Performance

Now we’ve got to the most interesting part of this review – the examination of the performance level of the overclocked Sempron 3100+ processor. If this level is rather low, why bother about overclocking it at all, yes? So, our Sempron 3100+ is overclocked to 2.52GHz, and we’ve got two Intel Pentium 4 3.4GHz CPUs on Prescott and Northwood cores, and another Socket 754 processor, the Athlon 3400+ to serve as reference points.

We used the following hardware in the test platforms:

  • Processors:
    • AMD Sempron 3100+,
    • AMD Athlon 64 2800+,
    • AMD Athlon 64 3400+,
    • Intel Pentium 4 3.4E (Prescott),
    • Intel Pentium 4 3.4 (Northwood);
  • Mainboards:
    • ASUS P4P800-E Deluxe (Socket 478, i865PE),
    • EPoX EP-8KDA3+ (Socket 754, NVIDIA nForce3 250);
  • Memory:
    • 1024MB DDR400 SDRAM (2 x 512MB, 2-2-2-5);
    • 1024MB DDR500 SDRAM (2 x 512MB, 2.5-3-3-6);
  • Graphics card: ASUS RADEON 9800XT;
  • Disk subsystem: Western Digital WD400JB.

We performed our tests in Windows XP with Service Pack 2 and DirectX 9.0c installed. The BIOS Setup of the mainboards was set up for the maximum performance.

To get a preliminary estimate of the performance level of the Sempron 3100+ overclocked to 2.52GHz we launched the SuperPi test, popular among overclockers:

As you see, this benchmark says the performance of the overclocked CPU is real high. Thanks to its clock rate, which is higher than that of any Athlon 64, the Sempron 3100+ outperforms the Athlon 64 3400+ as well as both Pentium 4 with a frequency of 3.4GHz! Well, if it is the same in other tests, the Sempron 3100+ overclocking should be considered as a highly profitable business! Let’s see…
