Hm, interesting. Confirms suspicions that it's a slightly detuned 5850, in essence. 2/18 seems rather optimistic, though.I think the latest rumour was Feb 18 and there were leaked specs somewhere.
Edit:
http://www.techspot.com/news/37894-unannounced-radeon-hd-5830-price-and-specs-revealed.html
I think it's silly that the MSRP for the 5850 used to be $259, but now pretty much everyone, including AMD, has accepted the new price point of $299. So, when the 5830 is announced it'll probably be $230-250.I'd much rather have a price drop on the 5850 than a 5830. I'd wager the 5850 will drop down to this supposed 5830 price point when the GTX 470/480 releases.
Maybe trying to steal some Fermi thunder with a nice value card?Word goes that they're plentiful but AMD's asked retailers to keep the lid on for some reason. Might be they know something about that upcoming major price drop that will coincide with Fermi.
I'm wondering if the 5830 will be a suped up Juniper, or a cut down Cypress. If it's the second, AMD might be putting themselves in a hard spot, as if they create a huge market for it they'll end up having to use good chips that could be a 5850 or 5870 and loose out on profit(Look at the Phenom II X2 and X3 and how many of those are actually fully functional quads). Maybe it'll just be a P.E.(press edition or phantom edition) just to steal some thunder away from Nvidia. Unlikely, but plausible. Either way, we should have the killer 5000 series mid-range card.
At this point, it's been 4 months since release, they probably have enough chips coming off the wafers to support 3 different Cypress binned lines. It might help them make use of chips that can't make the 5850 cut as they can't be dropped into 5770s.
You would figure at this point in the chip's lifetime that yields have gotten better, and there won't be many card coming out that can't at least be used for 5850s. I'm sure there's some, but if they sell well the initial reserves will be used up and they'll have to harvest good chips. Depending on what the price is, and how much the chips cost to produce, this could be not so good since AMD needs as much profit as they can get to start offsetting their huge debt. The Intel settlement only went so far, and it wasn't nearly enough.
Someone on another forum said an overclock of core speed to 843mhz will match 5830 with 5850. And that considering 750mhz is the standard, it should be plausible.
Looks like it might be a cannabilizer. If it cost $50-75 less than a 5850 and can be reliably overclocked to actually meet it's performance, then we might be looking at the AMD version of Nvidia's Ti4200. It's going to be an interesting time to be a PC hardware consumer with the two giants looking to duke it out.
They are supposed to be as fast if not faster then a 4890.
So the 5830 is a 4890 with DX11 and all the other new features.
I thought the rumored core speed was 750MHz?http://en.wikipedia.org/wiki/Comparison_of_AMD_graphics_processing_units
With the rumoured specs on wiki 816mhz core on 5830 beats 5850 already. Since they both have 32 ROPs and the 5830 already has a higher clock, the 5830 already has a higher pixel fill rate at stock.
72 x 725 = 52,200 texture fill rate of 5850
52,200 / 64 (TMUs of 5830) = 815.625mhz
That's the core required to be even with the texture fill rate of the 5850. At that core the pixel fill rate beats the 5850 by even more. So if a 10% overclock is possible (which it usually is from my brief knowledge - correct me if I'm wrong, only been following computer stuff since Aug 2009), the 5830 will beat a stock 5850 on texture fill rate as well, but before I get carried away, it still does have fewer SPs so I'm not sure how that affects it.
What worries me however, is that when it missed the rumoured Jan26 and Feb 5th release schedules, there were rumours saying it was PCB issues.

I'm hoping ATI is holding it back simply to avoid cannabalizing its 5850 sales.
Edit: The stock core is weird to me since all previous releases of lower graphics cards in the 5#xx always has a lower core than the higher 5#xx. Rumours could be wrong I guess.
I thought the rumored core speed was 750MHz?
The 725mhz I used is the 5850's core just to show you the texture fill rate of 5850 which I went on using to derive a core speed for 5830 to get the equivalent texture fill rate of the 5830.
If they gimp the 5830 to 128 bit then it might make sense at 750 mhz but as of right now, it looks like a real cannibalizer. If it's 256 bit then something like 650 mhz makes more sense.
they must be gimping it else the model wouldn't make any sense unless they called it 5860.
The still-unannounced 5830 reportedly packs the same Cypress LE core used in Radeon HD 5850 cards, but with 1280 stream processors instead of 1440, and will be able to crank out 60 texels per clock rather than 72 on the 5850.
The memory configuration will remain the same, 1GB of GDDR5 memory operating at 1000MHz, but apparently the core clock has been upped from 725MHz on the 5850 to 750MHz. Physically the two cards will be very similar, possibly using the same PCB and cooler...
No, you (and I, and many others) misread what he posted. He's saying that with the rumored specs (shaders, processors, etc.), all you need to do is bump the core to 816MHz to beat a 5850. Considering it's allegedly at 750 already, it's a measly 66MHz bump to beat the next-highest card.He's not doing it right. What he's not taking into account is that the 5830 is suppose to have 1280 SPs while the 5850 has 1440 SPs so the 5830 should be roughly 10% slower all around.
But, I don't see why they would up the clock speed as much as they have, 725 or 700 just makes more sense for it.
Wait. Why/how did he pull 816mhz core out of his ass? Everything has been stating that the core for the 5830 is going to be 750mhz.
