AMD Duron Applebred vs. Athlon XP Thoroughbred

CPU by piotke @ 2003-10-07

Recently AMD introduced its new durons. I bought one of them, the 1.6 ghz version. The most interesting part of this cpu is its core voltage, only 1.5 V.
This cpu begged to be compared with an Athlon XP, dlt3c (known for reaching speeds up to 2700Mhz!). Is the new Duron an equally good overclocker ? Maybe even better ? Find out in this review.

SuperPi

SuperPi results:

Lets calculate Pi now. This very small tool is used to calculate the mathematical number pi (3.14...). I always select the option "1M". This means that we're going to calculate pi to 1 million (1 000 000) numbers after the comma.

  • First bench:


  • Madshrimps (c)


    What can we see here ?
    Well, the duron and the XP perform equally good at stock speed. Don't forget, the Athlon is 66 Mhz slower. When I put the Athlon at the same speed as the Duron, meaning 1.6 Ghz, it's 1 second faster. I ran this benchmark a couple of times, but I had always the 1 second difference. Is it the extra cache ?

    I raised the FSB to 200, and lowered the multiplier to 10. Now it are the same cpu's, except for the cache.
    At a speed of 2 Ghz the XP is already three seconds ahead. Hmmm, seems that the limited amount of L2 cache on the Duron is affecting performance.

    The Athlon XP is faster in SuperPi without a doubt. Let's see if this trend changes when we use Sisoft Sandra...
