The ATI Radeon HD 4830 graphics card is the latest addition to the award winning ATI Radeon HD 4800 series lineup and comes packed with the power and premium features you need to take gaming to the extreme. Read on to see what AMD did to cut down on price and how it will impact the performance of the graphics card.
AMD has done a great job bringing the Radeon HD 4000 series to market and they now offer a product at every price point available and the offerings are impressive. The AMD Radeon HD 4830 was found to be a solid performing graphics card that was able to play current game titles at decent resolutions with many image quality settings cranked up. How can you complain with the performance numbers on the Radeon HD 4830 when the price point is only $129?
Wow ATI is really putting the hurt on Nvidia finally. This I hope will get Nvidia back to where it belongs, in the lab working on some uber chip that will be a quantum leap forward.

I'm re-benchmarking all the cards on core i7 right now, so I didn't want to spend too much time on this platform.
The charts as they are include 15 different video card setups, which is a ton of testing as it stands. For this article I added three new cards to the charts
Radeon HD 4870 1GB
Radeon HD 4850 512MB
Radeon HD 4830 512MB
I was going to do just the Radeon HD 4830, but it needed to be shown against the other Radeon HD 4800 series cards. So many new things are coming out soon it's insane. I haven't seen it this slammed in the 6 years I've done the site. My apologies for not including more cards, but the stuff coming down the pipe is better if you ask me.
HD4850 with some of the stream processors disabled. Not too shabby, might want to check the vGPU to see if they are undervolting it to reduce power consumption. I imagine those cards could easily go to 800-900MHz with a flick of the soldering iron

So I was going to make a thread on this....but decided not to. The following information was taken from HWC forums.
Some of you may know (but only a few of you may actually care) that today marks the release of ATI's HD 4830 which is supposed to compete directly with the 9800 GT errrr.... 8800 GT 512MB.
Unfortuantely, the folks over at Techpowerup have learned that there seems to have been a serious problem with the review samples ATI sent out to numerous review sites. Basically, it seems that somewhere wires were crossed and cards have been shipping with 560 Shaders versus the specified 640.
The odd thing is that some cards have the nominal 640 shaders while others are gimped. This results in an approximate 10% performance difference between the two cards and unfortunately puts some serious questions behind all of the HD 4830 reviews that have been posted. Were the reviewers using the "proper" card with 640 shaders or the one with the incorrect shader count? In this Hardware Canucks stands behind Techpowerup in asking that all review sites publish which card they used for their benchmarks.
Even more unfortunately, this casts some serious doubt upon the cards currently making their way to the retail channels. The consumer has NO WAY of knowing if or how many 560 shader equipped cards made it to ATI's board partners. This means that any number of HD 4830s could be underperforming without the customer realizing it.
Will this mean a recall of the cards? If not, will ATI release a statement? One way or another, this little slip-up puts some serious doubt upon the launch of this card. Hopefully, the launch will be trouble free after this speedbump but until things are put to bed with this situation...buyer beware.
Unfortunately, UPS still has posession of our card so we can't verify this for ourselves. Long story folks, don't ask...
You can find all of W1zzard's investigation HERE and I encourage all of you to read through it. That is what good journalism is all about folks!!

According to the new GPU-Z beta that Wizzard made the one I have also has just 560 stream processors and not 640... Wonder what the deal is on that.
I downloaded GPUZ 0.2.8 last night and it showed this, which is why I didn't post it in the article.

With they had the update last night.
I just called ATI and they are looking at the utility to see if it is reading correctly and they are also looking at the cards BIOS versions to see if that has something to do with it. Seems there might have been a last minute ASIC change that could be at play here as well.
Correct me if I'm wrong but I believe GPU-Z actually looks up through a database within the executable itself to find the number of stream processors for the given processor. I remember when the HD4850 came out for a little while it said something like 640SP instead of the 800SP that the GPU really has.

i like the way you think
I think you guys are dangerous....

Just a little puppy trying to make it in a big digital world.
With ease. The core power regulation looks exactly like the HD3850/HD4850 meaning up to ~1.75v is possible. If it's just a neutered RV770 then I imagine ~800MHz is possible on the stock cooler and ~900MHz possible on aftermarket air so long as the cores themselves aren't terrible.

I agree!
I'm looking for a gfx card for my sister for christmas. I'm stuck between this and the 9600 GT. Looks like the 9600 gives the 4830 a run for it's money. The 9600 is cheaper than the 4830, right? Any recommendations for a card at or below $100 USD?
It seems that this card had a BIOS on it that disabled one of the SIMDs in the core, which means that is was only running on 7 SIMDs. By doing a BIOS flash the other SIMD is enabled and all 640 stream processors can be used for rendering and so forth.
Here is a statement from AMD:
"AMD has identified that a very limited number of ATI Radeon™ HD 4830 boards have shipped with an incorrect BIOS which may impact performance. This is in no way hardware related, and an updated BIOS fully resolves the performance limitation. AMD has provided its board partners with the updated BIOS. Please contact your board manufacturer for instructions on updating the card BIOS."
It also seems that most cards on the market have the right BIOS and that mostly just review sites are impacted. With so many reviews in the works, we won't be going back and updating all the numbers on this one. If you have a card and need to update the bios you can grab the BIOS here - http://www.techpowerup.com/vgabios/2561 ... 81023.html
You might wanna add that part into the review Apop, just so other readers can know what's going on and why there's such a "big" performance difference with your results compared to other sites.

hmmm, I wonder how much this affects the performance. I was leaning towards the 9600GT. Do you know when you might have the numbers update by?
