They are very close in performance all three.

It's very hard to say which one of them will perform the best, I think it will vary depending on the game / benchmark.

I would go with the Socket 754 system if building an Windows 2000 / Windows XP system. It's probably the slowest in most tasks but you can upgrade it to an Athlon 64 3200+, 3500+ or 3700+ later if needed.

ohh right. in some benchs both the sempron and athlon performed a lot better than the pentium 4, and the sempron was a little better in memory benchs against the athlon, possibly due to hypertransport?

chances are that i never be able to upgrade these machines, either money problems or hard to find at a good price here in Argentina. so i will be using the sempron with a x1650, the athlon with a 9200se and the p4 with a mx4000

none of these are good or retro videocards, but i don't care because the use for these computers is mostly as test machines for various software/games and pc components

The Socket 754 Sempron has a built in memory controller.

All three systems use single channel DDR memory.

The Socket 754 Sempron has a built in memory controller.

All three systems use single channel DDR memory.

The Sempron should also be capable of being underclocked for any speed sensitive Win98 games.

Here are some benchmarks of an AMD Sempron 3100+ and your Athon XP 2400+, so you can compare them directly.

Remember that the Sempron 3100+ has 200 Mhz more and double the L2 cache compared to your Sempron.

ooh, didn't know that

don't know about that, the bios in the mobo that i'm using is very limited, very few options for overclock/underclock, also, that computer is going to have XP, for 9x/DOS games I have various older pc's

i see, so both the athlon and the sempron are very close in benchs, because the sempron there is a little bit faster than mine.

Thanks guys

This can potentially be done via the MSR registers without menu options in the BIOS screen.

thanks, didn't know about that method

If it's a Sempron64, then overclocking the Sempron 😀
note that Sempron64s have SSE2 so it puts it an edge over AthlonXP there. OC'd Sempron64 systems were an underrated upgrade path in the day

Could be, I have to figure out how to overclock on that limited bios, I'm used to more complete motherboards where the bios setup is better and more customizable.
