ATI Radeon HD 4890 1 GB GDDR5 in Pretty Pixels

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 HD 4890 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 HD 4890 is set to be released after April 6th of this year.

Thats cus it is effectively just an OC'd 4870.

Yay, even more heat/noise issues! :rolleyes:

looks just like a 4870
If ya have one take it out and compare it. The board might change.

from all accounts its is just the same as a 4870 just tweaked to allow high clocks

The backside of the PCB's look almost identical with the exception of the power connectors.

From what I have read the only thing they had to change PCb wise was going to a 5 phase power setup to handle the increased demand of the higher clocks.

If people had issues with heat on the 4870's and heat, I hate to think what is going to happen with this one.

What can AMD do? Get RMA's on people thinking they bought hairdryers? Or overheating cards?

More performance might mean more power consumption with ATI. Please prove me wrong but we don't know until we have reviews.

It will mean more power consumption, the RV790 is the same as the RV770 other than a few clock and possible voltage tweaks. So I can guarantee it will use more power, which is also why AMD had to up the power phases to 5.

I hope AMD brought OCing prowess to these cards.. anything less than 1Ghz on the core does not warrant another release IMO.

If these are going to suck the power I'd hate to see what a 4890x2 can do(You know it's coming).

increased heat means that amd will have either beefed up cooling or increased fan speeds, i go for the latter the increased speeds

means more noise and i know what it can be like unless you have a quiet case without to much holes in it (mines has those top fans so it gets noisy)

After reading some of the posts in this thread you would think that nvidia's video cards didn't get a bump up in GPU clocks, etc. :rolleyes:

It's just so common from them though.

For ATI to OC and rename/re-release a GPU it had better be worth it (clock wise) or its just a lame marketing maneuver which (IMO) is best left for the green camp.

Maybe because Nvidia clocks were lower in the first place, which meant cooler, quieter and less consuming cards.

I think folk are a bit more open minded then that. I read some of these posts to imply that the 4890 is a next gen card when in fact it's a simple refresh of the RV770. Because it's a refresh another name is appropriate as long as it follows it's curent line of products IMO. So, I really don't see the issue here. Maybe it's because I don't consider this a next gen card offering next gen performance :slap:

That makes no sense and is neither here or there to my post. In all, we either have to wait for:
A. Some insider information
B. Actual review of the card

It's hardly "next generation", but it should be able to reclaim the title of world's fastest single-GPU card - for now.

The 4870 never had the title of fastest single GPU card. The GTX280 held that title until the GTX285 was released.

Let me just say this, I was really glad to get a XFX GTX 260 216 Black Edition months ago and everytime I see a revised card come out from NVidia and now ATi (*shakes head*) it ensures me that I made the right choice at the time. All these revamped, renamed, re-released cards is getting crazy.

I myself was hoping for a few more shaders.

I meant that people may not be so concerned about Nvidia clocking their 55nm cards higher, because those ran cool and quiet and consume significantly less than the Ati counterparts for the same performance. But Ati HD4870's with reference cooling, the same cooling we see here, already run at high 80's - low 90's so it's a matter of concern. We should wait until reviews? Of course, but if we don't have to talk about the cards until reviews why post any news then??

I'm yet to have any issue with any 4850/4870..
I think people are trying to put them in their Dell's without any air movement in the case that's causing the issues.

Can't count the times I have seen 3850/3870, 8800 and 9800s in small cases with no air movement and wonder why after an hour of gaming they start artifacting.

Hopefully RV790 brings enough tweaks to an already great RV770 to warrant excitement. The already impressive clock speeds are a nice start, but I want to see real pricing and overclocking performance.

If these are just binned RV770 cards, and I think they are, then I wouldn't think they would have much headroom left, which would be a real shame.

Hopefully this is a new revision of RV770, which even though they are the same on paper, is superior in practice. Similar to the B3 to G0 move Intel made.

It used to be that cards overheating in cramped cases wasn't acceptable. Video cards were expected to work, even in the crappiest of airflow situations. Which is why I sure people still expect to put the beefiest card possible in a case with no fan other than the PSU, and have it work without issue.
