Radeon HD 5870 Six with 6 display outputs, prices, performance

[Glow9]

Texture mapping unit.

Thanks guy.

[LiquidReactor]

Hmm...does 5870 utilize vrms by volterra as well? Is 1Ghz going to be like stock clock for these cards?

[3Deye]

TMUs = Texture Mapping Units, these are responsible for applying textures on polygons.

As their number increase, the speed of applying textures increases >> Performance Increases.

You mean centrifugal right, cause your wrong on both accounts, they both share a centrifugal blower design of radial type time for some experiments i think

Radial flow and centrifugal are two names for the same type of fan/compressor. The other type is an axial flow fan and that is the type that you probably have on your cpu heatsink/radiator, for example. And yes, the NV fans are radial also. But blocking the inlet isn't going to make the fan suck air in from the sides, it will just starve it of air. The only way those little red ports on the end of the card could act as intakes is if they are ducted to the intake side of the fan. It's simple mechanics.

[~CS~]

Well why are those intakes are there then ? those cant be exhausts , air haven't pass trough any hardware to be exhausted , if inlet is closed fan is not going to be starved for air ,vacuum will develop and thus sucking air from the intakes , take all of this with grain of salt i have no education in aerodynamics just applying some common sense here .

Wondering this too, cause if no volt tweak = no fun.

Pushing hot air out of the case is usually the name of the game. I would really really hope this is what they did cause it doesn't seem like it would make any sense otherwise. I mean you'd heat up the inside of the case and heat up the card even more by doing so.

As he said, it's simple physics. The inlets at the back has to be ducted to the center of fan to be able to act as inlets. If it's just hole out the back the fan will be pushing air out through them instead.

Just saw over at Rage3d a guy says that they might have 6+8 peg, but only require dual 6 pin. he says 6 + 8 is there if you want it, or if you want to overclock...

I guess we just have to wait and see.

[OBR]

It seems Classic HD5870 has 6+6 PSU, Six version has 8+6 ...

I can confirm Performance of HD5870 about +/- HD4870X2 ... in some cases higher.

Can you confirm +/- for GTX 295 too?

[marten_larsson]

Can you confirm +/- for GTX 295 too?

If he says +/- 4870X2 then it's ~GTX295 too. The 295 is slightly faster in most cases but not all...

Thats how the 2900XT was. Overdrive would only enable in CCC if you used 6+8

I can also confirm this. Im sure future drivers should improve performance as well.

Then I'm sold for 5870.

I told you guys, Oct. is just a bit late for the cards. Should be Sept., well, not at all places though.
A distro. here is already accepting orders(started couple a days ago IIRC), just waiting for the 23rd/24th greenlight.
Should be the same in your place too.

[mod hat]The 100% better than 4870 threads/posts keep getting deleted because this is a News section....you need media sources. If you are the source, back it up with data. If you're under NDA and posting "100% better than 4870," you should probably reread your NDA and keep reading it until expires. Just saying ##% better than Card X without a media source or data is being considered spam.[/mod hat]

some guys here know it

and nice shock for nVidia

Hmm...does 5870 utilize vrms by volterra as well?

The heatsink-shot that turned up sometime ago pretty much confirms atleast HD5970 has Volterra chippery. No other type of VRMs would fit under that thin strip-like TIM pad on the VRM area. I'd say it will be 5 phases for GPU. Those 5 are probably shared between GFX core and "uncore" MEMIO, like on HD4890.

I wonder how well this card overclocks with 8 + 6 pin PCIE connectors. If 5870 hits 1Ghz easy that will put it miles ahead of GTX 285 FTW/ZOMFG/BBQ SLI set up.

The amount of pins on the external power connector has zero relevance to OC'ing. The 8pin plug offers nothing over the 6pin plug. Two cards; one with 2×6pin, other with 6pin+8pin, draw and receive the same amount of current no matter the level of OC.
8pin PCIe plug is nothing but a means for keeping PCIe certification.

It will be interesting to see how the x2 scales considering how the 'dual core' works in the single 5870.

Err... What?
HD5870 has a single monolithical die, and nothing points to any "internal dualcore" construction, either.

This is really annoying
Am I the only person slightly flummoxed by the general lack of Preview Benchmarks of the new 5800 series GPU?
I really could not give 2 figs about multimonitor stuff as I only have a single 24" display.
I thought the 10th of September was the day ATi were going to titillate us with a few benchmarks and pics of the new cards and specifications.. oh and release prices too.
What a load of tosh!

I'm sorry but that's not how it works. Plug the intake of a turbo, does it start pulling air in from the outlet? No, it simply hits the choke point. It's the same for this type of fan - they operate on the same physical principle. They could be intakes if they are ducted to the inlet side of the fan, but just having two holes there would make them outlets.

There are lots of reasons they would put exhausts there. One of the major complaints about the last gen was the noise of the fan and the heat. Having a solid shroud on that side of the fan might create a dead spot. If they made openings there they may be able to gain some extra flow from the fan without spinning it any faster. And the VRM heatsink or heatpipe could easily be close enough for air to flow over it on the way out of those vents - though you can't really see anything like that from the leaked pics. It sounds, to me, like ATI changed the design to satisfy the heat/noise whiners only to piss off the "heat dump into my case" whiners, LOL.

Solus Corvus,
The thing is, VRMs are between fan and the mounting bracket (Well, slightly under the edge of the fan) and not between fan and the proverbial holes.

Obviously not. There are countless people that for some reason bother moaning about it, in this thread alone.

I dunno why you thought that.
For me it was obvious they're not going to run performance benchmarks. 10th was a known from the beginning not to be the launch event, but just a feature show / marketing act.

[Solus Corvus]

Solus Corvus,

I can see that. But I can also see that there doesn't appear to be any ducting from the holes to the intake side of the fan. Just because the VRMs are close to what they are powering doesn't mean that there isn't a heatpipe or heatsink fins/pins on the side that we can't see.

[Hornet331]

Wondere why everyone says performance is 2x4870 when everyone says it performs as good as a 4879x2. That means it performaes somewhere ~60-70% better.

The performance was somewhat expect, due the fact, that the 4870 also was in the range of a 3870X2.

Looking forward to it, also i hopethis round there will be cards with waterblocks around.

[flopper]

somtimes its hard to understand people, ati has sown maybe the best ever gamechanging experience, ever.
and people moan about performance numbers?

running 6 screns with WoW at 80fps, is enough to show, there is some power there.
FPS is what counts, togheter with some eyecandy and obviously even more important, how it feels like gaming that resolution.

holy s-h-i-t batman!
that is the reponse people have had to the tech.

You're wrong, it is a single die but its structure is the same as a "dual core" cpu.
