Info leaked on 4830

Twice the stream processors as my 3850 in the $100-$125 range is pretty hot. Considering I still game at 1280x1024 this could hold me over until dx11/new monitor.
 
Wow, I still have a 3850 as well, but mine is only a 256mb. I game at 1280x1024 also so this card may be killer for me too. Looking forward to some benchmarks against the 3850 256mb.
 
I have been watching this card also. The real question for me is how does this card perform against the HD4850. I also have a 256 mb 3850 and am looking for something with a bit more muscle.
 
I'd like to see how this compares to an 8800GT. If it performs significantly better, for $100 I just may have to jump on the upgrade.
 
I'd get one if it's passive and has dual DVI-I... I 'd think it would be around $110, they have lower-end 4x00 series cards to sell as well.
 
Mmmm... I would take this fud with a HUGE grain of salt (like larger grain of salt than from 99% of the crap that comes out of his site). Where would this card fit in?

Enthusiest = 4870x2
High End = 4870
Mid-High = 4850
Mid = 4680
Entry Level = 4650
Non Gamer = 4350

I doubt they would replace the 4680 with how well its doing.
 
ya was about to say the 46** are to be the low end below the 4850 around the $50-$00 price point with dual HDMI and other crap in it.

ATI doesn't have anything to compete with the 9800gt. The 4670 is too slow and the 4850 is too expensive. Around the $110-120 price range the 4830 would be a good fit.
 
if it comes in at 110-120 it's bought. I need a new graphics card and that would fit my budget perfectly.
 
Enthusiast = 4870x2
Less-Enthusiast = 4850x2
High End = 4870
Mid-High = 4850
Mid = 4830
Mid-Low = 4670
Low = 4650
Even Lower = 4550 = 4350 with dual-stream UVD2 (hardware PIP) + DVD upscaling
Lowest = 4350

At least the numbers follow each others...

Check the VGA charts over at Tom's. The 4850 is better but its not really stomping the 8800GT (aka 9800GT now). Unless ATI wants to cannibalize their 4850 sales, they 4830 would have to perform just about the same as a 8800GT so I doubt it would be an upgrade:

Looks like ATI is putting out this card just to compete with the 8800GT and 9800GT cards, performance will be about the same.
 
I'm sure the 4830 are chips that just didn't make the clock of 4850's and 4870's. I'm betting it'll be a short-lived card.

More likely to have defective stream processors- otherwise every defective 4870/4850 just gets tossed in the trash.

I'm interested in how it performs, although I'm not in the target audience. I just stepped down from a 4850 to a 4670 for the power savings.
 
Three models now available from newegg all for $129.99 + $8.25 Shipping.

I'll wait for the price to drop.

Stream Processors: 640 Stream Processing Units

I'd have to wait to see some comparisons between it, the 3850 I have, and the 4850, or 4670 to see how it compares.

guru3d has a 4830 in their FC2 benchmarks. It's about as fast as a 8800gt.

Thanks, I hadn't found those scores.

Based on what I see there, and prices or the three cards I am looking at to replace my 3850...
- The 4670 even for $80 isn't enough of an upgrade
- The 4830 is a decent performance upgrade but not at $129 when I can get a 4850 for $129 after rebate.

Either the 4830 needs to come down to ~$100 or it is not a good upgrade.
 
4830 at the 'egg for 129 with 10 dollar MIR. Problem is that they have approx 8 dollar shipping killing the deal.

Need to see some benchies to know whether or not this is worth the little price difference over the 9800 GT or if it is too close in price to the 4850!

I'm not seeing this as being a good spot, definitely needs to hit the 110 shipped mark or blow away the 9800GT in benchies, but even then it's priced too close to the 4850.

Chart from AMD comparing the 4830 to a 9800GT:

AMD seems to be very optimistic.

Nice, looks like they had Apple teach them how to make misleading bar graphs.

$129 is definitely too close to the 4850 prices. This will likely to a little over $100 fairly soon.

AMD sent HD 4830 samples to reviewers with missing shaders

... When I added shader count reading support to GPU-Z yesterday, I noticed some contradicting numbers. I have two HD 4830 samples here: one card from AMD, and one card from PowerColor. Both cards are reference spec HD 4830s, both are supposed to have a shader count of 640 - just like all other HD 4830 cards.

The GPU-Z readings however showed that the AMD card had 560 shaders and the PowerColor card had 640. How is that possible? If 80 shading units were missing, then this could mean a performance hit of up to 10%.

--

so that means some of the reviews may be wrong, depending on what card was sent to them for review

Someone must have really screwed up in the factory for that to happen.
 
Here's another review:
http://techreport.com/articles.x/15752/1
Looks like ATI made sure that this thing was a bit ahead of the 9800gt in terms of performance.
Seems to get a few frames higher in most cases at the same settings and resolution.
The only downside I can see is it runs a little hotter.
 
If you don't take rebates and special offers into account, this card is priced right and the performance is good for the price. Whether this card, the 9800GT, 4850 or 9800GTX is the best choice in the price range will have to depend on the current situation as far as rebates.
