XP Home vs. XP Pro on Dual Cores

[TC]

I had a couple people asking me to check this out, so I benched my new dual core 820 system under xp home and pro. The results are nearly identical. While this certainly isn't a full test battery, it does appear that home is at least fairly capable of handling dual cores. From top down the home results, followed by pro:

i would think so, considerig the only major diff between home and pro is some adminitrative secuity features in PRO.

and pro is for multi cpu right?

[Know Nuttin]

results as expected. XP Home supports dual core, not dual CPU.

Very nice. now overclock that sucka!

Did you try it with Hyperthreading enabled?

I don't think it supports dual+HT... but I am most likely wrong.

[dustybyrd]

it's my understanding that xphome is dual core capable (because microsoft agreed to 1 license per "physical" cpu)...even though i thought xphome was not capable of HT (not sure about this one)

iirc, the only dual core intel cpu's that will support HT will be the Extreme edition ones and the new dual core xeons...

also, only xp-pro will support 4 cpus (2 logical and 2 virtual) with the HT, extreme edition dual cores and xeon dual cores

[Mr.Guvernment]

ahh yes - i forgot about the licensing as well :d

I see there's a bug in Sandra where it states my cpu has HT. Well it probably does and it's just disabled.

Got my water cooling. It boots at 4.2GHz but acts a little flaky. Looks to be fairly solid at 4GHz 1.45 volts 52C under load. Nice chip:

there are a good number more differences than just that :) most of which are network and hardware related (mostly network)

Only EEs will have HT.

Home supports HT.

Home does support HT
