That's because the SPARC M7 has a significantly larger die size. It's a very specialized chip that costs an order of magnitude more than consumer Intel hardware and is manufactured with tech a generation behind. If Intel were to manufacture a chip as big as that, it would have 20-30 billion transistors.
