It kind of is when you're talking about desktop cpu's and gpu's. There are exceptions of course (r9 290 about same price as 770 gtx but stronger, 8320 cheaper than some i3's, but stronger in rendering - i3's still kill 9590 in single core performance -), but in general it's true. AMD does not compete with intel in the high end, therefore their top of the line products are cheaper than intels. In general, you get what you pay for.
