both i think
Just to be clear, if I had two 3870's on a board with 3 PCI-E x16 slots, could I add a 3870 x2 and have quad fire, or would I need to trade out the two cards I have?
I believe quadfire is only 2 3870x2's.Quote:

In theory it would work but I think there is a GPU limit, which is why the HD 3870X2 doesn't allow CrossFireX.Quote:

How about Octo-Fire?
4xPCI-E slots anyone?
:D
It could be enabled via software, but the lack of 2 bridge connectors on 3870 X2's is kind of a problem...Quote:

It's only as long as an 8800GTX :up:Quote:

However that still questions the fact how the system would respond to that.
Technically sounds possible but the 3rd card would be running on the slow PCIe slot which could spoil the whole thing. Only thing left is to wait and see.
So far the public has been informed that "X-fire = 'up to 4 gpu's ", that's it. If it were 'technically possible' to have more than 4, ATI would have said it.
Anyway. we haven't even seen the real performance of two of these in CF yet. That'll be THE news i have been waiting for.
Essentially 2 of them = Quad Fire;) Why would you need anything more quite honestly?

3870cf is capable of 1920*1200 and 8(!!)xAA with 60+fps in games like Oblivion, FEAR, COH and many more.
So, yes, in my opinion it DOES matter.
You can call it a problem or whatever, but 3870cf is only like 10-20% behind 8800gt SLI in 4xAA while being like 20-30% ahead in 8xAA.
I really don't see anything of a big AA problem here or at least nothing that will me stop using AA.(except those limited bandwidth)
We have not seen real test reviews yet. Who would buy this card (i want 2) before he/she has considered those results first? I wouldn't.
My 3870 already is a boost of roughly 30% over my old X1900XT. I bought this Maximus so i can have quadfire. If quadfire does not work in certain (old) titles (that don't really need it anyway) and in those cases it would stick to single 3870 performance, i wouldn't care.
What i want = max performance and IQ in the heaviest titles @ 1600x1200 now,
AND later this year i may have a 1900x1200 24" flatscreen, then i want the same performance.
IF quadfire RV680 cannot deliver that, i'll sit on my 800 euros and wait for the R700.

Detailed 3870 X2 Cooler Pics Surface
Although plenty of Radeon HD 3870 X2 pictures have found their way onto the internet, there has been relatively little to look at when it comes to cooling. CHIPHELL has managed to get hold of some nice close-ups, which you can see below. Based on initial impressions, the cooler doesn’t look too impressive, but at the end of the day it’s real world performance that counts so we’ll have to wait and see.

The Asus HD3870X2 has now been listed on Salland.eu for 382 euro's. Very nice price imo, since it isn't the cheapest GPU store in the Netherlands. Availible in 1 to 10 days.
Not sure what that black thing is to the left of the cables in that bottom picture above. A thermometer perhaps?
Looks like screwdriver with led light attachments :D
http://img3.pconline.com.cn/pconline...248_mthumb.jpg
Well the interesting thing is that 825+ core clocks seem to exist and that PCIE2.0 increases performance of the 3870X2 greatly. Looks like PCIE2.0's full use is finally come around.
GDDR3?
This card excites me very much regardless.
NDA ends Wednesday I hear, so expect some results to pop up around then :)
I "heard" that :
GDDR3
Temp idle = 57º (fan auto)
CCC dont have Crossfire option and GPU-Z detects CF disable

Wow. :yawn2: Maybe we can have some real info on Wednesday. Who knows.
Just be carefull what you put in your mouth overthere or you'll turn into a lizard.Quote:

As you know, on the board ATI Radeon HD 3870 X2 is two graphics processor. According to the information available at the reference motherboard ATI Radeon HD 3870 X2 will be installed 1 GB of memory GDDR3, which operates at a frequency of 2 GHz processors and related 256 - bit tyres. The product is meant for connecting to the bus PCI Express 2.0, which interact with the responsibility of the special chip-bridge. The truth seems to be in this role will not be used PEX6347 ,as expected but PEX8548. At the given scheme, the bridge is at the centre of charges between the two processors. Near each processor can be found on four chip memory.
The following illustration shows that the transition from PCI Express 1.1 for PCI Express 2.0 provides a noticeable increase in productivity - around 20-30%, depending on the application and the screen resolution.

3870x2 is pretty much same as single 3870 in idle as you can turn off 1 core.
It just seems more relevant to point out the wattage. I could of mentioned percent but there was only one variable. With the performance increase there were multiple variables averaged. Plus I was just quoting the guy from VR-Zone.Quote:

Cant wait to see the HD3870 CF VS HD3870 X2 results. And compared to 8800 GT in SLi mode. The tested board has 1ns Sansung memory. Way better then that crappy Qimonda memory on the 8800 GT and GTS cards.
No one else notice this? (repost maybe?)

This card is sweet. It has four DVI outputs, two six-pin power connectors and the cooling seems more than adequate :)
Are you sure you can turn off one core?Quote:

ATI pushed the date back to the 28th. The reason why going around is so the card can launch with its new driver that has fixes and performance increases. Its possible it might be the quad crossfire driver too. NDA was also pushed back to the 28th.

I suppose if you have good case airflow it shouldn't be a problem, but if you feel the exhaust air coming from an 8800 series card you would realize just how much that could potentially affect case temperature, and in return CPU temp.
agree, a exhaust cooler design would be better.Quote:

MSI to clock Radeon 3870 X2 to 850MHz
For each GPU
We've learned that MSI will be one of the partners that will dare to overclock the Radeon HD 3870 X2 dual chip graphics card. Our sources have confirmed that the card will work at 850MHz while the reference card works at 825MHz out of the box.
We are sure that some other partners will overclock their cards too and we were surprised that ATI could make it over 800MHz with these two 55nm chips.
When it launches tomorrow, the Radeon HD 3870 X2 will be the fastest card on the market, at least until Nvidia launches its Geforce 9800 GX2 cards.

I didn't get any caps but I did note that it was CPU limited at 1680 x 1050 resolution even in certain games, and even at 1920 x 1200 I think a few games CPU limited it. Seems like a lot of CPU work is done w/r/t this card's performance. They did say it edged out the 8800 Ultra and given its price point, ATI took the crown back for a bit. Also it beat the Ultra handily in certain games, barely in a few games, and lost in one or two comparisons (World in Conflict was one of them iirc, but it looks like CF has a lot of issues w/ that game).
Looks like it was pulled since NDA got pushed back a week + possible driver release til then!
Thanks for that bit of information zerazax. You wouldn't remember what cpu they used in their benchmark setup?
any manufacturer in their right minds releasing gddr4 3870 X2 ?
