I often see the title of the op amp specification that says high-speed op amp, so which parameter determines whether the op amp is high-speed? What does it mean? Is it related to the op amp bandwidth and slew rate?

In fact, this is defined by the manufacturer. For analog devices, the bandwidth is greater than 50MHz, which is generally the first element for choosing an op amp.

Look at the gain bandwidth, voltage gain X bandwidth, generally greater than 50MHz.

There are several parameters for an op amp. The gain bandwidth product, slew rate, etc. will determine whether it is a high-speed op amp. In fact, each company has a different definition, but the high-speed op amp must have a relatively high gain bandwidth product or Slew rate, you can read the specifications of the high-speed op amp to get the experience.
