CPU help?

by boyien03 / January 30, 2009 6:44 AM PST

Is Duo Core 2.8 GHz mean that it has two CPU running at 2.8 GHz each, so it is like 5.6 GHz total? What about Quad and i7 CPU?

Two processors running at 2.8, but they're separate, no adding is done.

It's the same clock across both

Without getting into techno speak to much. No, Dual core processors do not double the operating frequency. Dual core is not technically 2 CPU's. It's one physical plus 1 logical.(this will help explain quad in a moment). The Quad core such as q6600 series operates under the same clock (frequency or "Ghz") across all of it's cores as well. It's technically 2 dual cores with a total of 2 physical and 2 logical cores. Ok, I went a little techno on you. To put it simply, no you do not get double your fun. The clock speed is set across all CPU's and is the same for all processors out there. If you want to beef your CPU, you could look into overclocking. But as a new overclocker expect you will destroy your first set-up. (a learning experience).

no, dual core has two *physical* processing units

Intel describes it as this:
Dual-Core Processing, combines two independent processor cores in one physical package. Processors run at the same frequency and share up to 6MB of L2 cache and up to 1333 MHZ Front Side Bus for truly parallel computing

hyper-threading adds a "logical" processor making it appear as if 2x processors are available. core i7 are hyper-threading enabled quad-cores which appear to have 8 processors.
