What technology amd are using? why they are good in games?

All other components considered. Some of the things that give AMD the edge include. 0. Lower CPU power requirement. 1. Lower heat dissipation (cooler). 2. Higher computation numbers per cycle. 3. Intergrated memory controller. 4. Friendly to overclocking. 5. Usually cheaper to build. Since you are most likely looking at a K8 upgrade, you should go over its architecture as well.

"3. Intergrated memory controller." That's the key reason why. Intel doesn't have an intergrated memory controller. The frontside bus connects the CPU to the main memory in a system. AMD's integrated memory controller is on the chip which reduces system latency, or the amount of time it takes for data to move from one component to another. So in other words Intels memory controller is slower because it has to go outof the processor to the FSB and back again. AMD's memory controller doesn't do that since it's intergrated into the chip.

One more thing to note why Intel has stayed away from intergrated memory controllers for this long. Anyone remember Intels Timna processor? You prob dont, because it was never launched. It was suppose to launch back in mid 2001 and it did feature an integrated memory controller, but it was locked into Rambus' RDRAM (Rambus dynamic RAM) memory technology, which was too expensive for most users. The chip never saw the light of day, partly because RDRAM never entered the mainstream and partly because Timna's chip set was delayed due to several manufacturing flaws.
