How do you mean? Hyperthreading was turned off in the bios. That computer has two processors in it, each one has 8 physical cores, for a total of 16 physical cores.

That's a nice looking machine, Rodrigo. Those Xeons sure look nice.

Here are the results on the 4770K I got for Christmas. 4770K @ 4.3GHz, 2x8GB DDR3-2133 (CL11).

Definitely faster per core than my 3930K, but debatable for higher overall throughput. For prime95, WraithX's dual-2687W beats them both (best 8192K avg: 8.249ms vs. 10.442ms for 3930K, 13.072ms for 4770K). I'm using v28.1 as well which should give the 4770K even more advantage.

Thanks, danaj.

But if I read the numbers correctly, I see that each of your four cores can do about twice as much work as each of my eight cores, such that the total production would be about the same.

One has to question if the extra $$$ for the Xeon is truly worth it. In my case, it was hard to resist the allure of the brand. At least it's a laptop, which doesn't take up a lot of space, and that was a plus.
