How can a notebook at 667MHz be a Santa Rosa?

The most obvious striking feature of the Santa Rosa platform is its 800MHz FSB. If so, is an Inspiron 1420 and Inspiron 1520 a Santa Rosa laptop, given that it has 667MHz FSB?
Here's the link of the review on this very website that claims those above mentioned models to be Santa Rosa: click here

PS: I'm totally aware of other features that go into a Santa Rosa, but i'm focusing solely on FSB here.

 

667 FSB is not a requirement.

 

The 2nd feature states: " .... 800 MT/s front side bus with Dynamic Front Side Bus Switching to save power during low utilization"
What about that?

 

from what i see, those notebooks do have an 800mhz fsb.

 

I'm an idiot, didn't see that.

Could just be a typo on Dell's website.

 

There are some budget Santa Rosa processors (T5x50) that have 667FSB. The T7100 and up have 800.

 

budget or not, how can it be called a Santa Rosa when its obviously missing a key feature?

 

It's the motherboard and wireless chipset that make it Santa Rosa, and the CPUs are the same except they're slower with a slower FSB, and may have less cache. It's just a method to cut performance without killing off the marketability (clock speed) of budget CPUs.

 

Santa Rosa is just an Intel codename for the platform, the major OEM's don't advertise their notebooks as Sonoma, Napa or Santa Rosa notebooks. It's just an easy way to differentiate between the generations for people more in the know.

If you want to nitpick, any notebook without the appropriate Intel wireless card can't be called by the codenames either.

And in this case it depends on the CPU installed, the chipset simply sets the FSB accordingly. Blame Intel if you want for releasing lower end chips.

 

They are not missing the ability to run at 800 FSB. That has to do with the chipset and not the CPU. So you could install a 7100 and it would run at 800 FSB.
