I find it very amusing when I get an email calling me an AMD zealot or saying that I am biased towards AMD. I have never considered myself "loyal" to either AMD or Intel, I simply go with whomever is faster.
Since I upgrade my motherboard and/or CPU pretty much every six months I have an interesting dilemma... Should I stick with an AMD setup and get a Thoroughbred processor or should I perhaps do something more radical and go with a Pentium 4? Here are a few of the things I contemplated while making my decision.
Performance:
Like many others I was caught up in the hype surrounding the "Thoroughbred" 0.13 micron AthlonXP based processor. I honestly thought it would bring AMD back into the spotlight and allow them to retake the performance crown from Intel. However, after playing with a Thoroughbred I was brought back down to reality. Why would a shrunken core (0.18 micron Palomino to 0.13 micron T-Bred) improve performance by leaps and bounds? It wouldn't since AMD didn't add any features to the core.
I was not a fan of Intel's Pentium 4 processor when it came out about 2 years ago. I didn't like the longer pipeline which resulted in lower IPC each MHz could handle. Because of this the P4 had a very rocky start, the 1.5 GHz Williamette (0.18 micron, 256 L2 cache) P4 could barely out perform Intel's own Pentium III 1 GHz!
Coming back to the present, now with lots of software supporting SSE2 and with the introduction of the Northwood (0.13 micron, 512KB L2 cache) Pentium 4, things are totally different. Clock for clock the P4 is still not as powerful as the Athlon but it's much closer. Also thanks to the new core's ability to clock high, Intel has retaken the performance crown away from AMD and doesn't look like they'll be losing it any time soon. I know AMD loyalists will scream this "Ya, Intel has the performance crown, but their CPU's run 700-800 MHz higher then AMD's! That's not fair, also you can overclock an Athlon to beat a P4." First, life's not fai r- that should be pretty obvious and so what if Intel CPU's need to run 700-800 MHz higher in order to beat an AthlonXP 2200+ (1.8 GHz)? Faster performance is faster performance and Intel's wearing the crown at the moment. AMD CPU's do overclock well and they're more fun to play with thanks to the ability to unlock the multiplier but you can also overclock P4's. Almost all 1.6A's out there can hit 2.4 GHz without even breaking a sweat, and many even can do 2.7 GHz!
With both processors overclocked, Intel still wins in terms of performance. Of course AMD's saving grace has always been price. AMD based systems and CPU's have always been a much better value, and they still are.
