Which is the faster system? Socket 754 Sempron 2800+ with PC2100 memory or Athlon XP 2800+ with PC2700 memory?

I'd go with the A-XP.
Assuming that they have the same ammount. and the rest of the specs are the same.

Tough call.
Sempron on S754 should still be a little faster than the AXP system even with PC2100 ram. Athlon 64 isn't bandwidth starved. You might lose 10% with this ram but performance increase on 754 socket should be well over 10% at least in games. LINK If you see here 3100+ performs a lot better than 2600+. Even a 2800+ S754 should be faster. If you overclock it, then surely it will be better. At least you can upgrade to A64 3700+ later. With socket A u are stuck at 3200+. But I think spending just a bit more for 939 A64 3000+ venice is worth it.

That's a really good question. The problem is that a million idiots are going to try to answer your question just for the hell of it, without any real evidence.
What you need to do is look at Socket 754 vs Socket A benchmark tests.

You're saying a Sempron (s754) 2800+ will out-perform an Athlon XP 2800+ because a Sempron 3100+ outperforms an Athlon XP 2600+? That makes no sense!

IIRC the 2800 xp has more L2 cache than the sempron 2800 plus the 2700 ram is faster than the 2100...both fsb are 333, so my money is on the xp2800, assuming all other factors are equal...
i would ut my money on the s754 sempron. CBandwidth is not that important to a K8 chip. Run a A64 @ DDR333 with CAS3 ram it it will lose ~5 FPS over the same chip at DDR500 CAS2. Also the L2 cache isnt that big of a deal. 128kb, 256kb and 512kb A64/Semprons are all very close in performance. Overall i think it will come down to raw MHZ speed. If they run at the same or similar mhz, the sempron will win. If the AXP has a huge lead it will probably be faster.
For the most part they'd perform fairly similar but w/ the edge going to the 2800+ @ 2.083 ghz vs the Semprons 1.6ghz, even on skt A an almost 500mhz clock speed advantage negates any of the K8 core advantages so the 2800+ AXP is going to beat the sempron in pretty much everything except the gaming benches, in which they should be fairly close, this doesn't take into account any overclocking through, if you do OC I'd bet the sempron would crush the AXP.

you are joking right? a sempron and an A64 are close in performance???? i have all three and the sempron is not even in the ball park with my 64....but i will give you this, my 64 is a 939 with the memory controller on the chip......i dont have a 745 setup....but i am going to research this tonight and see what is the result...but i cant believe any sempron will compete closely with a 64 set up......L2 cache does make a difference.....

I dont think you realise that the Socket 754 Sempron does have an onboard mem controller,it's basicaly a 32 bit A64 with less cache.so yes a Sempron IS very close in performance compared to a A64.

agreed, and i dont feel like taking the time to resaerch this more.....so i will gracefully bow out of this thread until i can offer a more educated opinion.....
Since the A64 2800+ is only $100 now, I would save myself the trouble and just get that if I were you. It will be fast and run cooler than the XP chip.

No. I said given the performance delta on the socket 754 platform, even 2800+ on S754 should be faster (even with lower cache and slightly slower clock speed). I just linked the article to show the huge performance difference.
If I had to guess, I'd say that the Sempron 2800+ (1.6GHz/256KB/800MHz) would probably out-perform an Athlon XP 2800+ (2.08GHz/512KB/333MHz) in most applications. But that would just be guessing. I have found no benchmark tests that pit the two CPUs against one another.
On the other hand, the "Thoroughbred" 2800+ is quite a marvel. At 2.25 GHz, it excels under certain conditions, namely video editing. Check out THG's benchmarks, where it edges out even the Sempron 3100+: http://www.tomshardware.com/cpu/20041221/cpu_charts-18.html
But, like I said, without proper benchmark testing, it's difficult to say which CPU is "better."
