[Kakkoii]

http://www.chiphell.com/2009/0807/93.html

RV870:
1600 SP
256bit
80 TMU
32 ROP

RV830:
800 SP
128bit
40 TMU
16 ROP




ChipHell is usually correct about this stuff.

Looks pretty long. When is this likely to be released?

 

[faxon]

would be great if it wasnt all in chinese so i could actually navigate the site a bit rofl

 

[Keysplayr]

1600. That's more like it.
And the R830 looks like some hybrid of a 4770/4850 (specs wise, not feature wise).

Yeah. Assuming it is GDDR5 then it meets the same specs as 4770 with 800 SPUs instead of 640.

 

[alyarb]

cool

 

[TurtleCrusher]

Looks like my next GPU purchase.

Thanks!

Would that also be known as a 4870?

I'm gonna wait to see what GT300 brings to the table. I don't think it'll be a quantum leap in gaming that some people infer from the rumored specs (512sp, MIMD, etc.) but more so for GPGPU which I don't really care much about. If they perform around the same then I'll get whichever is cheaper and at most I'd pay $50 more if one card is a much better performer (I'm losing interest in gaming so spending $350+ on a vid card is not so enticing anymore). And hopefully I can still use my GPU waterblock (unfortunately it's unlikely with any new nV card since it no longer works with the GT200 series).

 

[error8]

It's longer then 4870X2. That picture is surely screwed up.

No, the 4870 has GDDR5 + 256bit interface, this rumored spec of the RV830 indicates 128bit (and we assume GDDR5), its more like a 4770 with 800SP...or I guess a 4870 with a 128bit memory interface...

Although while specs may appear to be extremely similar, we must also consider these are also DX11 parts.

Assuming the clock speeds are where they need to be I would think this should out perform the 4870x2. Not bad assuming it's priced right.

If it's first on the market, in front of the GT300, it will surely not going to be priced right. Assuming it goes over 4870X2, it will probably cost a fortune.

That looks great! Let's hope for $299 price.

RV830:
128bit

This may be a problem.

Why? If it replaces the 4670 and 4650 cards, it sounds good.

Considering you can get 4870 1GB for $100-120, the RV830 better be close to 4870 1GB's performance with that 128-bit ram for MSRP <$149. Remember the day when 6600GT mid-range was launched outperformed 9800XT for less $?

I sure hope that there is some $199 RV8xx series card which will smoke the 4890/GTX275. Then ATI will have a winner.

 

[dguy6789]

With 128 bit memory, I'd expect this to be priced between $50-70.

 

[Illyan]

Who cares about the memory interface as long as it performs well?

4770 is 128-bit and is $100-$110. If the 128-bit 4770 outperforms the 256-bit 9800GT which costs $90, why should something that's even faster than the 4770 cost less than the 9800GT?

Don't dis 128-bit too much. This card might perform in between the 4850 and 4870 which go for $100 and ~$130 respecively, so reasonable pricing would put it $115. But we'll see.

Wheres the 850 specs? That's what I'm interested in.

 

[Jacen]

Could have sworn this was posted already a while back. Regardless this should be an exciting card and probably my next hardware purchase unless I nab one of those Intel X25-Ms soon here.

New info:
Possibly 384-bit memory bus on RV870?

That would be really awesome.

That is the second place I've seen so far mentioned 384-bit for the X2 part, Nordichardware 2, but they also say only 192-bit for the 5870. This sounds bad, but as others pointed out, if it still performs really well, then I won't care cause this will help keep costs down. Maybe the memory bus is not the bottleneck so why not?

i think he means 384bit for the 5870, 192bit for the 5850, 96bit for the 5770... 48bit for the 5650... The x2 model would be 2x 384bit.

 

[yacoub]

It's like pulling teeth to get ATI to give it a decent bus width. 512-bit would be even better, 256 is a bare minimum really. yes, we know they have GDDR5 to make up the difference, but what you fail to consider is that having BOTH would be even better.
