I thought the 4850 was a GDDR3 part only.

The 4870 I saw listed as supporting both GDDR3 and GDDR5. I hope that AMD does differentiate between the two since it looks like the GDDR5 parts will have something like 80% more bandwidth, so I imagine in certain instances the performance will be much different between the two 4870's.

IIRC.

ATI will be putting our 4850's in GDDR5 configuration only and giving its vendors the option use GDDR3 instead.

4870 will be GDDR5 only.

I thought it was 4850 as gddr3 only and 4870 as gddr3 or gddr5. that makes more sense anyway, b/c you would have a 4850 with gddr5 most likely be faster than a 4870 with gddr3.

 

[taltamir]

but we both said that we heard there wouldnt be ANY GDDR3 4870 parts.. only 4850 will get GDDR3, sometimes. Not the other way around..
Ofcourse this is all rumors... And really, since the chip can do 3/4/5 3rd party companies can choose to assemble any combination there-of.

I just put in a pre-order with free 2-day prime shipping, just in case it's good... got 8800GT 512 SLI at the moment, really looking for the 4870.

 

[taltamir]

i am really tempted to put in a pre-order, not because I want to use it (i will probably be using a GTX280 or a higher end, GDDR5, AMD), but because I figure if the price ends up rising sharply (if, for example, the GTX is a bust), then I could turn it over for a nice profit on ebay and still buy myself a 4870 / 4870x2.

 

[dennilfloss]

Aww, the Ferengi spirit still flows strong on AnandTech.:laugh:

 

[taltamir]

I thought about it... and i decided against it... while it COULD net me a fair amount, it will be too much time wasted for the money gained. Unless I order multiple units, in which case I might aswell open an ebay/regular store, and order an entire pallet of the things at dealer price.

And I have many pressing things I need to spend my time on. And things that could potentially earn me much more money.

 

[unr3al]

rofl @ Inq credibility...

I haven't considered them credible since as far back as I can remember...

 

[dennilfloss]

Volt mod for those so inclined.

They're on the stick over at Xtreme Systems. Not yet released and already a volt mod!

Damn these cards look promising. I've been a green team fanboy for a long time. I'm seriously considering CF but want to see good benchies. Can't decide on 4850 or 4870's...

Just to make sure you understand, those are GDDR3 HD 4850, not the GDDR5 HD 4870 that they have for sale.

 

[taltamir]

yes, not very appetizing when you know there is something much better, eh

These XS guys are awesome :evil:

So maybe you can buy a 4850 for under $200, then mod it and OC to over 1000MHz, that should beat the GTX280 that cost over $500. Not a very bad deal

 

[ChronoReverse]

You're not going to get 1000MHz from a 4850 on air

 

[unr3al]

We will have to see about that. There are rumours of the RV7xx cards being extremely overclockable...

 

[Foxery]

If they had that much headroom on standard air cooling, ATI would have released them there. Those guys at XS tend to have water or exotic cooling solutions. Check all sigs in that thread who have phase-change and liquid nitrogen.

 

[chewietobbacca]

4850 cooler probably won't allow you to get that high of clocks, though with aftermarket cooling 800 might be doable

The ATI CCC only allows clocks up to 700 MHz for the 4850 and people said that 700 was "easily" doable so there might be more headroom

@Azn: Some of that numbers look very... strange to me. For example the 3DMark06 numbers - hey, I almost get 12000 Points with my overclocked 8800 GTS 640 (G80) and an E4300@3,1GHz!!! (For real and not in my dreams)

It would be nice if those numbers could be backed with some test system specs.

 

[Janooo]

800 is becoming more and more official.

The die size of RV770 will be about ~57% bigger. We are looking at a ~300mm^2 chip (could be bigger). So im more inclined to believe that this GPU will have 800 ALUs and the extra TMUs also.

 

[ronnn]

Looks to be out on the shelves soon. Maybe before the 25th.

 

[semisonic9]

Well, and I'm still confused on this...but is it really 800, or just a multiple of a lesser number that acts like 800?

Any news on the official release date?

you have 160 groups of 5 shaders. 1 is strong and the other 4 are weaker.
