Generally, most ThinkPads will come with integrated graphics, so don’t expect to play any AAA games natively or tackle intensive video-editing tasks on your ThinkPad.
The more important performance-related spec to pay attention to is the CPU. Most ThinkPads are powered by Intel processors, though you can find modern options with a Qualcomm Snapdragon X Elite processor as well. For solid performance, make sure the ThinkPad you’re looking to buy typically has a Geekbench 6 score of at least 10,000. The higher, the better.
