Barton 3000 vs. Sempron 3000

i am just curious as to which of these two would perform better, both are barton cores (at leas according to thislist ) and both have similar mhz. i would lean towards the barton except semprons are supposed to be better performers at less mhz, and also are cheaper.

The Athlon XP Barton.

They are both the same core, although since the Athlon XP was designed to compete with the Pentium 4 and the Sempron is designed to compete with the Celeron, the Sempron is actually slower with an inflated "performance rating."

In fact, both being the same core, the Sempron runs at 2.0GHz, and the Athlon XP runs at 2.166GHz.

I might also add that certain XP 3000's are 400 FSB models. They do run however, at 2.133GHz, but the extra front side bus gives you a nice gain.

The Sempron is like the 2.166GHz XP though, it only has 333 FSB.

If you are looking to overclock, you would probably get the same or better results for cheaper with a 2500 or 2600 XP mobile CPU.

Both cpus run at 333mhz fsb. The only difference I think, is that the barton has 512k cache.
This is intresting
AMD Sempron 3000+ 2.0Ghz Socket A/462 512KB L2 Cache 333MHz FSB
AMD Sempron 3000+ 1.8Ghz Socket 754 128KB L2 Cache 333MHz FSB
Big difference in cache size for the sockets.
Thanks

The barton...the semprons run good but the bartons seem to have a slight edge in games...if you want to oc get a 2500 mobile

Me 2600 mobile does 2.7ghz on air at 1.9v and less than 60C under load. Superiority, pure sublime. Ye have to watch the steppings though because not all are this good.

Great info, but I beleive he was comparing two Barton cores. A Barton Sempron and a Barton Athlon XP. And yes, AMD does make a 512K L2 Barton Sempron Socket 462.

BTW, I beleive the Socket 754 versions actually have a 400MHz FSB, or Hyper Transport thingy..whatever they call it now. AMD just made a typo on their site. Unless, the many who told me so are wrong.

while we are at it, could someone sort out the socket thing for me? i thought athlonXP's were socket A, i don't know what socket 754 or 462 are . . .

The Barton Sempron (there is only one and it's the Socket A Sempron 3000+) performs a little slower than a Barton XP2800+. Both are 333MHz but the Sempron has a multiplier of 12 while the Barton 2800+ has 12.5. The 333MHz Barton XP3000+ is even faster with 13.

AMD never officially released a Barton XP2700+ but if it had it would be identical to the Barton Sempron 3000+. (The Barton XP2600+ has a multiplier of 11.5 but they skipped 12 until BS3000+.)

Definitely look at A64 alternatives! But if you're not ready to make the big leap, your motherboard cries for a mobile XP2600+!

Socket A Athlon XP 3000+ Barton
vs.
Socket A Sempron 3000+ Barton
-------------------------

The same cores, with the same amount of cache, same default FSB, except Athlon XP version's deafult multiplier is 13 and Sempron's is 12.


SO

13 x 166
vs
12 x 166

Otherwise, the same chip, which one you wish to get depends how high your mobo+RAM will allow FSB to be overclocked

so you take that info into account because the multipliers are locked at 13 or 12....

I KNOW I WANT A MOBILE BUT THEY R SO EXPENSIVE HERE IN ARGENTINA!!!
free mobile for me anyone? think of my mobo . . . it's CRYING FOR IT.
i'll send some dulce de leche to the kind soul . . .

joking aside, i guess the sempron would be my choice since i have plenty of head room in FSB, while the barton would leave me cooling-impaired before it maxes. no cooling issues with those lovely mobiles . . .

Well, looking at your signature you have an unlocked TBredB 2400+ running at 12x200 so you have an idea how a BS3000+ will run at 200MHz. (In some apps it will be identical in others the extra 256K L2 cache will help.)

It's certainly within reason to also get the BS3000+ to 12x200 or 2.4GHz, maybe even more, 12x208 would be about 2.5GHz so really the BS is getting into the mobile arena. The 333MHz XP3000 with 13x would make it nearly impossible.

You might want to do some memtesting before buying a locked chip. Drop your multiplier down to 10 or so and see how fast you can push your RAM. Maybe 210, maybe 220. Then use that to gauge which multiplier you want. First try to do it with your Tbred but realistically the Sempron or maybe even better, a Barton XP2600+ with its 11.5 multiplier would give you a better overclock. If your RAM was stable at 230 (maybe upping your vDIMM) then a Barton XP2500 might be best with the 11 multiplier.

Or you may be satisfied with the Tbred at your highest FSB and drop the multiplier to 11.5 or 11. (That's the best overclock because it's free!)

Socket 462 is socket A (K7 based CPUs)
K8 architecture (the new AMD's, ondie memory controller, etc.) Socket 754,939, and 940.

I was going to start another thread, but then i searched and I have a question very similar to this one.

Would a Sempron 3000+ 512 L2 cache perform better than a Athlon XP 2500+?

How much of a performance gain would i expect from putting in a sempron?

3000+ Sempron is 166 MHz faster than 2500+ Barton at stock speeds.

If overclocking, newer 2500+ Barton is expected to overclock similar/the same on average as 3000+ Sempron because 3000+ Sempron is the only Sempron based on the Barton core...
