Massive demand expected by AMD for its latest graphics card

ATI, the graphics division of AMD, has launched the Radeon HD 4890 video card exclusively with 1 GB of GDDR5 RAM.

The RV790 is not just an overclocked RV770. DailyTech noticed the RV790 chip was slightly larger than the RV770 when we acquired a reference board several weeks ago. It is a new respin of the original silicon, with retrained and rearchitectured power paths for greater power efficiency. ATI engineers also used decoupling capacitors in a decap ring to increase signal integrity.

All of this enables higher clock speeds. While the Radeon 4870 has a core clock of 750MHz, the Radeon 4890 runs its core clock at 850MHz. The standard GDDR5 runs at 3.9GHz effective, and provides 124.8 GB/s of bandwidth. Several ATI graphics board partners will be launching models with core clocks running at over 1GHz using improved cooling solutions.

Power consumption is also greatly reduced. The Radeon 4890 board consumes approximately 60W at near idle loads, such as when displaying 2D graphics or working on Word or Excel documents. This cuts powers consumption by a third from the Radeon 4870, which utilizes 90W at idle.

On the flip side, maximum board power is now rated at 190W with the 4890, an increase of 30W. This is due to the higher clock speeds of both the GPU and the GDDR5 memory.

DailyTech has performed a few basic tests of the Radeon 4890, and our results show a 10%-25% performance improvement, depending on the game. The drivers in the box will work best for now, until the Catalyst 9.4 drivers are released later this month.

We have received word that there are over 50,000 Radeon HD 4890 cards already in the market. Several retailers have already sold cards to anxious fans ahead of today's launch date. The cards themselves should sell for no more than $250 at stock speeds, although we expect prices to drop slightly in a month's time. Some partners have also said that mail-in rebates for $20 will be available.

AMD recently tried to lower prices on its Radeon 4870 and 4850 cards, but its board partners believe that the performance of the Radeon 4870 is too good to lower prices further. The 1GB version of the Radeon 4870 is now selling for around the $180 mark, although it may be available for less with a mail-in rebate partly subsidized by AMD.

The primary competition for the Radeon HD 4890 will be NVIDIA's GeForce GTX 275, which is also priced at around $250. However, there will be no retail availability until April 14th, when it was originally supposed to be launched. Even so, our sources say that NVIDIA will not have the volumes that it needs to meet demand, which may end up raising prices.

Further out, ATI will be launching its first DirectX 11 parts in late summer. Some consumers may be tempted to wait for the next generation of cards with an all new architecture, but they will launch at higher prices. If you're looking for a high performance single chip video card, the Radeon 4890 may be your best bet for the next five months.

UPDATE: ATI has confirmed that the original information we received was incorrect, and the RV790 does indeed have 959 million transistors.

I've got a 4870 512M now, from the numbers I'm seeing, the 4890 doesn't make sense for me as an upgrade. The extra RAM would be nice, but it only makes a discernible difference in a few titles.

I think I'll wait another 6 months or so for the next gen 40nm high end chips.

Although, if the 4890 drops to around 180-ish, I may be tempted to sell my 4870 and pick one up.

Not quite, 30W 24/7/365 is $30/yr or less. If you're going to upgrade from a 4870 to a 4890, I don't think you're the person to hold on to the card long enough to make up the difference.

It doesn't really matter I don't think. The 4890 and 275 are parts that are likely to entice those on older graphics that waited rather then those of us who are already on the current generation.

I see price drops though all around because that's what will really spur people to buy under the current economic conditions.

Why do most of the ATI cards run so HOT? They require ultrafast and LOUD fans to cool them and TWO slots. Not everyone wants to play games. I'd like to find a new ATI PCI-Express card which does not use a fan, has 2 DVI monitor outputs, 1 S-Video output, uses only ONE slot, and plays DVD's ported to TV.

That's what I mainly use my present ATI video card on this older system for. The picture is excellent, so good I can actually pause the DVD and surf the 'Net if I wish. Because it does not have a fan, there very little noise while I see my DVD's. Not everyone is a gamer. ATI has overlooked us in this market segment.

BTW, because video card fans come with the card, card makers usually install the cheapest sleeve-bearing fans they can find. High speed sleeve-bearing fans usually only last a year during heavy use so forget about keeping your card "for 5 years." LOL.

