Dothan Lovin

[Pingu2003]

But whats the % of people using Dothans compared to FX-55's?

There is no denying that Dothans, clock for clock, are the fastest chips on the planet.

absolutely

3.3Ghz clocked dothans reaching low 20's on PI, thats amazing!

I said the same thing in my first post in this thread. That's one truth. Another truth is that the FX-55 (and FX-57 soon) will reach higher clocks, so overall they are still faster. I hope Intel continues to improve the Dothan because AMD sure isn't getting any competion from the normal P4's.

oops

Well I believe this is actually the record. It's not a Dothan though. I doubt the legitimacy of some of those benchies from Asia.

Low 20's on a $1,300.00 (US) CPU on LN2.

And here's mid 20's on a $149.00 (US) CPU on a Vapochill PE.

And the 1MB A64's are much faster than that 3000+.

Here's an FX-53 doing 22 seconds: http://www.xtremesystems.org/forums/...chmentid=11720

The FX-55's and FX-57's are hitting 300+ MHz higher than this. You do the math.

***Politically Correct Disclaimer***

Dothan's are very fast for their clock speeds.

22 seconds, lol

looks like you need to do some maths

[StormPC]

BTW...The benchmark you linked to (mine) was done months ago on one of the first FX-55's. They're much better now.

And as your superpi scores go? I think my aircooled San Diego can do better than the scores in your link. I'll give it a go when I get home.

StormPC what u reckon about the X2 AMD64?you reckon the FX57 will rape it or get PWNed?would be interesting to see...

[oralpain]

Of course the FX-57 (or FX-55) will beat the X2s in single threaded benchmarks. X2 will be about the same as an equally clocked single core chip in pifast.

[StormPC]

Yeah but they'll be great for SETI which is what I'll be using mine for. My FX-55's and 57's will be for benching and gaming though.

I hear all these people talking about X2's for gaming. That's a bad joke. It's not that they'll be bad at games...they will be awesome. It's that the highend singlecores will stomp them for less than half the price.

The entry fee for the X2 will be steep in the beginning I'm afraid.

[oralpain]

I'll be using mine (if I get one) for gaming and everything else. I frequently use FRAPS to record video and have another core/cpu would help with the, esp since I record to a network drive (the files are huge) and that takes a good deal of CPU power itself. The X2 4800+ is rediculosly expensive, but the lower modles aren't outrageous.

On the topic of Dothans, has anyone seen any reviews on the new AOpen i915GM board? It uses the new mobile chipset and supports single channel DDR and dual channel DDR2-533, has tons of features on it too. I'd like to know how it performs compaired to the ASUS board + 479 adaptor. It's the most expensive non-server board ive ever seen though.

Based on what you just typed the X2 is not going to help you much. You may have applications you failed to mention that will benefit more from the X2, but if you mostly game then X2 is a really bad idea in terms of cost vs performance. And if you think the lower-end X2's will be reasonably priced you are very wrong. In the beginning it will be FAR worse than the ATI X800 XT PE and X850 XT PE fiascos. The X850 XT PE is still going for $200-$400 US over retail because of demand. The demand is going to be huge for the X2 because of the hype. You won't be touching even the slowest X2 for under $1000 US for the next few months.

Dualcores are much more expensive to make than the singlecores so they will never be cheaper. If you don't have an application that uses the advantages of a second core (most people do not) X2's are not for you. If you've never thought about buying a dual CPU you probably have no use for an X2.

On the Dothan board, I don't think it'll be as fast as the ASUS but it's microATX which is sort of cool.

I've always been able to get chips at or near the announced 1000 unit costs. Thats about 500 bucks for the 2.2Ghz 1M L2 dual core. Someone will ahve them some where for prices that are not horribly inflated and if they don't, I'm not in a big rush, I can wait a month or a year. I never expect them to be cheaper, but I do expect them to end up near or slightly under the price of two separate comparable single core CPUs.

I think dual core would help me significantly. I get significant choppiness/hitching when recording at anything past 800x600 to my network drive. 30% of my CPU is being used by FRAPS and my network card. When I'm done recording I have to edit/encode everything and I would be nice if I could do other stuff while I wait without huge slowdowns.

The only ASUS boards that are compatable with that S479 adaptor are AGP only, my next video card will definatly be PCI-E. The AOpen board shouldn't be much slower, if at all, and might overclock better. Time will tell I guess.

915 + CT479 Compatible

tis a socket 478 915 Chipset board, taking both ddr and ddr2, and is pci-e

I'd like to see dualcore Dothans. Monster crunchers for sure.

Interesting board, however it only takes DDR, not DDR-II. This is not really a downside.

I'm seriously considering getting one of these, if it's confirmed to work with the adaptor.

Here's an update. Was able to break 30 seconds easily on air. Slowed my RAM down to try and even up the bandwidth a bit.

Can you run the Dothan on version 1.4 stock to get a better comparison?

Thanks.

couldnt find the 1.4 mod, just been passed on by a mate today:



note: its my media rig so the kids use it too
