Nice article, I wish they'd have included a 3000+ winnie at ~300x9 though, woulda smoked em all . Sucks there's no multiplier adjustment on those, maybe AMD will release some mobile semprons soon .

I am considering moving to that setup from my 2.4 Athlon XP..

Might be worth the $100

the more interesting result of this pretty good article is that the sempron 2800+ is poor value in comparison to the 2600+. It should probably be renamed the 2700+. The extra cache makes a small difference to the performance, certainly not as much as the extra 200 PR points suggest. Even in Winrar, the most cache-sensitive app, the speed diference is overall 6%.

And

'In our tests the processor with a 128KB L2 cache is in average only 1.2% slower than its analog with twice the size of the cache and less than 6% slower than the model with an L2 cache of the maximum size.' The extra cache only matters for games, certainly for office use, the socket 754 semprons are a screamingly obvious buy (and these days few users not gaming need more speed_

This makes sense - my memtest86 scores show that the level 2 cache is not hugely faster than my RAM.

Silly me for buying the 2800+ already (although the 2600+ wasn't available when I bought my 2800+).

But the good news is that the Sempron chips can be more-or-less directly compared with the A64 chips - the real difference is the lack of 64 bit instructions (which doesn't matter yet)....

So
Sempron 2600+ = 8x multiplier - best buy @ $78
Sempron 3000+ = 9x multiplier - 12.5% faster, 33% more expensive at $99, plus adds Cool N Quiet
Athlon 64 3000+ = 10x multiplier - 25% faster, 100% more expensive at $165

So buy the nice cool 2600+ and overclock it.

Note it isn't completely an Apples to Apples comparison they used CG stepping for 256KB - 1MB and D0 stepping for 128KB, it would be interesting to see how it compares if they got an actual Sempron 2800+ to test.

There's a vender on pricewatch that claims to have a mobile athlon 64 2800 with 256 megs cache, but it may be a sempron. It should also overclock very well, with the fsb at 133. But heatsinks are difficult to find for mobiles.

that's ALOT of cache! lmao..

This is old news. I have a thread in this forum on the same exact thing.
I got a 2800+ off Monarch for $88. It's stuck at 2.4, only limited by my motherboard. I'm using 1.475v for it to keep it prime stable. It could probably be stable off lower, but my motherboard doesn't allow any further undervolting. Will be installing a DFI soon.

1.6v will most likely get you to 1.6 for sure..

good luck!