The 4600 series has been around for a while. There are also passive solutions that don't use cooling fans, but the chip runs hotter as a result.

The $250 market segment chooses performance over cool performance. A passive solution is possible, but most people would rather have a dual slot solution with higher performance.

I really looks like 4890 is just an overclocked version of 4870... both share the same core, the same number of processors, and the same amount of filling rate.

IMO its really not worth the money to upgrade to a 4890.

RV790 is an updated core that allows overclocks to 1ghz in many cases. http://firingsquad.com/media/article_image.asp/242...

But I agree, if I had a 4870 I wouldn't upgrade either.

I have a 3870 and I think its going to be enough to carry me through DX10/10.1. Just like my 850xt carried me through the end of DX9.

I'm going to sit it out until DX11 cards arrive. Of those few games I cant play at my monitors full spec they will be $10.00 or less when I get the DX11 card. I just cant see upgrading to another DX10 card when DX11 will be out soon enough.

HardwareCanucks managed to overclock theirs to 1GHz on stock heatsink. Maybe the guy got lucky, but still pretty impressive.

He thinks it can go higher, but unfortunately Catalyst CCC currently limits core clock speed to 1GHz.

I can only get 805 out of my core on the 4870 so yeah that's rather impressive. (Again though for those of us on current gen cards it's not a compelling reason to upgrade)

I think that you will do well with your card for quite a while.

With 4870 installed there is no need to upgrade just yet.

That performance chart is obsurdly misleading. A quick glance at the chart implies that the 4890 is more than twice as strong as the nvidia gtx 260. But if you look at the actual scale of the chart its only a 25% increase. Some actual numbers to back up their claims might be nice rather than their arbatrary performance factor.

Furthermore the gtx 260 is $180, why would you want to spend $250 (almost 50% more) to get this card for 25% performance increase? I can see why they tried to skew the results of that chart, but they really shouldnt have shown it at all.

I am not trying to bash ATI by any means, but based on the performance specs put forward here this card isnt anything special. If it drops to $200 it would be a good bang for the buck niche card, but at $250 its a cash cow.

hm......

The Guru3d review you posted seems to be the exception to most of the other reviews I am seeing. Anandtech and HardOCP seem to be showing the 4890 being slightly better than the GTX270. With the 270 winning out at higher resolutions and the 4890 winning at resolutions below 24" in monitors.

Whoa!! You're totally right. I didn't get a chance to read all the reviews yet. Looks like i should have done so before I posted. Its really curious too see such a different result between these sites.

I generally trust Anandtech but it is very curious that their results from testing are so very different from the other review sites. Have to look into the rig they used for testing and compare to see if there what is up.

The temps are bothering me though. The GTX 275 is reaching 90 degrees under load. That's simply too hot. I would be concerned with the cards reliability, and that the added heat would affect the rest of my system. Not worth the worry when I can get a GTX285 for less than $100 more, and better performance to boot.

Right, that matters because people who spend $250+ on a video card will turn around and buy a 17" monitor with a 1024x768 max resolution.

4870 is 256mm2 4890 is 282mm2 due the architectural tweaks to enable higher speeds. Although some sites have posted GPU-Z screen shots confirming this none seem to have commented on it and most seem to be assuming that it is the improved VRM circuitry on the PCB that is responsible.

I think the OP has a point. If an article is posted, and readers make comments, DT should not republish the article in a way that purges the reader comments. It's disrespectful to the time/effort the reader invested posting them. And after all, a lot of the value of DT is contributed by comments posted by readers.

The comments weren't deleted on purpose. The comments were purged after the article was pulled to make corrections and was then reposted.

This is not an issue about silencing readers. As you can tell from the comments on our articles, we don't go around deleting posts -- we rely on reader moderation to handle posts that people find offensive/unworthy.

If DailyTech wanted to purge all negative comments, there'd be no comments left ;)

The decision was made by Brandon to pull the initial post. We will certainly take reader input into account in the future.

FYI, I had already rewrote part of the article to address some comments from AMD and readers. Those changes got lost when the article was pulled. You are not the only one who was inconvenienced, unfortunately.

I do hope you understand that ultimately, we were just trying to make the article better. Sometimes what seems comprehendable by us may not turn out that way, and requires more explaination. Sometimes we make mistakes; we will admit that we screwed up and fix it.

Every publication makes missteps; DailyTech's get magnified because our readership is so large.
