Despite the fact that the I/O performance hides some of the improvement, the "XP3200+" still shows a healthy boost in performance over the XP3000+. Keep in mind that both processors are running at identical clock speed.

In fact, it showed a larger performance gap (TWO POINT EIGHT TIMES) over the 3000+ than the 3000+ did over the 2800+...at the same clock speed.

To be honest, the performance gain achieved by the Athlon when running in "XP3200+" mode took us a bit by surprise. Sure enough, we expected something to happen but everything being equal and just changing the FSB from 166 to 197 to get a performance increase of 7-8% was more than what we were hoping for. On the other hand, we are finally at the point where we were supposed to be a long time ago, remember, the original Athlon release already projected FSB settings of 400 MHz data rate and that was almost four years ago.

This isn't any type of preview, its actually an excellent comparison of the effect of a 400MHz FSB on an Athlon platform that some sites have touched upon. This quantifies synchronized DDR 400 results, where sites like Tom's and AT have only provided glimpses of DDR 400 performance b/c they were running asynch. Pretty healthy performance increase as long as you keep your timings tight.

i don't know about "owns", but i think that it is pretty clear that this is the processor which should have gotten the 3000+ name.

Read the test setup closely- it just looks overclocked With synced ram timings, it would be more fair to compare an overclocked athlon to an overclocked P4 with similar cooling
XP3000+ 11x197... 13x166
Also right under the Title is "a preview that COULD happen", smells like fish :Q

Really? So you don't think that the Barton 3200+ will have that frequency and that FSB?

Who knows, and who cares. A lot has to happen before the 3200+ specs are released, most importantly official 400MHz support from nVidia/Via. For all we know it'll be released in multiple flavors (266/333/400MHz FSB, etc.), so there could be multiple frequencies and FSB resulting in the final 3200+ PR rating.

Instead of focusing on a PR rating (aren't you totally against PR ratings anyways?), why not call it what it is? Its an excellent comparison of different synchronized FSB frequencies at the same clock frequency. Its something that every overclocker wants to see, but is far too lazy to compile, and something most review sites won't do b/c of its enthusiast/hypothetical/non-off-the-shelf nature.

Yes. They can't come right out and confirm anything can they? But it will happen. The next barton will have a 400mhz FSB effective.

it just looks overclocked With synced ram timings

Very good. not only does it look that way, they came right out and said it. It runs at the same clock frequency (Mhz) as the 3000+ but has a 400Mhz FSB.

it would be more fair to compare an overclocked athlon to an overclocked P4 with similar cooling

Why? It's a 3200+ barton preview. Not a P4 preview. What does cooling have to do with anything?

i'm having a hard time understanding your point. this overclocked set up will run virtually identically to an actual 3200+ (assuming a 200 mHz FSB). actually, i think that the actual 3200+ will run a little faster, as it makes more sense to me for it to be 2.2 gHz (11x200). if anything, this article is being conservative. anyway, the reason that this is a preview that could happen instead of will happen is simply for the fact that AMD hasn't released any 400 mHz FSB chips, so it is conjecture at this point.

How do you know the next Barton will have 400Mhz FSB?
Can I get a link to that?
Also what Athlon motherboard chipset will it run on? I was not aware of any that offically support 400Mhz FSB yet.
Can I get a link to one of those as well?

Officially, no. There are chipsets that will run on a 400FSB and official support will come very soon. It's all about the individual boards though. As for the 400Mhz FSB, it's been remored through "sources inside the company (AMD)" that the next barton will have a 400Mhz fsb and has been in enough media outlets, reliable and not, that it should be common knowledge.

nForce2's as well as KT400a (not released) should be able to support 400mhz FSBs.

Hey it just occured to me that the member rating under my name is similar to an austin powers villain's name. That's kind funny...yes, very toit...(posted something in space that I shouldn't and now I'm posting over it ;))

Nice i didnt know the Nforce2 supported 200Mhz FSB.

So I just rebooted went into the BIOS and lowered the multiplier and raised the FSB to 200.

Processor x86 Family 6 Model 8 Stepping 0 AuthenticAMD ~1904 Mhz

Not to bad for cheap little 1800+ 9.5x200

I dont know if my PC2700 is gonna like running at this speed though. I relaxed the timings to CAS3 just to make sure it wasnt the RAM that would be causing any crashes.

Time to sell my RAM and buy some PC3200 :)

All a barton is , is an xp with a 512KB cache. And everybody can tell you the caches between a p4 and a XP act very differently. The P4 had a huge performance gain with a larger cache over the XP's with a larger cache. However the barton had fewer improvements in the benchmark sector with its larger cache.


Larger cache = larger die = higher price! But like always with AMDs, they will always do more per clock cycle then a pentium.
