800/1000Mhz
256-bit GDDR5
1120 Stream Processors
56 Texture Units
16 ROPs
175W/25W power consumption

It's a cut down 5850/5870 core. At $200-$250, it looks like too much of a step down from a 5850.. 20% less stream processors, 20% less texture units, 50% less ROPs, 10% faster core.

I think it's going to have to be under $200 for it to be a good choice.. 16 ROPs, really?
 
Wow so they cut down the TMU and ROPs much more than the earlier rumoured specs of 1280 SPs, 64 TMUs and 32 ROPs. Knew the old rumoured specs were too good to be true when I showed how it would cannibalize the 5850 in the previous 5830 topics. Now it really is something in between 5770 and 5850 although 24 ROPs would've been nice. Gotta see some benchmarks to justify pricing now.

It consuming more power than 5850 sucks.

being that is new.. id expect the price to drop below 200 by the end of the month.. its like that with anything new.. price high at the start to get people to buy early and drop the price after the first months over.. though i have a feeling we may see these more in high end pre-built systems then people actually buying them to put in their systems.. also it could be them off loading a lot of binned chips that werent good enough for 5850's but still better then the 5770's.. we all know AMD/ATI is known for doing this so its not something we werent expecting..


damnit nice fix before i could get to it xzyrus.. was going to change the 5830 part to rumored 5830 :p
 
It makes sense if they had to give it a voltage bump to get it that high. The lack of ROPs and TU is whats going to hurt this. If they come at $200 then its not horrible. An extra $40 over the 5770 for better performance. At $250 though the card is a joke. You'd be better off spending the extra $50 to get the 5850.
 
16ROPS. yeah that kind of neuters it more than the SP.

In the bright side it will be more powerful than 4890. Hopefully much cheaper than 5850. Perhaps $200-229? It would still be quite a bit of step up over 5770.
 
I'm interested in seeing how much of a benefit the 256 bit bus is since there were mentions that the 5770 was starved when it was first released. Just looking at Texture and Pixel fill rates, it looks more like a pimped 5770 than a gimped 5850 although from a binning perspective, gimped 5850 makes more sense.

Also since it's more power hungry, wonder how the cooling solution for it will be since it's supposed to be cheaper than 5850.

Shame about halving the ROPs...24 would have been a good middle ground IMO. Also surprised at the TDP.
 
Looks like overpriced crap if you ask me.
Why does the 5770 beat the 5830 in Engine Clock, Pixel Fillrate, Z/Stencil, and Memory Data Rate?

The power consumption hike from the 5850 is right in line with the GTX 285 -> 275, and that binning was much more of a power draw hike. Conversely, the 275 bins offered performance at least close to the parent 285s. 5830: cheaper PWM, cheaper parts, and neutered performance. Likely offers the least performance:watt ratio for the Evergreen family.

I'm glad I got the 5850 when I did.

dang i had my eyes on this for 16x10 gaming but may have to get a 5850 or 5870

I think this will be a wonderful card for 1680x1050. You'll be able to max out nigh any game and throw in some AA and AF that the 5770 would not be able to provide. Still, it'll be at least $60 more than the cheapest 5770 when it comes out. It desperately needs to be more aggressively priced.

Because 5770 is clocked 850 core and 5830 is at 800. 850x16ROP=13600Gpixels for 5770. 800x16ROP=12800Gpixels.

memory data rate means nothing. It's just representing clock speed. What matters is memory bandwidth. Since 5830 has 256bit with gddr5 it crushes 5770 badly.

Engine clock again nothing more than clock speeds of the SP. 5830 has more SP so it won't matter.

is that chart official because if it is then somebody forgot to even list the memory bandwidth for the 5770.
 
Maybe there's still hope that these are inaccurate/fake? Although specs wise it does make a lot more sense. My expectations were unrealistically high from the previously leaked specs. Guess we'll know in 2 days.
 
I don't think we should be disappointed yet. If it is under $200 and had performance between the 5770 and 5850 I don't see a problem.
 
It should dominate the 5770 based on these specs, i dont know why you are so dissapointed?

Double the memory width, 300+ sp's and no doubt extremely impressive overclocking with voltage control. If this is priced at $199 it sounds like 2 of these in cf would pack an awesome punch.

Many more pages of 5830 content including egg shaped coolers and benchies I think. I'm still browsing it as I post.

Boo it only compared to 5850, 260, and 275. It's missing 4890.. LOL SC2 is among the games tested and the results seem a weird.

Power consumption does not appear to be higher than 5850 but temps seem a bit hot. O/C looks nice but they complain about the temp/cooling solution.

I guess it's because the 48xx line was so good that I'd be looking at a ~$225 card for what's probably a 20-25% performance increase. Maybe the 4850 set the bar too high for value.

It should be at least 20% faster than a 5770 which is very close to a 4870.

Here are where the game testing starts:

Thank you for the link. I can't wait to see [H]'s review on this!

*stares at the [H] staff*
 
Looks to be good video card for $200.

Comparing the HD5830 specs vs the HD4890 specs:

GPU
1.79 TFLOPs vs 1.36 TFLOPs
1120 SP vs 800 SP
56 texture units vs 40 texture units
16 ROPs vs 16 ROPs
800 mhz vs 850 mhz core speed

Memory
128 GB/sec vs 124.8 GB/sec memory bandwidth
1000 mhz vs 975 mhz DDR5 memory speed
256 bit vs 256 bit memory interface
 
One thing this is better than the 5770, it has double precision floating point which would help in GPGPU applications.
 
It does not look to be bad at all, but specs wise it has the potential to be better than 4890 so there's room for disappointment depending on how big the gap between them is. Then again spec wise the 5770 is a 4890 with 128bit bus... although pricing wise it's a tad lower.

Gotta wait for other review sites making a more direct comparison to 4890.

I just noticed they had the fan on 56% when they put the card under load. I'm trying to compare it to 5770 and 5850 reviews but I can't find the reviewer's fan settings.

Would have to compare it to the 5770 fan settings since the HSF on that XFX looks to be based on the 5770 eggshells, which is vastly inferior to the unit on the 5850/5870.

This has to be more than a happy halfway point between the 5770 and 5850 to be competitive at its price point IMHO, since the 5850 is such a good value. Fortunately the benchmarks look promising against GT200.
 
the high prices are going to make me wait until nvidia forces them to drop prices... assuming they can.
 
I am not happy about the higher power usage. I was hoping for something that was cooler and used less power than the 5850. Hopefully when its released the reviews will paint a different picture. Otherwise I must decide between a 5770 and a 5850 :(
 
It may fill the gap well between the 5770 and 5850 for the price. It will do what is intend. I'll look that the 5970 if i want to be impressed.

HD4890 is vanishing, folks; instead, you're seeing HD5750 and 5770.

In fact, HD48xx (as a group) is pretty much Going Away (except for the big e-tailers, like the Egg); for brick and mortar, it's purely a shelf-space issue.

I haven't seen HD4890 retail since Christmas. (That's not just BB, but even MC.)
 
price drops, not going to to happen until Nvdia launches their mid range in early 2011 (maybe), so if ou going to buy prepare to pay msrp or slighty more for the next while :)
5830 seems to perform at GTX275 matching price/performance and adding DX11 and eyefinity - this to me seems like a win.
