the chip information themselves are of course stored in database and are read through device id

How is it suppose to know the size of the interface?

What we know so far:

1- Same PCB (or at least very similar) as HD4870;
2- 2*6 pin connector;
3- 240Mhz (!!!) idle speed (I guess the rumours about the PowerPlay revision were true)
4- Same cooler
5- ATI OC Utility shows a max overclock of 1Ghz;
6- It's called 4890 and not 49xx.

Performance figures and design changes are only guesses right now.

And here's the first boxart:

I found it in Fudzilla. I don't know where they got it, though.

I'm doing it... 3 x voltmodded watercooled 4890's @ 1100mhz core clock here I come :D these things are gonna be BEASTs

Not the same cooler, it is an updated cooler.
Suppose to be a 3 heatpipe HS vs the 2 heatpipe heatsink of 4870.

From what I could see, the idle temp was 59°C at 24% fan speed. What's the 4870 idle temp at that fan speed anyone? Should be an indicator of how much better the powerplay is working.

so same pcb or similar? will be waterblocks from 4870's fit here?

and still no any info abot x2 :confused:

I can see 16 ramdacs on this 4890 which means 4870 FC is a nogo....

I am utterly horrified to see the memory is still not affected by Powerplay!
It's just useless to slow down the GPU speed as memory is the idle powerhog on these cards.

I don't think you realise "RAMDAC" has absolutely nothing to do with the memory you see on a video card.
And, there's only 8 GDDR5 chips on those cards...

ugh yes sorry, It just seems more distinguished in that pic than the 4870... it is the same.

that said I have just compared and the mem/gpu area is the same. but the PWM area is vastly different.

For the ATI Guru's: Will the HD4890 X2 follow the single GPU sister launch on April too?

Looks like the first rumours were true...we'll see the 850 and 950 clock versions at $199 and $299.

I'm still waiting for the ace in the hole but have a feeling ATI may have us wait a tad longer to show that.

not in april for sure, june/july at the earliest IMO.

the 4890x2 when it comes will not be a friend of the average user... it will be expensive and it will be the 295 killer for benches alone.

Here's something fresh from Asia, with love. Popular Chinese site Coolaler is once more first to show pics from an yet unreleased product - the next generation ATI Radeon HD4890 video card. The card below is equipped with single RV790 GPU clocked at 850 MHz and 1 GB of GDDR5 memory clocked at 3900 MHz. It has full DirectX 10.1 support and is CrossFireX ready. Apart from that, all other distinctive features can be seen from the pictures. The Radeon HD4890 is set to be released after April 6th of this year.

just did some more side by side comparison and the gpu area of the 4890 looks markedly different than the 4870....

oh no, so sad
if so what to choose for watercooling - wait for july or buy two 4970 using two waterblocks?

Thanks for the reply Sniipe, you bet the 4890x2 will be a monster just judging by the 4890x1 power requirements.

I will keep my old faithful 4850 and wait till July then. :up:

I cant say for sure, but if it beats the 295 (which it will) it will be priced accordingly

Yep it looks VERY different. The shader configuration is different

Will there be two different versions of 4890x2?

AS in OC and Vanilla just like with 4890.
