Is the HP ZBook 8 G1i good for CAD?

Yes for 2D drafting and moderate 3D models. It runs ISV-certified software on a Core Ultra 7, but the integrated Arc graphics and 16 GB of RAM limit very large assemblies.

Can I upgrade the RAM and SSD?

HP workstations in this class typically allow RAM and storage upgrades through service access panels. Check the specific configuration's service manual before buying, since soldered memory would rule it out.

Does it have a dedicated graphics card?

It has integrated Intel Arc graphics rather than a separate GPU. That is fine for office work, design and light 3D, but not for GPU rendering or gaming at high settings.

Is the 16-inch screen good for outdoor use?

The large panel is comfortable indoors, but matte coatings and brightness vary by configuration. Check the display option's brightness rating if you work near windows or outside.

What comes in the box?

Expect the laptop, a power adapter and cable, and standard paperwork. A stylus, dock or mouse is not included unless the listing says so.

How does it compare with a consumer 16-inch laptop?

It adds Windows 11 Pro, business manageability and ISV certification, and usually a sturdier chassis. Consumer models often offer better graphics per dollar but less fleet support.
