I have used AMD K6-2 processors in my computers since March 1999. I love the performance of the Athlon. I have used computers with Intel 386 processors, Intel 486 processors, Intel Pentium processors, Cyrix PR266 processors, Intel Pentium 2 processors, Intel Celeron processors, Intel Pentium 3 processors, AMD K6-2 processors, Intel Pentium 4 processors, and AMD Athlon K7 processors.

Out of all the processors that I have tried and owned, I like my AMD Athlon 850Mhz Thunderbird processors the best. The Athlon 850Mhz T-bird is the fastest processor that I have owned to date. I have used a 1.0Ghz AMD Athlon T-bird processor that was someone else's. I still Like AMD Athlon processors. I am eager to try the AMD Athlon XP, AMD Athlon MP, AMD Athlon 64, and AMD Opteron processors.
I wanted to use that Athlon years ago but I didn't have a powerful enough power supply that I would be confident for the Athlon and I didn't have a cooling device for that Athlon. I think it was 2001 or 2002 when I last saw slot-A coolers for sale. They are rare now. Socket coolers are abundant because all new AMD and Intel processors are of the socket type.
I finally found a cooler and I got a 300 watt power supply to use in the system that I would put my Athlon in. Someone gave me a 300 watt power supply because it had some cosmetic blemishes and no one would buy it. He gave me the cooler because no one else had a use for it. I finally had to get some thermal grease or heatsink compound to bond between the heatsink and the processor and to transfer the heat well.
This Athlon performs very well, especialy since I have 16 times the amount of required memory to run the operating system, and I tried to optimize my system by carefully segregating the electrical and data parts as much as I could.
The wires that carry the electrical power cause EMI, Electromagnet Interference. It distorts the electrical field in the wires and circuits carrying the electricity that makes up the data transmission. The reason why the EMI slows down the system is because of the effects the EMI has on data integrity with the parity error checking.
You can learn how parity parity works by searching the internet. That is why I put search bars in my pages. I don't really care for the Intel processors because they got to the point when they recycle too much technology in favor of marketing sales advantages.
Sure each one that they produce is faster than the previous, but in way ways do they make this happen is the point. Intel hasn't really impressed me in the last few years. They do a little processor core technology improvment compared to the amount of speed that they gain by simply increasing the operating frqequency.
It appears that increasing the operating frequency or how often something is done, is about the cheapest way to increase speed and bandwidth. It looks like Intel is doing a lot of that. I keep hearing about how the Pentium 3 had a stronger processing core than the Pentium 4.
That is what Intel does, does some cheap modification to gain ust a little performance and markets it for an arm and a leg's worth of money to their loyal unsuspecting customers. That is why I don't like Intel, their ethics, practices, and marketing.
