Until GX200 comes out!

@55nm...

Nice quote
It comes out in August? Come on, step it up AMD If they release it on 25th they would definately be on top

why is it dies are shrinking on CPUs and requiring less volts and less heat but GPUs are hot as heck (78c idle 4850)


kinda sad when a quad uses 200w and the GPU uses 600 watts LOL

Mind showing me a GPU that uses 600w?
4850 is idling hot since the fan is only at 10% speed on a single slot cooling solution and powerplay doesn't seem to be in full effect.

The stock goop on the early 4850s is pretty bad. Replacing it will give at least a 10c difference.

Do you think that would still be the case if ATI offered their R700 as a true dual-GPU solution?

my thoughts as well.
there has been no evidence to support that it will stutter, and plenty of releases albeit unconfirmed saying it won't due to the design change. As it will render like a single gpu...

all i know till now is that CFX with 2 R700 showed 4 gpus, so i dont think we'll see that one 4870x2 will be handled as a singel gpu.

Well perhaps I am being a bit too harsh but basically in my uneducated opinion Crossfire and SLi are both flawed.

These technologies do not support every game out there and require you to pray to the driver gods for a driver which is good for SLi or a Catalyst that supports Crossfire in X-Game or Y-Game....even in some cases a game has to be PATCHED to support SLi/Crossfire.

And then.....we have the issues of st.st..st..stutter this is caused by frame buffer synching (or lack of) which can in some cases give lower minimum frame rates as the CPU is having to do extra work!

Rumours suggest that HD4800 series have somewhat sorted out the way Crossfire works (and yes the scaling is phenomenal) however you still have the same old "this game doesnt work with Crossfire issues"

IF it is true that the HD4870X2 is not Crossfire based and is true multiGPU then wow

John

it's simple for me; whatever gives me maximum fps with 8xQ AA in Empire: Total War is what i'm buying.
4870x2 or gtx 55nm if any driver probs, then no sale...and it's a long wait until my game is released :}

micro stuttering fixed

Seems the new method of communicating between cores through memory, is supposed to keep the frames fed to the monitor at a proper rate.

[gojirasan]

Those are just rumours, villa1n. They are utterly unverified. And part of the information has already been shown to be false which seems to place some doubt on the rest. I certainly hope it is true. It would be revolutionary. but it seems almost too good to be true. I'm keeping my fingers crossed though.

as gojirasan said, its oldnews (or more like old rumor ).


I believe it when i see it.

[[XC] gomeler]

No it would not, then you would put all that warmth that is being emitted close together and you need to spread this heat anyway to dissipate it fast. It wont gain you anything for air, water, DICE nor LN2 cooling, now you can put 2 separate cooling blocks on each core.

Uhhh.. I have no problem cooling my QX9650 at 5.5+GHz, I think I could handle some MCM'd RV770 cores. This way I'd only have to insulate around one die, only have to deal with 1 evap/pot, and in general simplify cooling the gpu. It'd be like another R600

Though I share in your suspicion when dealing with rumous about new advancements prior to actual launch, you do have to accept that at some point micro-stuttering will be completely gone, for both ATi and Nvidia. It's a big enough problem and I'm sure both are working on it.

I would not be surprised if we hear the last of micro-stuttering before the end of 2008.

4870 X2 is not like two 4870s
4870 X2 is a virtually single-chip videocard => any game not supporing crossfire will run great on 4870 X2

lol wrong. It's two chips, and identical to the 3870x2 but with 2 rv770's

[Unbornchild]

It's not identical. It's a substantially improved architechture.

[cegras]

Oh, you mean like the 480 SP's?

[LordEC911]

Awww... you got to it first...

[oohms]

I thought they were just going to use a better bridge chip? Didn't the one in the 3870X2 only support pci-e 1.0?

[Chickenfeed]

Theres still no conclusive evidence as to how the R770 cores will communicate to each other. I am sure however that AMD has managed to considerably improve how the cards communicate to each via either a faster PLX/PCI 2.0 bridge or a custom interconnect. I'd be pleasantly surprised if the cards do function as more than mere crossfire but I think this is somewhat unrealistic at this point in time. I have no doubts however that this card will be the fastest single pcb solution in supported games. If they scale efficiently across a large number of titles it will be a killer card. I just hope the memory limitations don't bite ATI in the butt down the road. I still feel that the GT200 architecture has more longevity to it ( Nvidia's design is more forward thinking but ATIs seems to prosper in current titles ). Time will tell.

[MAS]

the thoughts are the next:
AMD claimed it's top videocards will be all multi-gpu. But todays 3780 X2 and 9800GX2 have troubles in games => they cannot be recommended as universal card for gamer.
So I suppose AMD has already solved microsluttering problems for its top HD4000, 5000, etc series, otherwise there's no sense to sell 4870X2 since everyone can buy GTX280 and forget of any trouble

[Chickenfeed]

Indeed. For AMDs new approach of using multiple inexpensive dies to work, they will have to of remedied many of the short comings with current multi gpu configs, such as micro stuttering and inconsistent scaling/compatibility problems. They claim that after Nvidia sees their new approach on the 4870x2, that they will be making their concurrent offerings in a similar fashion. I do agree that this method is best for us as consumers ( as Nvidia's method of disabling hardware capabilities is somewhat lame ) and it should result in more affordable, yet still high performance, gpus. This would suggest to me that they have indeed designed a vastly improved bridge and hopefully this is the case. I would love to see unanimous scaling in games with these cards.

I'm still holding my breathe on this though but its what we should want to happen for the sake of progress and competition. For this all to go mainstream they will have to do more than plain old crossfire as its the only way this will be universally adopted and their high level of confidence sure seems to suggest this. Hopefully its not just PR hype. The current inconsistency of multi gpu sucks to put it bluntly so anything that improves this is welcomed. Sure multigpu usually will offer improved performance but its often quite small given the substantial increase in cost. What we need is a highly efficient method of scaling multiple cores and SLI/Crossfire isn't it. I won't touch a 4870x2 if its merely plain jane crossfire. For consistency's sake I'd more likely get a single GTX280 and be done with it. Hopefully AMD will prove us all wrong.

[Sr7]

Oh, you mean like the 480 SP's?

That's funny, coming from someone who doesn't have a clue. It was well known that they either had 480 sp's with a separate shader clock domain or 800 SPs. 800 was extremely unlikely (actually a bad design choice, but good for marketing terascale) and amazon showed the specs at 480 SPs, so I had a perfectly good reason to think that's what it was. By the way, performance in shader heavy games is not 2.5x... so something smells fishy there.

That and maybe I've seen an R700

By the way, don't hesitate to keep your smart ass comments to yourself.

[saaya]

the 3870x2 isnt much slower compared to the 9800gx2, which is about as fast as the gtx280... so it seems very likely the 4870x2 will beat the gtx280 or at least offer the same perf... and it should be cheaper.

so while ati still wont win the performance crown as nvidia can do tripple gtx 280 sli which is like hecta 9800gx2 sli, but you can all see how the prices are falling down, thanks to ati beeing back on track after their r600 set-back

If Nvidia doesn't get Nehalem license their SLI is basically obsolete. So why spend load of money on triple whatever from Nvidia.

Ya, because everyone *needs* a Nehalem based system

Same here.
