ATI Radeon HD5830

that looks like a nice card but why is the power consumption so high at 175, do they have to power the cut sections that much

[overclocking101]

Yeah thats odd. are there any actual leaked photos yet??

[cegras]

That's not power consumption, that's maximum board power. I'm guessing that's how much power that one is allowed to feed through the board, and it may be higher than the 5850 due to VRM inefficiency, etc.

16 rops? sounds more like a HD5790 than a HD5830 IMO

Also, if you buy an HD58xx series you're an enthusiast. But why be that when you can be an Ultra Enthusiast by buying an HD59xx series!

[WARDOZER9]

I Agree on the ROP count, should be 24 or such. Then again it's aimed to be the bastard child of the 5xxx series so 16 should help it meet that goal. So far I'm not liking what I see. I'm pretty damned sure the HD 4830 didn't launch at $200.

In comparison the 5830 is aiming to be more seriously neutered compared to the 5850 than the 4830 was to the 4850.

[Manicdan]

feels like the 5830 is just whatever left over broken 5870s that are about to make a one way trip to the dumpster. i cant even tell if a 5770 is going to be faster

[zanzabar]

the 5770 with still slower than the 4890 (right below the 4870 normally) and at the same price point with this at the same price point as the 4890 and 5770 was it should be a nice card for the price especially once the ferni is out and it drops in price a little

[bhavv]

Its looking more like a 5790 to me too, but the 256 bit memory would put it into the 5800 category as thats the main difference, though a 5770 with 1120 shaders for less cost would have been awesome.

I dont reckon the extra performance from two of these would be worth the cost or power consumpsion over a pair of 5770s @ 1 Ghz, but individually they fit the gap between 5770 and 5850 nicely.

I'd still rather pick 5850s instead for 'enthusiast', or 5770s for 'price to performance'.

The problem with the 5800 range this time around is the vastly reduced number of shaders, whereas 4800s just differed with clock speeds I think.

Ive been converted to crossfiring the *770 cards from now on anyway, I'm waiting for the 6770 later this year .

Also, according to Ati, Im no longer an enthusiast, but rather a performance something ... A perthusiast, or enthusimence maybe???

I hate confusing charts.

[jaredpace]

Wow take it ez with the laser ati. I thought this thing would have more shaders, that makes the 5850 the value leader for cypress



edit: damn, and they cut the rops in half? WEAK. This thing sux, for 5800 series, but i bet it still sells...

[zanzabar]

they are taking otherwise dead gpus and using them, it seams like more of a tsmc problem that they have to do this instead of underclocking parts for the lower cards

[CrimInalA]

I have been waiting for this card , but it looks disappointing .

24 rops and 1200 stream processors would have made me buy this card . Now I will just aim for 5770

It is better than a HD5770, so if you were waiting for a card between that one and the HD5850 you should consider getting it.

[Manicdan]

over time due to the extra power consumption, i bet can end up costing more than a 5850. that would be sad

[LightSpeed]

Well, lets see how much the reduced ROP's affect performance before jumping to conclusions i guess

While disappointing, pricing will ultimately determine its value

[WARDOZER9]

Are there any good GPU's for comparing ROP count and related performance? Honestly I would like to know the eirect impact on ROPs with recent games. Can someone do a bios mod on a 4xxx or 5xxx series to shut down some ROP's without touching shaders and give us all a good comparison to see if the neutered ROP count on the 5830 or any card makes much of a difference?

It would seem on paper that the 5830 would be closer to the 5770 in perfomance than the 5850 but I'm hoping ATI thought this one thru and I'm wrong.

I think the 175w thing is a big ol typo, maybe they mean 125?

[LordEC911]

I have a feeling this is the perfect card for the 1680x1050 crowd.
Once you up the res to 1920x1200/1080 the 5850 should pull ahead due to the ROPs but the extra shading power at 1680x1050 should keep it ahead of the 5770.

Edit- I too was hoping the ROPs wouldn't be cut this drastic but it makes sense to make sure it stays under 5850.
The overclocking ability of this card is fantastic though that is due to the fact that the cards from AMD are on a highend PCB, as some have already pointed out.

Wow, that's retail cards with 5870's PCB. That's fantastic!

As SKYMTL said in this post, there's no reference PCB by ATI and all cards sent ro reviewers have 5870 PCB and clock like a bat from hell:



If this is a trend, 2 of these 5870 PCB'ed 5830 in CF for around $400 will be really sweet, 16 rops or not.

[zanzabar]

if thats the toxic pcb like the cooler looks then i doubt that it will oc without a hard mod as the voltage is normally non variable on non reference cards that arnt advertised with it

[Lokinhow]

well, I think the 16 rops makes sense.
probably ATI don't want people buying HD5830s and getting HD5850's performance overclocking it a bit.

It needs to sit between HD5770 and HD5850, something like GTX275/HD4890 performance, with this specs it will do the job.

So how does that fit in with unlocking 550s into X4s. Maybe we'll see a similar sotfmod...

[eric66]

specs are dissapointing hoped for more rops damn you ati

[Astennu]

I think the TDP is rated for the Whole chip to be loaded at 100%. And they did not take in to account what huge parts of the chip are disabled.

Look at the stats:
VS HD5850: 75 MHz higher clock 20 Watt more
VS HD5870: 50 MHz Lower clock 13 Watt less

It would not surprise me if the reviews show that the HD5830 consumes less in furmark and games compared to the HD5850.

And the ROBS who say's they can keep 24 active ? Maybe they only have 2 clusters of 16 ?

[dartaz]

HD5830:

- Higher power consumption than HD5850
- Only 16 ROPs, and has lower pixel fillrate than HD5770 at stock speeds


I don't think it will be much faster than HD5770, and at the same time it will consume more power than even HD5850. Thats really dissapointing
