R700... 2Gig of Memory :)

[deathman20]

Comes in late August

We just got a final confirmation that R700 uses two RV770XT GPUs and that it supports massive 2GB of GDDR5 memory.

Naturally, the card uses 256 bit memory interface and it looks that the card can ship in last days of August.

ATI used the codename Spartan for R700, as someone got hot for the movie. At this time, there are no talks about any clock speeds but the brand should settle at Radeon HD 4870 X2 area.

We will confirm this as soon as we can.

So is it true? One can only hope and if it is hot damn....

[Shiggity]

Fudzilla!

Still believable though.

I'm going to need a 2500x1600 monitor now!

[deathman20]

Still believable yes even coming from them.

Maybe they where saving all the 1Gig modules for this card since surely it could probably use it alot more than the other ones if there is a video memory hinderance.

[flopper]

and the card is for 2560x resolution and ram is required.

[vixro]

Lol the Spartan card.

Makes me think of This is Sparta, techno remix from youtube.

Look true to me ...

We've seen it take it all off recently and now the Radeon HD 4870 X2 has a little something for all puritans out there, two more shots of it looking lovely (BEd: You do realize you're talking about a graphics card right?) in black and equipped with the reference dual-slot cooler. Codenamed R700, the upcoming PCI-Express 2.0 and DirectX 10.1-supporting card has two RV770 GPUs connected via a PLX bridge card that offer no less than 1600 Stream Processors.

Said to be available in both 1GB and 2GB versions, the Radeon HD 4870 X2 will utilize GDDR5 DRAM chips and will require extra power through two (one 6- and one 8-pin) PCIe connectors. The card is expected to be launched next month and cost $499.

Sweet, only $500? Hope they can build them fast enough. Also hope they don't stick with the first generation PCIe bridge like 3870X2 :(

[thideras]

When they say "2gig", do they mean that each core has 1gb or 2gb?

I'd imagine it's like every other dual GPU card, 1GB total or 2GB total.

[deathman20]

1Gig per core for the 2Giger.

Also there was mention of the 512Meg per core for 1Gig total. But taht was only DDR3 which sounded like was going to be the $499 price point.

But fast too... 778Mhz on the core stock, forgot what I saw the memory at on the GDDR5 version but it was faster than the 4870 at stock that is.

[Badbonji]

Will it be able to use all that Ram in CF as in the whole 2gb, or is that only in dual monitor where each chip uses 1Gb per monitor?

[SuperDave1685]

From what I've read, I believe each chip will have 1GB to itself... I think

[deathman20]

As in all dual card + setups currently. Each core has its own ram that can only be used by that core. But as well you will only use up as much as the primary video card uses, if Vid card 1 for instance uses 325meg, vid card 2 will use 325meg as well since its more or less acting like a mirror.

[Chaos_Being]

Wow and I was already interested as is...looks like I might be going back to an ATI card for my rig again once this comes out :eek:

[n3xu5]

It's literally killing me but I am currently building a new rig thats watercooled in a rocketfish case. I want to buy everything now and go-go-go, but the smart thing to do is to wait on this baby! *cries*

[Codeman05]

I'll take 2 :D


I was hoping for a slightly earlier release, but I can make it another 6-7 weeks I suppose.
Curious to see what the GX280 GX2 (or whatever they decide to call it) will do, but I'm guessing it will be significantly more $$.

[netmask]

And what about dueling with GTXs? I think there will be a market overtake.

[El<(')>Maxi]

A black PCB from ATI, what is the world coming too :D

Anyone know something about the rumored differences that suggest this card will be faster than a pair of 4870's?

[Cheator]

So we can expect a post from RB about how much this card sucks by about the end of August?

Looking good, I might save up for one!

[Brolloks]

What a monster, can't wait to try 'em out :D

Well sites have been saying the core speed is 778 and memory is faster as well. So overall default speeds its will be faster than 2x 4870's.

[Shiggity]

ATI also plans on bringing out a 4850x2 as well, which will probably have just 512MB of GDDR3 memory per GPU. 400$ maybe?

That would be nice card to do some CFX with

The current theory going around on the net is that the 4870x2 is 10-15% faster then crossfire 4870. Some of this is related obviously related to the difference in clocks if what we are hearing about the 4870x2 is truely final. However that can not fully account for the 10-15% difference alone.

Currently most of the speculating surrounds the crossfire sideport in the rv770 chip that is not enabled on the other 48x0 cards but should come enabled on the 4870x2. This allows the two cores to communicate faster and more often then they conventially can. Also this (read the anand article) along with info on the new plx chip* leads to some speculating that memory can be assigned more dynamically between the chips. However that leap of faith is skechy at best and I personally think that is only wishfull thinking.

something else to note is that the new plx chip has a longer processing time so microstuddering might get worse but thats an entirely different topic

[Chaos_Being]

Yeah, I'll be interested to see if people experience microstuttering with this card. Knowing my picky eyes, I'd notice it and it would drive me nuts.

Also, has there been any speculation on PSU requirements? I'd be miffed if my PCP&C Quad 750 wasn't adequate any longer :/

[dealmaster]

I'm sure it will be, my HX620 is plenty to power 4870CF so I'm not even considering upgrading it for the 4870X2.

[Chaos_Being]

That's what I thought, thanks for the confirmation though :)

but these new 4 series share the memory i recall reading, it isn't used like in the past where everything is doubled in ram for each card, that is 2G accessible by each core.

Nope they aren't sharing memory. There still using a bridge chip which eliminates the use of sharing memory. It would be nice and surely that would remove a lot of bottlenecks between the 2 cards but sadly nope :(

It sounded like ATI was working on something so maybe we'll see it in the next gen or gen after that. If they want dual GPU's more or less to become standard they will be working tword it.

Look true to me ...

:( doh! that sucks, i was pretty sure it was a go :(

Hey at least they are doubling the speed between the 2 cores. So instead of the 2.5Gig of information a sec it could transfer its now up to 5.0Gig. Not nearly as fast as the memory but hey its definatly an improvement.
