Yes, looks like a pretty bad case although there are plenty of healthy leaves. Try picking off all affected leaves and see how it goes. If you decide to replace it, I can recommend Avalon Pride which is very resistant. A few leaves do become affected on mine, but only a dozen or so each year and I just remove them as soon as I see them. It's a good cropper of full-size peaches. Mine came on Mont Clare rootstock and is now about 2m x 2m after 8 years, so relatively small for a peach tree.
