You get 2 cores, but they do not support multiple hyperthreads per core. I'm typing this on a new D 820 system, and there are 2 cores, but that's it. See http://www.intel.com/products/processor/pentium_D/index.htm for more info. As for overall performance, it's a bit of apples to oranges. My other system (hyperthreaded) had a faster clock speed, but the 820 has a larger cache and somewhat faster data paths.

Hyperthreading needs to be enabled in the BIOS for FreeBSD to see the second CPU. It appears the CPU presents itself as a hyperthreaded CPU with two "logical" CPUs - each "logical" CPU actually corresponding to a CPU core. I'll attach the dmesg output. I installed "vanilla" 5.4 and then had to tweak a few driver source files to get the motherboard LAN, the ICH7 in-built audio, the ICH7 ehci USB and the ICH7 SMB controller recognised.

Showing a second CPU on a dual-core die as a hyper-threaded seems to avoid this problem. The question is now: AMD does not have HT, do they also show the second CPU as a logical one (from the point of view of the BIOS)?

I presume intel did something similar. -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.
