Bottom line is years ago, Intel marketed their products well. They were practically in every machine that was built. Now, the tables have turned (almost 50% anyway) and AMD is gaining ground on Intel. From a marketing standpoint, Intel is still very strong because they can meet supply and demand largely due to thier multiple factories and support. AMD does not have this luxury.
I for one have said many times in these forums, that a decision to buy a processor should not solely be based in reviews by others, biased or unbiased testing and benchmarks or otherwise. They should be based on real world testing and every day use.
I have the luxury of building multiple machines for my own use, testing and comparing. There is simply nothing better than being able to take an Intel machine and compare it to an AMD machine. I for one can see differences between the two but for the most part, its very subtle. My Intel prescott machine performs just as well if not better than my X2-3800 machine in most areas. As far as heat index goes, there is none. I'll post a link to show my prescott specs including temps.
Toms hardware as well as others have reported that AMD always perform better in gaming and other areas. Those benchmarks don't mean anything to me and apparently to alot of others as I've read in several forums that they seem biased. There are simply too many factors involved such as the boards chipset. You can have the fastest processor in the world, if the chipset can't move the info from point A to point B as fast, the processor is rendered useless IMO. Yes there are processor specific applications but in some way or another, the board is involved. We also have to remember that in those tests even the ones conducted by Toms, that AMD did not win every category.
In conclusion AMD and Intel both make very good processors. Its all about choices. AMD is gaining ground and that makes me happy because the testing is more equal with the machines on my bench. All I can say is, to each his or her own. As far as Intel, they're not down and out, they're just preparing to take the ball back from AMD.
