ATI Radeon HD 4000 Series discussion

[ORBR]

It would kill any demand for a 4850X2 as well. I'm sure ATI would prefer for that not to happen.

Unless the X2's this generation scale obscenely well all the time at least, that's a nice pipedream

or maybe there's no 4850X2 at all...


other scores... the 280 seems heavly powned..

GTX280
SM2=5439
SM3=4653

4850 CF
SM2=5770
SM3=6109

Possibly. I'd imagine some partner would make one though. Even if ATI doesn't lay out a design for one themselves. I mean, Asus made that crazy 3850X3 Trinity Super Ultra Insanity FTW Edition card

You know the one I'm talking about, with 3 3850 GPU's on one big board that you have to watercool.

Granted, I doubt it will ever actually be sold to the public, but the idea of a 4850X2 is a little less weird. So who knows eh?

Best name ever.

and 9600 Matrix
way better than longbow chik!

anyways, red team needs the X2, at least for pub sake, and I think they know that....

OH I just think that trinity was only a try.. to prepare the card for 3-way with different GPU's

prepare yourself for Asus HD4850X3 Trinity

2 times faster than 280 with almost same price (or little less)

According to GPU-Z, this can never be HD4870:

800mhz clock (GPU-Z displays 750)

memory clock should be 1800mhz (3600mhz effective, afaik, it's named GDDR5 and not GQDR5)

Bandwitdth is 57,6GB, so it is not GDDR5 for sure...

It's an HD4850 overclocked to 750mhz (maybe bios edited, )

This is, in fact, very good news, HD4870 can only be better than this, which is great.

Are you going to be able to use crossfire X and say put the 4850 and the 4870 x2 together?

You can already do that with an HD3870X2+HD3850

[Ral3l3it]

Nice but we are going to be limited to only using the 4000 line we can't do like a 3870x2 and a 4870x2 in crossfire X right? Also how much better is the 4850 going to be over the 4870 I can't decide if I want to get a 4850 and then a 4870x2 later on and just crossfire them.

I tried a 3870X2 and my 4850.it was not even close to working, no second card seen no option for x-fire etc. so I PICKED UP ANOTHER 4850.....

I really don't know if that is going to be possible, but my guess is not. But it could be, one never knows for sure, so you just have to wait to see if it is possible or not

I don't understand this. They say this is suppose to be HD4850 but GPU-Z shows some really weird data. Clock is much faster and it shows GDDR5 yet bandwidth is out of whack. On the other hand score is much higher than default HD4850.

I thought HD4850 will only support GDDR3. Unless of course they really meant to say this is HD4870.

Smells like fake to me. Or at least very strange.

Actually I believe it IS the 4870

The 750MHz core cant be reached by CCC right now so unless they've already done BIOS editing, it has to be the 4870 since thats the core clock for it.

Also, 4 x 900 = 3600 MHz which is the stock mem clock of the 4870 as well. I know its not supposed to be QDR, but read the GDDR5 whitepaper by Qimonda: http://www.qimonda-news.com/download...whitepaper.pdf

GDDR5 has a lot of differences so it might not be properly detected by GPU-Z anyways. That might also be why Vantage crapped out and couldn't give a proper score since it might not be detecting the card properly.

However those test results are ridiculous for the card... if it truly performs at that level, then the 4870 might be closer to the GTX260 and 9800GX2 than we thought.

Actually, the only differences between HD4850 and HD4870 are GPU clocks (625mhz, 800mhz respectively, IIRC) and memory type (GDDR3, GDDR5 respectively)

It also sounds very strange to me too, I don't know what to think, but my guess is its fake...

This is the other side of my thinkings, guess I'll need more facts to convince me

BTW, wasn't HD4870 supposed to be 800mhz core clock???
