Dothan@2.6Ghz(Air) matches all else! 2.8Ghz rocks!!!!

They've crippled A64 with slower memory timing,

...and on another note, the dothan platform used also cripples the CPU terribly with single-channel memory and lower-than-optimal FSB. The difference being, of course, that we can't change that, but A64s can be used with better timings right <i>now</i>.

As is, right now, <b>dothan isn't quite on par with desktop processors indeed, but that's NOW.</b> But going to 533Mhz FSB and dual DDR2-533 can boost performance by something in the lines of 15% or more. We'll be seeing that in the next 2 months or so in the sonoma platform. If dothan were to sit on LGA775's 800/1066Mhz FSB, then... who knows...

You just made my point for me. Thats two people with A64's that get to 2.8 or more on air. Maybe my reply was badly formulated. So thats two instances of high clocked A64's on air and one for the dothan? Both cpu's seem highly overclockable (and when you READ the review you can see that they used 2 or three different cpu's.

And screenshot stable at 3ghz isn't representative or they would have had pi with it.

Dothan is just interresting and promising but not a real desktop platform is it.

For those that understand here's something about Yonahs successor (yonah is dual core dothan): <A HREF="http:// http://www.tweakers.net/nieuws/35004 " target="_new">http:// http://www.tweakers.net/nieuws/35004 </A>

"And screenshot stable at 3ghz isn't representative or they would have had pi with it."

i didnt say it was did i? I pointed out the pi the user got at 2.8, i never said anyhting about the 3ghz pic other then it was there, not that it was even stable.

ok lets just boil this down here. You are saying that both the dothan and winchester(90nm athlon 64) are both intersting and promising correct? both have shown possible large gains in overclocking, so both are on equal footing there.

i dont know, i wonder. can a fsb change fix dothan's shortcomings? Its going to need a revision, imo, before it can hit primetime on the desktop. you couldnt just drop a dothan in its form now onto lga755 and magically all its problems dissapear. FSB will not help FP. I belive there will need ot be an archetecture redesign before we see mass dothan on the desktop. remeber they still need 64bit and maybe hyperthreading. that would definitely require a redesign of some sort.

also, once agian, they gave no temps or power draw numbers when the processor was overclocked, why is that? Thats all Ive wanted to see this whole time. i knew at stock speeds its temp would be lower, but I want to know how it scales heat wise, or did i miss those numbers?

but i have to say there are bright spots for dothan, but we all already knew that. im sure intel lieks seeing dothan close the gap in some games, or maybe they dont care lol.

the last hting ill say is taht I hope they lower prices on motherbaords/cpus. $275 for the motherbaord is a bit steep imo.

 

[mopeygoth]

aye, but still the gameperformance is impressive considered the single ch. pc2700

What I find interesting is Dothan vs. Pentium4, A64 is not to be forgotten of course, but it's the idea of the invisible roadmap 😉

Abit IC7 Max II Advance - P4E3.0@3.45- i875P - 1024mb dual ddr400 3-2-2-6 - Leadtek 6800 128mb@380/850 - 600W dualfan(front/rear) PowerTek Psu - maxtor 4K080H4 & 6Y120P0 - samsung sm-352b

FSB will not help FP.

Oh, but it will.

2.0Ghz Dothan, 400Mhz FSB:
Spec_FP: 1087
2.13Ghz Dothan, 533Mhz FSB:
Spec_FP: 1304

That's a solid 20% increase in floating point performance. There's no way this can be attributed solely to the 6% increase in clock!

Anyone know how high the A64 is planned to scale?

 

[trooper11]

welll i guess so then, but ill reserve judgement till we see more concrete tests concerning that. i just odnt see how dothan holds its own in its current form. you know it doesnt stack up to the desktop parts ocmpletely right. how many times have we seen bumps in fsb or ram support, only to find it doesnt give much real world affect. just look at how little the move to ddr2 667 did for the p4. perhaps the dothan will be different, but ill wait and see.

cpuz says the architecture of mine is made for 3ghz. I've got a dh7-cg 130nm. 90nm have slicht achitectural changes and the E (or J) stepping has SSE3 and better memory contrioller and maybe made for higer speeds.

Interesting =) I'm curious about AMD's plans, like how far do they plan to take the current architecture before they absolutely have to do a redesign. Intel is changing course now, but AMD will face this part of the product cycle at some point too.

 

[Xeon]

AMD will need to save those pennies for a bit longer I would think.

AMD's next redesign is the K10 and that will come sometime in 2006. Since the current athlon 64 was designed with dual core in mind, it willl make the transition to dual core or the 'K9' and willl head into 2006. But K10 has been started design wise for some time, so itll be intersting to hear details as they come to light.
