can you tell me more about the "CPU Bus/Core ratio"?

Question

Now I must say I'm quite intelligible when it comes to PCs but when you get into these much much deeper aspects of hardware my knowledge begins to slip...

Anyway, this is my processor and all of its Super-Geek stats as provided by Intel:

http://processorfinder.intel.com/details.aspx?sSpec=SLA45#

Now I could give a Toss about the things like the Core Stepping or the Voltage and etc. but the one that bothers me is the Bus/Core Ratio.

The Intel pop-up that tries to explain it seems vague-ish, and wikipedia only says its the ratio between FSBus speed and Clock Speed.....

But if that were the case my value shouldnt be 10 should it? In my math it came out as a ratio of 2.5 (or 5 if you consider each core as 2.0ghz...)

Heres what I did anyway:

(2.0x10^9) / (800x10^6) which is the scientific notation for 2Ghz/800Mhz. My answer is 2.5.

SO my question is:

-Why is my ratio 10?
-Does each core run at 2.0ghz or 1.0Ghz?

Answer 1

Intel FSBs are quad pumped, meaning they send 4 pieces of data every clock cycle. When the FSB speed is listed as 800Mhz, they have already factored the quad pumping in, and are giving you the effective speed. The actual speed of the bus is 200Mhz. If you take 200Mhz times the 10 multiplier, that will give you the 2Ghz speed.

Answer 2

I wouldn't consider it to be self absorbed for somebody to be excited on their most likely favorite day of the year. So, I guess no. If the conversation went like this, "Happy Me Day!" "Oh, It's my Birthday too!" "Who cares? *walks off*" Then I can see how that would make the person a narcissist, but otherwise... Think about it ☆
