AMD were getting peeved because Intel kept claiming that faster processors (measured in MHZ) are the be all and end all of everything, and using that as a selling point of the P4..
what they didn't tell you, is that even a PIII of an equiv clock speed is faster then a P4, because Intel didn't want it made obvious, they didn't release a P4 at 1gig, or 1.2gig, and they didn't make a PIII at 1.4gig.. but they did make a PIII 1.2, and that 1.2 is faster then a 1.6gig P4.. which is why we are not likely to see more PIII's.. I have had an AMD XP1800+ running in a room with an ambient temp of around 35degrees Celcious.. and it runs just fine. (uptime of 4 months currently.) it is a fairly loaded machine, runs everything from apache, alot of perl cgi, firewall's, mail server, mail virus scanning.. and heaps of other stuff, and it powers along.. Once concession I made was to put a 7500 rpm coper base heat sink on the CPU, and its been fine ever since.. (runs rather cool actually) and it cost me only about 15USD to buy the fan. Testing shows, that the 1900XP, is just about the same speed as a 2.2 gig Northwood P4 (the latest one.) even though the AMD is only running at 1600mhz. and AMD just released the 2000+, which would obviously be faster again.. There are a few things to keep in mind.. the P4, is almost a glorified seriously overclocked 486 in many cases.,, it relies on brut mhz to achieve its speed, it has a extremely simplified architecture, which is why it reaches hight MHZ so much easier then the AMD and the PIII. also, you might keep this in mind as well.. The difference between a P4 2gig and a 2.2gig is around only 5%, even though its 200mhz faster.. the differnce between a AMD XP1600+ and the 1800+ is close to 15% and if you look at the actual clock speed, its alot less then 200mhz difference between the two.. so the higher up the clockspeed the AMD's go, the further ahead they will get on the P4... I use the XP1800+ on a MSI KT266A chipset motherboard with DDR SDRAM and it was the best purchase I have ever made.. (I will be upgrading it to the XP2000+ soon, (unless they release a faster one, in which case I will get that.) Go the AMD if you can, you won't regret it.. (Also, the XP's run much cooler then the thunderbirds did, I know that for a fact as the system I have with the XP in it, had a 1.4 Thunderbird in it before, and it ran hotter, (but not hugely so.) Oh, one other thing, for the first time, the XP's have "in CPU" temperature monitor, so the protection is not limited to P4 anymore. In your case, the XP1800, would be about 10-20% faster then a P4 1.6 gig, so its your money. One last tip, AMD don't change CPU sockets anywhere near as much as intel, so Socket A (for amd) will most likely be used for a while now. Intel have released 3 or more different sockets for the P4 now, so in 3 months time, you want to upgrade, you may have to get a new Motherboard as well.. which is more money down the tubes.. If you decide to get a P4 after all, try to get a northwood, as they have the current new type CPU socket, and if you get a 1.6 gig, you won't be able to upgrade it to a 2.2 or above later without replacing the mainboard.. hope all that helps.. rgds Frank -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Brian Durant Sent: Thursday, 7 February 2002 3:29 PM To: Newbie Mandrake Subject: Re(2): [newbie] Building a PC (2). >Again, I strongly recommend an AMD-based system.

The processor is cooler then AMD. If the fan fail then the processor is save because there is a protection for overheat damage. AMD Athlon maybe faster then P4 (in some cases). But most problem I find when work with Athlon is usualy processor broken, because in longterm usage the fan is usually getting weak and it cause the processor not working very well. AMD Athlon XP 1800 is shown on bios is 1.5GHz not 1.8GHz, but AMD claims that the speed is 1.8GHz." Now, I don't know a lot about this, as I say, this will be my first PC. It does seem to be that the price for an AMD Athlon XP 1800 is about $US 50 more than for an Intel P4 1.6GHz at the moment in Indonesia. As to reliability and heat issues, someone please enlighten me. Cheers, Brian
