多数商务笔记本不同，EliteBook 840/845 G9配备了英特尔vPro和AMD PRO选项，以吸引两边的粉丝。在最近审查了高端的Ryzen 9 PRO 6950HS AMD SKU之后，我们现在终于可以将其与高端的英特尔Core i7-1280P选项进行比较。

We were similarly impressed by the quality of the keyboard, which combines the excellent traits of quietness with a cushioned yet decisive action. It would be a pleasure to belt out a report on this machine. You can even play music in the background, with one of the better pairs of speakers in evidence here. This is a well-built laptop that may have taken our Labs Winner award if it wasn’t for the limited warranty and the question marks over which screen comes with which model.

HP EliteBook 840 G9 Review
Source: PC Mag EN→zh-CN
If you can live with a merely fine screen instead of a show-off OLED or 4K display, it's hard to fault HP's EliteBook 840 G9. This business laptop includes everything from 5G mobile broadband to a high-res, AI-enhanced conferencing camera, along with highly competitive performance and additional security. The only question in our minds is how HP can top it with the would-be EliteBook 1000 series, and whether it can earn our Editors' Choice award next time.
