About MacBook pro

The Intel UHD graphics 630 1536MB is built into the CPU, and is called "intergrated graphics." It is used for "soft" tasks and useful when on battery power because it consumes less power.

AMD Radeon Pro 5500MB graphics is separate from the CPU so is called "discrete graphics." It is much more powerful than integrated gfx for tasks demanding high resolution and/or redraw speed. If used on battery power it will drain the battery faster.

One typically uses discrete graphics when on wall power and integrated graphics when on battery power. The computer can automatically change which gfx set it uses when you change power sources.
