Intel Core 2 Duo 2.2 GHz Processor Review

Core 2 Duo Processor by Intel, an engineering marvel.

When Intel went to the 45 nana-micron* technology they opened the door for faster, smaller, lower power consumption processors.

Core 2 means the second in a series of new core processors, the first was introduced with the Pentium 4 D. Duo means two processors on the same PCB that used to have only one processor. Quad means four processors on the same PCB. (PCB means Printed Circuit Board). Now we are getting twice or four times the bang for our hard earned buck! Hold on to yer hat I have read where Intel is investigating the possibilities for eight and sixteen processors on a single PCB.

I upgraded my computer from a Pentium 4 motherboard to a Core 2 supported motherboard. I chose the E4500 processor, Core 2 Duo that runs at 2.2 GHz. I chose the 2.2 GHz processor because it was fairly fast and cheaper than the higher end Duo processors. I did this with the intent of going to a Quad processor in the near future and did not want to spend the same amount of money twice. Over time the cost of the Quad processors will drop and be more affordable for the ordinary user, at this time they are well over five hundred dollars.

With a built in cache (memory that is incorporated into the processor) each processor has one meg of ram to fetch instructions from. Older processors normally had 256k or 512K (Kilobytes) this is a vast improvement making a
single processor as fast as an older Pentium 4 processor running at 3 GHz, add another processor and you have twice the through put.

Another advantage to the new Core 2 Duo and Quad processors is the ability to increase the voltage of the processor with out burning out your processors. This is a big boon for those that like to push their systems to the max. (I am overclocking my system from 2.2 to 2.5 GHz, this may not seem like much but that is like overclocking a P4 3.0 GHz to 4 GHz!)

With the features of the motherboard (see my review of the ASUS P5K motherboard) the processors fly's!

Quote Intel's web page:

Intel® Advanced Smart Cache, providing a higher-performance, more efficient cache subsystem. Optimized for multi-core and dual-core processors.
Intel® Smart Memory Access, improving system performance by optimizing the use of the available data bandwidth.
Intel® Wide Dynamic Execution, enabling delivery of more instructions per clock cycle to improve execution time and energy efficiency.
Intel® HD Boost utilizing new SSE4 instructions for even better multimedia performance.

These improvements make the new Core 2 processors the 'King of the Hill'

*Nana-micron is very small, like 1/1000th the with of a human hair. This allows the electrons to flow faster and at a lower voltage, thus the processor runs cooler.
