[FUD]RV790 has different pin layout

A truly new chip

RV790 cards are shortly going into production and we have learned that RV790 Asic doesn’t have the same pin layout out as the RV770.

At first we believed it's the same chip, just tuned slightly faster, but then we got an information that RV790 is a new chip with RV770 fundamentals done better.

The PCB and the pin layout will be different for RV790 and we also heard that the new board will have two power connectors, one 6-pin and one 8-pin, but this doesn’t come as surprise as 4870 has the same.

The RV790 chip is not pin compatible with RV770 boards, so partners will have to change the layout of the boards to accommodate the new chip. Radeon HD 4890 is the most spoken possible brand, but knowing ATI's current GPU management, this can change in a blink of an eye, at least until the boxes are produced.

Hmm..Did they add the extra "Bandwith"?
I forgot what its called..So if it is really 20% performance increase,will it match GTX285?

And quote it properly.
That doesn't have to mean a completely new architecture - otherwise AMD would have just given it the HD5k series. A different layout could mean a more efficient layout with less pins or a more stable layout with more pins.

No one is implying a completely new architecture, just a more major revision than a new stepping.

Manufacturing process, and even number of functional units (ROPs, TMUs, SPs), are probably identical. That doesn't mean there is not plenty of room for change.

Indeed why would there be another major architecture change when the RV870 will be it. The RV790 appears to be a refined RV770 intended at squeezing as much performance and power out of the RV770 as possible.

Wait.

"6 and 8 pin, like the 4870"

I only count 2 6 pins on mine... Probably just a typo. Regardless, looks like AMD has another great chip on their hands. Glad to know it isn't just a simple rebrand like nVidia seems to love doing.
6 and 8 pin just like a 4870? Do FUD authors even proof read? They're articles are always littered with typos, mistypes and grammar errors.

Anyways, can't wait to see what these chips can do and see if they can actually compete with Nvidia's top end in a "single" chip solution.

These forums are getting absolutely ridiculous. The GTX280 is significantly faster than the 4870 1GB. It's usually close to the performance of the GTX260, typically slightly below.

The 4890 or whatever it will be called may be as fast or possibly a tad faster than the 260-216, which is why nvidia is preparing the GTX275. The 4870 was never meant to compete with the GTX280, that would be the 4870X2.

This is confirmed multiple times by AMD's own marketing slides.

This is an absolutely ludicrous argument and I have been observing that the quality of information on OCN has been rapidly dropping off as of recently.

I cant wait to see how this stacks up


I'll have to get one.

Expect full d3v0 benchmarks comparing this card versus the GTX 200 class cards

With no panzy 3.2ghz processor speeds like half these review sites hehe

Are you sure?

Theres going to be two different 4890 1gb version, vanilla and OC and for all we know Nvidia is scrambling the GTX275 just to compete with the vanilla version and 4890 OC is going to compete head on with GTX 285.

First off, WE ALL KNOW THE 4870 WAS NOT MEANT TO COMPETE WITH THE 280!!
That's just common knowledge and plain common sense.
The 280 is GENERALLY 20-25% faster than a 4870, this has been proven time and time again with multiple reviews. Don't ask me to site them because I'm sure you are more than capable of finding them on your own.

The 4890 is stated to be up to 20% faster than a 4870, which if this holds true, it will put it right around the same performance level of a 280 and possibly a 285 IN SELECT GAMES.

The only quality that I've noticed to be dropping off are the quality of your posts. You seem like a smart guy and able to hold an intelligent conversation but the conceited and condescending tone in your posts have been becoming more and more apparent. You try to come off as the sole voice of sanity in these threads and its really not called for. If you think the "quality" of information given by other members of OCN is not up to your standard, then simply stay out of OCN.

Yeah thats why.If it is a really 20% performance boost(RV790) im sure it should be on par with GTX275 or perhaps higher or lower.

it's called fanboyism and he's really into it.
he'll be biased no matter what


now you just wait for the new ati cards that will have much improved folding perfomance.

Wow...does Fud like to post the same article over and over again. They stated this already last week when they retracted their earlier statement.

For some. Unfortunately, there seems to be an increasing number of people who think that the 4870 is right on the toes of the GTX280 and that the RV790 is going to compete with and possibly take the single GPU crown from the 285.

And you must realize, most of the rumors about the RV790 have been coming from FUD and Inq. Oddly, you don't see much Fud or Inq bashing when they have pro-ATI/AMD articles. Funny, isn't it. Don't take this as fud/inq bashing though, I'm just pointing out an interesting tidbit of information.

Secondly, you can bet that the 20% figure is, as with the Phenom II, an up to figure, not across the board. The architecture remains the same, only the clock speed has been increased, so you can expect the performance highs and lows to be roughly the same.

It's Fudzilla... Much like Inquirer and Kotaku, it's a typo when something is expressed properly.
