AMD Athlon XP vs Intel Pentium 4
Does anyone know if the newest AMD Athlon XP is better (speedwise) at running a 16-bit application (Fractint, of course) than the newest Pentium 4's? (Gathering upgrade information) Thanks, Lee Skinner
Check Tom's Hardware Guide, and Anandtech.com.
From what I see on both, Athlon XP keeps up with the Pentium 4, despite its slower clock speed (compared to the newest P4s), and beats them in most throughput tests.
Of course, don't believe any of those sites test using Fractint or any other 16-bit app. ;-) David gnome@hawaii.rr.com On 17 Feb 02, at 19:05, Lee Skinner wrote:

At the same clock speed the Athlon tends to be considerably faster in most situations. Intel made some architectural changes in the P4 that make it rather bad at running legacy code, so I expect this will make the Athlon an even more atractive choice for running Fractint. A lot has been written about Athlon vs. P4. Check the archives at Tom's Hardware or Ars Technica (among others) for more in-depth technical reviews. Hope that was helpful, Pedro Lopes

Thanks Pedro, I too will get a new machine when there is a speed-increasement of about 5x (versus the now used 600Mhz Athlon-K7). So I will install a partition with an old DOS (6.22) specially for Fractint.

cheers, Guy *********** I had big troubles with PC-virusses transmitted to me per email, passing the filters of our email server. If you had an attach-file from me, carefully scan it with a Virus detector before runnig/starting it by double klicking!! Although no virus was declared active by Norton Antivir, a worm possibly sent itself to all addresses of my email program. Anyway, my PC was down for a certain time. It's now ok again and email attachments are scanned by antivirus software. Please give me an information if you got a virus-infected email attachment in the last 2-3 weeks from me: guy.marson@mnhn.lu ***********

I tend to go in doubles. Currently using a 700MHz Duron in one box, which was bought to replace the 350- MHz K6-2 box. My next jump requires a motherboard replacement, so something in the 1.4GHz range would be OK. It'll be awhile before I jump higher than that, probably. The bottlenecks in PC performance are such that speeds higher than that produce little difference in actual performance. As one e-mail tagline I've seen said, "All computers wait at the same speed!"

While that's true for many applications, for Fractint what really matters is raw CPU speed. That means you can actually gain from upgrading to a faster processor even if the performance of the other parts of the system remains the same. Fractint doesn't even care about memory bandwidht, which is a typical bottleneck for other number-crunching applications that have to consume/produce a lot of data. So the bottom line is, if creating fractals is the main factor in buying a new machine, all you really need to look for is a fast CPU. Pedro
How is Fractint effected by the P4's less-optimal execution of 16-bit code? I think I'd still prefer running it on an AMD processor. The only point where a P4 outdoes the Athlons is the specialized task of encoding video streams. Of course, I usually run Fractint as a task under OS/2 (used to try with Windows, but W95 can't really multitask DOS apps) and use the system for other things while it's calculating, so the system needs more than just a fast processor. It would be nice to be like Jim Muth and have a machine around just to run fractals on! David gnome@hawaii.rr.com On 19 Feb 2002, at 10:20, Pedro Lopes wrote:

ohhh.. I will test it as I did it 2 years ago..
