Quantify our machines performance

Since I posted the specs of my main Linux computer in my signature block I have received numerous questions in threads as well as private messages regarding the performance of my box. Some have argued that my choice of a Sempron processor is a mistake and they would have spent more for the genuine Athlon.

So, I wanted to help quantify some of the numbers and give some benchmarks that we can all relate to and duplicate to determine relative performance of boxes.

My tests are all done using a standard install of FC5. I386 version from CD rom's. I went stritcly with defaults, no customizing of packages. I did the default partitioning (using LVM) and essentially just went next, next, next, finish through the installer.

Machine #1
**************
Sempron 2800+, Gigabyte GA K8VM800M mobo, 1GB RAM, FX5200 video, 60GB WD IDE HD
Install time = 20:15
Boot time (from grub to logon screen) = 46 seconds
From logon to full desktop with icons = 6.3 seconds
From shutdown to machine power off = 19 seconds

Machine #2
**************
Dell Dimension 8400, P4 @ 3.2ghz, 2GB RAM, 256MB Radeon X800XT PCI-X, 60GB WD IDE HD
Install time = 18:50
Boot time (from grub to logon screen) = 42 seconds
From logon to full desktop with icons = 6.1 seconds
From shutdown to machine power off = 19 seconds

Machine #3
****************
Dell Optiplex GX150, P3 @1.0ghz, 512MB RAM, 815 on-board video, 20GB IDE HD
Install time = TBA
Boot time (from grub to logon screen) = TBA
From logon to full desktop with icons = TBA
From shutdown to machine power off = TBA

So, my main point was that althought there is a signficant cost difference between Machine #1 and Machine #2, there is very little tangible difference in FC5 between the two machines.


Anybody else care to share the results of their machines for comparison sake?

The tasks you are timing are hard disk intensive.... and you have the same hard drive on each machine.

On the other hand, it wouldn't surprise me if a sempron gave a p4 a run for its money.

Give us better tests to judge performance. (Rip a CD or something)

One of my machines uses a Sempron 2800 as well, and it's almost indistinguishable compared to a P4 3.0. With some apps, it's even faster.

I recently purchased a Athlon 64 X2 3800 and noticed a huge improvement over my 3.2ghz P4, when it compiles and things like that, it could be to do with the flags I'm using in GCC though.

The Althon has a lot more ram (1.5gb vs 512mb) and is using SATA 2 rather than IDE as well, so not sure how reliable a comparrison it is.

The ram probably accounts for most of the difference. The processor will certainly have in impact.

From what I have seen, most SATA and SATA2 drives perform the same as IDE. Obviously the specs would lead you to believe otherwise, but my IDE's run about 47MB/sec while my SATA runs at 49MB/sec and my SATA2 at 50MB/sec. For most things, that's imperceivable.
