The 380's comes with Dual Core Pentium type processors but only ONE dual core pentium type processor. This gives you (2) Two Cores total in the machine.
The only dual core processors you can get in a 380 are the
Pentium D 820, 830, 840 840EE, 920, 930, 940, 950 and 955EE .
On all of the processors except the 840EE and 955EE, hyperthreading IS NOT supported. The most expensive processors offered in the 380 - the Pentium D 840EE and 955EE support hyperthreading which gives you a total of (4) logical processors. The 800 Series dual cores offered on the 380 also only have 1MB of L2 cache per core for a total of 2MB of L2 cache. The 900 series dual cores have 2MB of L2 cache per core for a total of 4MB L2 Cache
The Precision 670 takes (2) Dual Core Xeon Processors and they support hyperthreading (A total of 4 Cores and 64-bit processors to boot) Enable hyperthreading and you have a total of 8 logical processors. When viewed from the Performance Tab in Windows Task manager you will see 8 separate processors there. On the Dual Core Xeons you have 2MB of L2 Cache per core for a total 8MB of L2 cache
On both machines you can run Windows XP x64 edition and the 4GB memory limit is a thing of the past. I am not sure if Dell sells the Precision 380 configured with Windows XP x64 but you could surely add it yourself. I think that Microsoft in some cases even allows a free upgrade from the 32-bit edition to the 64-bit edition but you only are allow to have one or the other. I intially started out with the 32-Bit version of XP Professional on one of the P670 boxes and then switched over to the 64-bit version (Windows XP x64 Edition) There is a HUGE difference in the way this box performs - even with 32-bit applications. If you are running processors that will support Windows XP x64 (and you have drivers for all of your other items) the OS is really the only way to go - it is that much of a difference. I imagine Vista will be the same way.
Overall - the Precision 670 is still steps above the Precision 380.
