Single/Dual/Quad CPU Info


In order to keep up to date with current CPU information, we have archived all previous info on this page to this LINK. Only the most current CPU info available will be displayed on this page. If you cannot find info on a specific CPU, please try the link above.

Before we begin, here are some technology terms associated with todays CPUs:

CPU Cache
is where the CPU stores recently used information by the system. The larger the cache the more information can be saved there before making room for new data. When a CPU needs to go and find information on something, its checks the cache to see it that information already exists. If it does, it simply pulls the info from that point. If not it must search elsewhere within the system to get the needed info. In essence a larger cache can increase your performance with certain types of programs.

Todays CPUs come in a wide variety of flavors, but still can be categorized as Single Core, Dual Core and Multi-Core. When we are talking about cores, we are referring to the physical processing chip located within the CPU itself. In general the more cores a CPU has the larger the processing power potential.

Both Intel® and AMD® produce single, dual, and quad core CPUs currently. A Single Core CPU means that there is only one logical processing core within the chip. Granted these single cores are far more advanced than previous generations, they only can process a single stream of information with one core at a time. These CPUs are the least effective when it comes to multi-tasking.

Intel's® HT (hyperthreading) technology help advance a single core CPU by allowing 2 threads of different information to be processed by a single core more efficiently, but the CPU still only had one core.

Dual Cores pick up where single cores left off, they have 2 logical cores and can dedicate one entire core to two separate incoming information streams simultaneously. Its almost like having two CPUs for the price of one.

Quad Cores pick up where dual cores left off, they have 4 logical cores and can dedicated one core up to four separate incoming information streams or any combination in between.
