ASUS EAX1800XT TOP/2DHTV/512M, DF core/mem 670/800, 3DMark05 9695

Highly unlikely, or very, very biased.

9695/8760 = 1,1067351598173515981735159817352
That is more than 10% improvement (almost 11%)!

Not even if you multiply core oc by memory oc you get more than 8%!
In fact you only get
650/625 * 1650/1600 ~ +1,074667

Unless it's their external PSU ofc.

...

Or, second possibility (most probable, since I just noticed the "Hardware Specification" table ): Original X-bit labs reports were wrong: The real specs of this ASUS card are 670/1600, which would make a whole more lot of sense.

(670/625=1,072) * (1600/1500~1,0667) ~ 1,1434667 ~ +14.3%
And of course, it doesn't scale like core oc * mem oc, so 10% is very plausible to be a more correct number.

Also the external PSU is only 80W + 75W through PCI-e = 155W power consumption of the card? That's not very much at all. In fact, I'm not confident it's enough power for any good OC combined with a vcore raise.

edit: Yes, and please, keep all the thread crapping and flame baiting out of here, this is also goes for those who may be right in a factual matter but are displaying an immature attitude towards others and their contributions to the discussion (may they in turn be right, wrong, flaming themselves or neither - doesn't matter). Thank you for your understanding and cooperation!

Currently, the standard clock settings for the Radeon X1800 XT are 625MHz for core and 750MHz (1500MHz data rate) for memory. Because ATI is experience good yields on the Radeon X1800 XT core, it is allowing boards to be overclocked to 700MHz core and 800MHz memory (1600MHz data rate). In the document, ATI also indicates that standard clock settings are often set at conservative speeds to produce the highest output yield possible.

Good yields hehe... where's the stock/availability though ???

[DilTech]

The 700mhz/1600mhz is the XTPE, for those who didn't know. Looks like ASUS's 650/1500 is just their overclocked model.

670/800 EAX1800XT Change 700/800





The EAX1800XT TOP should be available starting from at the end of November for 529 euro in the trade. Contained in the scope of supply the plays joint are operation, Snowblind and King Kong (DVD).

Thanks SXS For the update and the pics

This just became the unofficial X1800XTPE thread....no talk of the XT here, or what compares with what, or XT's issues etc. Thx.

Once reviews start comin in, a seperate thread will be made for that too. Otherwise all XTPE discussion goes here

Looks like ATI is back after a little GTX scare. If they are indeed launching the R580 in Jan/Feb they are back on top without question.

[5-Clicks]

doesn't Newegg ship to Canada? I remember them saying that by October they'll have a warehouse in Canada and will be shipping there. IIRC, they also said that they'll eventually ship worldwide. I might be wrong about that last part though.

And I would say that the X1800XT's are pretty fairly available compared to their other launches. I remember the X800XT PE that wasn't available anywhere for longer than 10 minutes and even then they were $630 USD for about 6+ months.

For an X1800XT PE to hit 700/800, it seems that ATI will only have to bump up the volts by about .3v-.5v and they'll get more frequently hitting PE core and mem, am I correct?

If we assumed that they are binned differently, then 700/800 isnt a problem...but I was expecting 725/850

Very strange looking card...I think ASUS could have did a better job on the Heatsink/Fan design...I want to see what HIS and Saphire so with theres.

[onewingedangel]

Well the card has a huge lump of copper on it, but all the heat removed is dumped back into the case, so the case temp is higher, and so its more difficult to remove the heat from the heatsink. Not the best design decision really. Cant artic cooling nv silencers be fitted to this card? Expect HIS to release a x1800xtpe with arctic silencer soon enough... and we may even see some cards with the 7800gtx512mb's cooler.

Would like to see some new heatsink designs though. And with crossfire and SLi now so popular why not have cards that have heatsinks you can place standard fans on the push the air out of the rear of the case, so for example you put an 80mm fan on it if its a single card, or put a 92 or 120mm fan to cool 2 cards in sli or crossfire. Having a 120mm panaflo at 7v cooling 2 graphics cards would quieten an air cooled computer down no end.

[ugp]

Yeah that is an issue I have now with SLI. The heat is so much and with the Chipset being there it takes the hot air and pulls it in and causes the chipset to be hotter.

[SDX]

If ATI was smart they would put the 1.1ns GDDR3 on the PE
and stock clocks of
700-725/850-900

[perkam]

Thats a very good question

If ati launch 580 in january that means killing x1800xt sales, cause with this tempo it still might be unavailable at this point.

If ati want their phantom edition to do what it should (beat 512 GTX with a few FPS to claim they have the fastest card (even thou it's nowhere to be found))... it will need more juice, this clospeed wont get it anywhere near the GTX 512. 700/800 might help it with 3dm 2005 but in games it will need more...

Let's stay on topic here No mention of the XT unless its in relation to the PE, thx

But yes you're right, even I'm not too satisfied with the clocks and most will not buy them knowing what we know: that 700/800 isn't too hard on the XT for ~$100 less...

I'm looking forward to the cooling solution the HIS will have

You have to consider that the r580 will be out in a few months, so you want to be able to leave enough room for it to have a performance boost over r520. and one way is to limit the clocks of the PE so that when the r580 at say 750mhz comes out it shows marked improvement over the r520, even if situations where the additional pixel shaders etc. aren't used. Same goes for the ram. Using 1.4ns ram at 1600mhz leaves room for 1.1ns ram to be used at 1800mhz on the r580 cards.

You mean using 1.26ns ram leaves room for 1.1ns?

[onewingedangel]

yeah, 1.4ns is 1430mhz isnt it. My mistake.

[perkam]

I believe ATI execs have said multiple times that 2006 will be the year for GDDR4

Perkam

[ugp]

I wonder how DDR4 will overclock...

[saaya]

i wonder what ati does with the chips that dont have all the 4 quads working?
or maybe there are barely any with damaged quads because they been improving the vpu for a looong time trying to fix the problem wich turned out to be something else?

but still, there must be some with only 3 quads working, where do those chips go?

[perkam]

Well, as far as we know today, Samsung will start mass producing 0.8ns GDDR4 chips in 06 which is 2500Mhz stock.

X1800PRO...to go against Nvidia's 7800GS ...

I'm eager to see what other companies have to offer cooler wise...this one looks uglier by the second.

[MaxxxRacer]

saaya as perk just said they will release lower end x1800's at a later time. They probably just dont have enough borked ones (much less working ones) to release the x1800pro in numbers.
