Some more info on the 5830..

I am still trying to figure out the Eyefinity 6 model.

Having the 6 video outputs is nice, but what happens to the 2 GB VRAM if a person tries to run another HD5870/HD5970 in Crossfire?

Maybe the regular HD5870/HD5970s will be coming out with 2 GB models?

What do the posters mean by dp timing?

 

[RaistlinZ]

I think we'll still be looking at a base price of $250 for this card, what the MSRP on the 5850 used to be. I hope the performance is significantly better than a 5770 though.

I think what it means is the video card will handle display port timing so you can get a passive display port adapter instead of having to buy an active one like with the current cards.

I would rather have the 5850... more shaders & more OC headroom. Hopefully they have a nice PCB on the 5830

Those specs are fake.
Why would it pull more power then a 5850?
It also has 1280 sp's.

it's higher clocked, that takes a lot lot lot more power-- higher voltage and more transistor switches or flips/second (75/725 aka 10% more switching being done).

It says something truly awful about the state of my subconscious that I dreamt about the ATi HD 5830 a few nights ago. Granted, it was only a bit part (I was checking off parts on a machine that I needed to... save the world... or something), but why dream about the 5830 of all things? I'm still not sure where this card will fit, in the real world, especially if the 5850 price becomes more reasonable.

Hehe, where'd you get that info?

I just wanted to add that it sucks more than i originally thought... it has the pixel fillrate of a 4870, 16 rops, slow zstencil, and comes clocked rather high out of the box. Not to mention the 1120 shaders.

 

[bryanW1995]

yeah, but maybe they'll be able to price a regular 5830 under $200 at least...

those specs just seem odd compared to the 5850 and 5870. why would thy cut the ROP number in half? why would they reduce the SP count by 320 but then clock it higher?

I doubt that chart is real because if it is then somebody forgot to even list the memory bandwidth for the 5770.

Dude...

LMAO at your obviously out-of-control computer hardware obsession. Not that I can't totally relate though...

 

[GodisanAtheist]

I really appreciate AT's color scheme.

That being said, the 5830 couldn't come out soon enough.

 

[blanketyblank]

It's really just ATI competing with themselves at this price range though. I doubt Fermi will be released anywhere close to these cards though maybe the 470 can pressure the 5850 if it's really 300 and there is sufficient availability.

Cutting ROPs means that they can limit performance more, maybe? (Keep it above the 5770 but below the 5850 with no chance of overclocking/etc to come close).

As for the SP/clock thing, well, I would assume it depends on yield. If the main issues with the die are defects, and not clocks, then it seems reasonable that they would be able to harvest a lot fo dies with 320SPs disabled, but potentially run them at high clocks.
If the issue was few defects, but the speeds were poor, then it might be a different story.
If these specs are true, it might just be an indicator of the type of problems affecting yields (although the increase TDP also implies, as has been suggested, increased voltage).

Of course, that assumes these specs are accurate and this is what we will be getting.

That's what I don't understand, or at least I don't agree with my assumption. I mean, it seems purely a move to cripple the chip to fit the price bracket, unless AMD is really having trouble with ROPs on the chips. I mean, these are basically damaged Cypress cores that AMD is trying to offload. Still, it doesn't make sense to pair that kind of memory bandwidth and then starve the chip by lacking ROPs. Still, these cards could be killer in a Crossfire setup if they're priced at $200.

 

[Tempered81]

Maybe these chips had spotty defects in the raster outputs and the alu/texture mapping units, so by setting the bin limit to 16 rops (32 - 16) & 1120 sps (1600-480), they are able to produce more chips for the "5830" product specifications. They can harvest up to 4 sections of rops, and 6 complete SIMD blocks. To get to the 800mhz target (speeds needed to keep performance up over 4800 & 5700 line-up), they just have to put in whatever required voltage and push the mhz up into a relatively save range. (800mhz). That voltage is also what is increasing the "max board power". I bet we see these cards ship with a higher stock vgpu than the 5850. This also decreases overclockability, and keeps the product from interfering with 5850/5870 sales, while at the same time not enticing all the buyers from the 5770 product. Yet it does provide a product in the 5000 series price gap between $180 & $290

This way they get much greater supply for this product than if they opted for 32 rop / 1280sp. And with those specs, then it gives the card the potential to reach the 5850 & 5870, because the clocks would have to be in the 500-700mhz range - which would be a cake walk for a cypress die, and give it huge headroom for the enthusiast.

I'm thinkin' if you're on the fence over 5770/4890/5830 and are spending ~$220, you may as well go for a cheap or used 5850 in the ~$275 range. You will get s000oooo much more product value, performance, and potential performance.

 

[GodisanAtheist]

@Tempered: That's exactly what I was thinking. If the whole point of the 5830 series is to harvest busted cypress dies, it would make sense to make the specs as inclusive as possible while hitting the target performance. Reducing the SP's to 1120 & ROPS to 16 might bring large volumes of otherwise throwaway cores into the mix.

As the 5830 is supposed to just use the 5850 PCB, it would probably be very easy for ATI to scale the power requirements to hit the target clock speeds, with the added bonus of ensuring 5830's don't start cannibalizing lucrative 5850 sales (thanks to OCing).

If the target is 4890 performance, an 1120SP/52tmu/16ROP core @ 800mhz would do the trick.

Is the 1280SP thing confirmed confirmed or is it LOLconfirmed like so much VC news is nowadays?

Higher voltages,less overclocking,higher speeds,only 1120 sp's now= crap.
I wanted this card to crossfire.:\
