AMD 3870 X2 official specs!

looks neat. tho i guess we have to wait for the benchies.

So when can we expect to see this in stores?

Ok, I haven't posted in a long time now. I was reading this and with my 8800 640 I feel like I was living under a rock.

640 Stream Processors??? That is totally insane.

Well, I give up. I am going to only buy new systems at this point with each "revolutionary" game that comes out, that marks a new Game Engine generation, ex. Doom 3, Crysis, etc.

My next new system will be when then next engine AFTER Crysis is out. Then I will WAIT until an x4 or x8 Videocard of that generation can get 60 FRAMES PER SECOND 1080P or else I ain't buying nothing.

There. That tactic seems foolproof. I will never buy for a game again to be burned at sub-30 FPS gameplay. Lesson learned. Just blew 400+$ a few months ago for 96 stream processors now we are up to 640????

Live and learn.

Looks hawt. Although I'm sure my 8800GT will be fine for me until the generation that follows the 9800gtx. No thankyou to buying a new card every generation.

But this looks exciting for anyone about to build.

i like the design better than nvidia's dual pcb method ala their gx2 product but i will need to see benchies as to how it compares to dual 3850's and also if ati has better luck with qaud crossfire than nvidia had with quad sli.

Sure, 640 stream processors... yay.

Too bad it's crippled by a lack of RoPs and TMUs. (only 16 each per GPU so a total of 32 each for the x2, which severely bottlenecks all your pretty stream processors)

EDIT: Don't get me wrong, I'd really love one of these cards. I'm just disappointed in ATI for not improving upon a blatant shortcoming in their flagship product. Would 8 more of each RoP and TMU have really increased cost that much? I'm willing to bet the cost would have been offset by the reduction of the memory lanes.

you should be able to when the new drivers in january come out. need the right mobo of course, not sure if any are out yet.

That's getting out the marshmellows or hot dogs to roast on the heat output.

Now where was that add for a 1500wt psu?

Actually Hatman, I just read the last link posted by qwertycoptor. It says it can be quad-crossfired. PSU support is another thing...Jesus, where's that 2k PSU?

i think i need a change of boxers :T the ati fanboy inside of me is crying tears of happiness T_T...and here i was bout to go for a 8800GTS. but we'll see how the 9xxx series stands eh?

we'll see when it comes out, ati never has power at the start then they pull that ace outta nowhere, usually too little too late!

I said it CAN be quad crossfired, since it has 2 gpu's, but 4 of them cannot be used to make octo, just 2 of those cards for quad.

Np strangestranger sry 4 being so aggressive btw


Should perform just as well as 2x 3870's in xfire so have a look to see how well they do.


Tbh it should need a stupid amount of power... a single 3870 is rated 100watt so if its like the GX2 powerwise it should be less tbh it would be around 150watt for a single 3870x2. So dual ones of these will likely use less power than dual GTX's.

dam you just shot down all my hopes and dreams.... guess it's back to cutting myself

It should be under, since the 8800GT gets only 504 Gigaflops, and the 3870 is weaker.

thx good info

one thing guys it looks likes its 13-15 inches long it will fit in only a few cases

yes but that was dual pcb while this is dual gpu, they will have to fit them somewhere.

Benchies benchies pleeeeeeze! This means I'll be waiting even longer before I buy my new comp.. (I must have the longest lived 5900 card!).
Wonder if this thing'l get 40-50 frames per sec in crysis with eye candy turned up at 1000 by 1600???
Yipeee! (It's all good!)
Ryan.

As far as I know, crossfire-x supports "up to" 4 GPUs, so I would imagine it would work just fine.

EVEN IF these specs were real, I would really like to know if it even WORKS?!

my 3870s looks sweet in my rig..... but the crap doesn't work (in most instances).

/quotemsg]

640 stream processors is indeed insane, but if we look back to the SP of a 8800GTX and HD2900XT, the 2900 has
twice as much 320 compared to 128 on the 8800. When the results came did all those stream processors kill the 8800? Nope. IMHO I say when comparing today's DirectX 10 graphics the bigger the specs may not guarantee it will perform faster or better. It's all about the architecture.


BTW: I may be wrong on this, but if I remember correctly, the SP on Nvidia and ATi's cards are totally different.
For Nvidia's SP has 5 different task (forgot what they are) and each of these SP can do a different task at the same time thus leaving no SP idle.

For Ati, the SP also have 5 task, but instead of all of them working only one can do the whole work while the other four stays idle.

Now if that is the case then for every group of 5 SP in a AMD card and only 1 can do the whole job while the 4 of them are drunk. Then 640SP may not seems as much.

And am I a nv fanboi?
Nah, own a HD2900XT here.

I wish Heidi Klum was my room mate, and perhaps a couple million dollars to keep us company. I guess we all have to wait.

Ok, maybe for just a night or two. Got to have my fantasies, you know. Real life can be a drag at times.

this should work a little bit better than 2 3870s in crossfire as there is no crossfire bridge to connect the two which can cause slow downs and why scaling is so bad on SLi as it only uses one bridge.

in a PCI-e 2.0 slot it should scale extremely well in crossfire, as it could theoretically allow for each GPU to access x16 1.1 bandwidth in the same slot meaning there would be no bottlenecks caused by a crossfire or SLi bridge.

this should also help with the problem crossfire has in some games actually slowing down the FPS dramatically.

hopefully nV can come out with a similar solution to force ATi prices downward as a 2xG92 would beat a 2xRV670 in just about every app and game there is FPS wise making the ATi solution a price/performance king, and nV the raw performance king letting people choose for a price efficient or pure powerful system...

ahhh the joys of competition, how lovely they are for the consumer

Recently Used cars= ok
Recently Used girls= not ok

ewwwwwwww! =D
Unless you are Quagmire from family guy, then you would say "Giggidy!"

GTX/Ultra can use 2 bridges, but they are different, and it's not a bridge bottleneck.

No you'd still be stuck when you put 2 together, so while potentially faster than on a 16x(1.x) mobo, it wouldn't have any advantage over a 4 slot mobo for speed as each VPU still needs to make a 4 tap stop and then share communal chipset resources.

Not really, any slowdowns now are more driver related than hardware, which is similar to SLi.

Depends on the settings, as already seen the HD3870 does much better in Xfire than when comparing single card to dual and can beat dual G92s in enough situations to make it interesting. The scaling runs out for both though, however some structural limitations may limit SLi sooner, and may remove one of it's biggest advantages in the hardware based AA once you move beyond the 2 card model.

Which leads me to believe that the main bravado 'e-p3n1s' fight will be for who can get quad or more working smoothly with the highest efficiency. This would be an area where getting supertiling to finally work as expected would offer a greater advantage than more restrictive traditionally workload sharing.
