Athlon 64 2800+ is a Sempron 3100+ with twice the L2 cache and 64-bit extensions. Which one do you think is faster? :D

The similarities: 1) Both run at 1.8GHz stock speed, 2) both have the on-die memory controller (which is the BIG performance advantage), 3) both are available in S754, 4) both support MMX+, 3DNow!+, SSE, and SSE2 instructions.

The differences: 1) The Sempron is $15-$20USD cheaper than the 2800+, 2) the Sempron does NOT support 64-bit instructions, 3) the Sempron has 1/2 the L2 cache (256 vs. 512), 4) ALL Semprons (currently) have the newer CG stepping revision (2800+ have both the older C0 stepping and CG stepping revisions available, so you need to check what you're getting when purchasing).

Links to reviews: Xbit Labs (http://www.xbitlabs.com/articles/cpu/display/sempron-3100-oc.html), the Tech Report (http://tech-report.com/reviews/2004q3/sempron/index.x?pg=1), Sharky Extreme (http://www.sharkyextreme.com/hardware/cpu/article.php/3261_3398581__6) (doesn't compare the 2800+, but a 3400+ is in there), and a new one (from the frontpage of nVNews today) at Dev Hardware (http://www.devhardware.com/c/a/Computer-Processors/AMD-Sempron-3100-Review/), which compares it to the 3200+.
Hope this helps.

Which one do you think is faster? :DTrue, the 2800+ is faster, but only marginally (~5-7 fps in games (http://www.xbitlabs.com/articles/cpu/display/sempron-3100-oc_10.html)). For those on a very tight budget (where ~$15-$20USD can be the difference between getting new hardware or not), it may not be worth it. The 64-bit extensions have absolutely ZERO to do with the speed in current 32-bit applications, although they help to "future-proof" for when 64-bit Windows is out (not beta). It's the L2 cache making the 2800+ slightly faster.

Thanks you all :)

this evening i'm going with a friend to buy his new pc, he is even saving money from mouse keyboards and so lol so i really think he will buy a 3100+ :)

I never meant to say that 64-bit extensions will increase performance under a 32-bit environment, I hope that's not what you assumed from what I wrote. Yes, 64-bit extensions are merely a feature advantage for now. I've always been one to actively stress this in the past.

I did read your above post as touting the 64-bit aspect as a speed benefit.
The Dev Hardware review I linked above is interesting in that it pits the Sempron against a 3200+ (which has a 200MHz speed advantage AND a full MB of L2 cache), and the Sempron actually did better in some of the benches, and never really got owned in any of them.

Sempron has the advantage of overclocking if you are intrested.

Well if you realy need to save the money, I guess the Sempron wins.

Your not going to need to use 64-bit extentions for a while. I think it is nonsense to by a lowend 64- bit processor when you are not going to use 64-bit programs for a while, and when you do the prices for 3200+ and 3400+ would be cheaper.
