Intel CPUs are decidedly better value when multicore performance is a concern. At the top end they trade blows.
If your workload is pointer-chasing intel's new CPUs aren't great though, and the X3D chips are possibly a good pick (if the workload fits in cache) which is why they get a lot of hype from reviewers who benchmark games and judge the score 90% based on that performance.
