Make sure to note that AMD64-(type of processor) 939-(the type of motherboard socket)/ AMD64 939 has real dual channel ram. Unlike Intel. AMD64 939 have a dual-channel 128Bit memory controller, thats built into the processor itself. Intel does not have this. For Intel dual channel ram, its utilized through the motherboard, just like the FSB. Witch makes it more latent for that reason. Intels dual channel ram is not desirable.
Since AMD64 939's have that special DDR controler, the data is processed faster. Another big differience between Intels arcitecture and AMD's. Is that AMD64 do not have FSB-FrontSide Bus. For all processors, FSB is built into the mobo. Again, thats more the processor has to do with the mobo, then itself. FSB and fake dual channel ram, is really just deficient.
But AMD64 on the other hand, dont have FSB. They have this special channel built into the processor called the HTT. Witch stands for HyperTransport Technology. This is basically the same unit as the FSB, but its built into the processor. Again, this is more desirable then FSB. Instead on data streaming from the mobo to the processor, the data is already at the processor. Not only is it built in the processor, it works alot faster then Intels FSB. Most of Intels FSB work at 800mhz, some new ones work at 1ghz, but these processors are extremely expensive. Other low-end Intels work at 533mhz and 233mhz. Overall, they work at 800mhz. AMD64 754 processors HTT works at 1.6ghz, then AMD64 939 processors work at 2.0ghz This is why AMD64 processors that are 2.2ghz and 2.4ghz can work alot better then Intels 3.4ghz-3.8ghz ect. AMD64 dont need 3.8ghz processors to work fast. They are more about arcitecture i think. Intel just throws these super high operating frequency chips out.
Dont confuse AMD64 HTT with Intels HT. Intels HT is HyperThreading. Overall i like AMD better, because of the way they are built, and perform with it. You never will see a AMD commercial. Intel as Nubius always says are marketing little fu2kZ! All they do is make brands sign special contracts, saying if you sell my product, you cant sell an AMD product. They constantly adverise, its pretty anonnying. You never see AMD doing this. Even Apple.
