Im looking to get the 5770 or the 4890 for my build right now. I have seen all the test and benchmarks, and i've seen the 4890 outperform the 5770. I'm currently looking for a faster card, rather then features. I have heard that while the 5770 is not that fast right now as the drivers improve the card will match the 4890 or maybe even surpass it. I was curious to wether this was true, or even possible. Thank for all the help!!!! :)

It is hardly possible as it is bottlenecked by its 128bit memory bandwidth. There is no way to make it better when there is already a bottleneck on it.

HD5770 is a huge fail of ATI. However, HD5770 has better CF scaling and so it would be the better choice if you are considering CF in the future.
 
I agree with the above. Improved drivers can increase performance, but ultimately it will be restricted by the 128bit memory bandwidth.

The HD 5770 is not a bad card as long as you keep your expectation reasonable. I will probably drop a HD 5770 into my HTPC for occasional gaming on my HDTV when I get tired of my 9600GT.

Well it probably will in a few, here it beats the gtx285 in some games, mostly older ones that would benefit more shader power.

There is no 'bottleneck' occuring with this card, it is what it is and at 3 times smaller than a 285gtx it certainly isn't 'huge fail' under any circumstance.

am almost tempted to take back what I said about it rocking past the 4890...

Know I saw those kinda benchies somewhere as was interested as my bro bought a 5770 recently and was impressed to see it beat the 4890 by a good amount.

Does beat the 4870 in a lot of tests though.

Wait a minute....just wait a minute.
I was ragged hard last week for mentioning this fact about the 128-bit interface and was told that was a thing of the past due to it's ddr5 and other features.
Say it isn't so!
My 7600GT could never outperform an X800XL and this was just 2 1/2- 3 years ago. It was like yesterday to me.
Oh, pipelines. Can't we squeeze just a bit more ketchup through the cap?

Thinking that a newer card should beat any older card is like saying that the 2010 Honda civic 1.6 should beat the 1989 Ferrari because it is newer! It is a complete ignorance.
the HD5770 is equivalent to HD4770 and not to the 4890! and it surpassed the 4770 in every test so it is NOT a fail nor a breakthrough, it is where it should be!

Gosh, AMD fanboy! Go read HD5770 review and every review I read so far regard it as a failure.

Its price is on par with HD4890 but worse than HD4870 in row FPS. What a great success!
 
OK to play devils advocate here and maybe get an actual answer this time.
How does it actually work then ? How does the card go about putting the info through the interface ?

What for example is the usual size of any given oh say texture, that would be put through ?
Or in other words would a 128bit card cause a situation where info would need to be split up to go through it ? If so this causes latencies dosent it ?
Is it just that a 256 bit interface can push more chunks of info through at a time, you would think it obviously can but you cant take anything for granted with PC's can you

So does a 128bit card just ram it through 128 at a time and its just a case of the speed of the ram canceling out the differance or what ?

I have seen this explained before and some don't agree but it makes sense.
Last generation....New 5 series gen
4890....58xx not released
4870....5870
4850....5850
4770....5770 *both 128bit gddr5*

Also the cards were released in a different order. Prior gen, 4850,4870,4890, this time
they worked backwards 5870, 5850, 5770. this generation is 35% superior up and down the line to its true predecessor.

edit: its the pricing of the 5770 when compared to the now lower prices of the 4 generation that people have higher performance expectations.

We can expect a 5% increase in performance as drivers mature. I doubt they will be able to pump enough juice out that.

@ magneezo

You were probably told that because the HD 5770 has a limit in potential when talking about over clocking, or at least pushing bandwidths higher. The memory bus with stock settings does not become a bottleneck because the card was never meant to be as powerful as the 5800 series. It was meant to compete with the 4800 series while providing DX 11 which is what it is doing.

As far as price goes it's a pretty good deal. Remember the HD 4850 HD 4870 and HD 4890 all had $200+- price brackets when they first came out. The HD 5770 cards are coming out at $165~, so keep that in mind.

REVIEWS:

But we don’t have that luxury with the Radeon HD 5700 series. The value of the 5770 in particular is clearly not going to be in its performance. Compared to AMD’s 4870, it loses well more than it wins, and if we throw out Far Cry 2, it’s around 10% slower overall. It also spends most of its time losing to NVIDIA’s GTX 260, which unfortunately the 4870 didn’t have so much trouble with. AMD clearly has put themselves in to a hole with memory bandwidth, and the 5770 doesn’t have enough of it to reach the performance it needs to be at.
From Anandtech: http://www.anandtech.com/video/showdoc.aspx?i=3658&p=14

If you belong to that group and are looking at “Radeon HD 5700-series,” expecting a big step up in performance, even the 5770 is a disappointment. After all, if you own a 4870 or 4890 already, that card is faster in today’s games.
From TOM Hardware: http://www.tomshardware.com/reviews/radeon-hd-5770,2446-17.html

PRICE:

XFX HD-487A-ZWFC Radeon HD 4870 1GB 256-bit GDDR5: $169.99

XFX HD-577A-ZNDC Radeon HD 5770 XXX Edition 1GB 128-bit DDR5: $189.99

HD5770 is worse than HD4870 in most cases and still cost more.

How can you say its Huge fail. Bing it and you will see it has received so many awards. Just because you feel or believe it, you should not continue to pass on your false beliefs.

Looks like you are seeing the whole picture through those "two" words. I would suggest you also read user reviews and not only depend on the site reviews. The site reviews are based on various parameters and comparisions.

I can also post so many links where it has received awards. So stop spreading your beliefs on others and downgrading such good cards.

as kikireeki mentioned already: "the HD5770 is equivalent to HD4770 and not to the 4890!" or 4870

The 4870 is replaced by the 5870 etc

The older 4870 (seems very old now) and 4890 are sold cheap to clear stock so are good value - bringing them into the 5770's ballpark (at least for the 4890pricing)

The 5770 does beat the 4870 in quite a few games now anyway.

That the 5770 is competing well with the 4870 shows some decent progress :)
