The answer is as follows: Generally speaking, the graphics chip of a laptop computer cannot be upgraded. Unlike desktops, laptop graphics chips are often soldered directly to the motherboard and tightly integrated with other hardware components, making them difficult to replace or upgrade.
However, some high-end gaming books or workstation laptops may have upgradeable graphics card options. These computers are usually equipped with MXM (Mobile module) graphics card slots, allowing users to change the graphics chip within a certain range. However, this upgradeable graphics card option is usually only available for specific models and requires a certain amount of technical knowledge and experience on the part of the user.
In general, most laptop graphics chips cannot be upgraded, so consider the required performance and features when buying, so as not to be unable to meet the demand later.
