Update: AMD has confirmed to us that there were some issues with the BIOS on our sample board. Rather than 2 disabled SIMD units, our review sample 4830 had 3 disabled SIMD units. AMD has assured us that no retail boards will be affected and this is only a problem that affected reference boards built as review samples. We are working on resolving the issue with our review sample and will complete updated tests as soon as we can. This will affect our performance results, but until we run the tests we can't be sure how much more performance we will get out of retail 4830 hardware.

Update 2: We have updated all the performance graphs in the article with data re-run on a card that actually has all the SIMD's available. There was a difference, but it hasn't changed the overall conclusion of the article. For more information, see our update article with details on the problem, the situation, and performance differences.

Since the launch of the RV7xx GPU, AMD has been steadily filling out a top to bottom Radeon HD 4000 series lineup. The first markets addressed were gamer centric with the 4850 and 4870. Next in line was the hardcore enthusiast class with the dual-GPU 4870 X2. Since then we've seen the 4670, the 4550 and the 4350 filling out the bottom end value and mainstream segments. But there was a bit of a performance and price gap between the 4670 and the 4850. This gap has now been filled.

Today we see the introduction of the Radeon HD 4830 which is to be priced at or below $130. This part is poised to split the difference between the 4670 and 4850, and filling in this market segment should finish rounding out AMD's line up of RV7xx based cards for now. At least we hope.

In the past both ATI and NVIDIA have flooded the market with way too many different models that overlap in price and performance in ways that just confuse their customers. While AMD has been releasing cards at a fairly steady pace, all these parts have been well positioned and have served to disseminate their new architecture. We have been really happy to see how quickly AMD has gotten their new GPU out into the world.

By now, we've covered the architecture and other versions of the hardware quite a bit. The really interesting bit about this launch is the price and the prices of competitive hardware.

    While the text says 1 simd disabled (which is clearly wrong), it seems AMD sent out review samples with 3 simds disabled instead of 2, hence the review samples being slower than they should be (http://www.techpowerup.com/articles/other/155)">http://www.techpowerup.com/articles/other/155). So did you also test such a card? Reply

    Where is the Assasin's Creed data? Where is the broken line graph for The Witcher showing performance at different resolutions? I've commented on the last several articles on your data analysis and frequently dislike the chosen resolution you use for the horizontal bar graph, but at least you had the broken line graph to compare with.

    With the vast majority of people using 17-19" LCD's with 1280X1024 (especially in the price range of the card being reviewed), it seems kind of strange to me the higher resolutions for 20-22" LCD's are the ones being selected for the large bar graphs. I know the playability difference between 60fps and 70fps is moot, but the trend it shows is very important for those that do not plan on upgrading to a larger monitor and want to know which is the better card.

    For instance the only data we see for The Witcher is at 20-22" resolutions. This single data point shows the AMD card 9% faster than the Nvidia at a just playable (IMO) framerate. As that is likely the average framerate, a 9% difference could be huge when you get into a minimum situation. If I have a 17-19" monitor this data is worthless. Does the trend of AMD being 9% faster hold true at the lower resolution, or does the Nvidia card pull closer?

    And while I'm repeating myself from previous articles, I beg of you, PLEASE PLEASE PLEASE try to keep the colors of the bar graphs the SAME as in the broken line graphs. It is very frustrating to follow the wrong card from bar graph to line graph because the colors do not match up between them.

    Overall good review, there are just these nagging issues that would make the article great.

    I only know two people using 1280x1024 LCDs, and both would consider $130 way too much to spend on any computer component. I'd guess there are more people these days using 17-19" widescreens with 1280x800 or 1440x900 resolution than the 1280x1024 screens, as these widescreens are what has been common in packages at B&M stores or a while now.

    And your point is? Those resolutions you listed are right around the 1280X1024 resolution I was referring too. It's not the height/width of the monitor that matters with these cards, it is the overall pixel resolution that can have differences between them. A 1280X1024 uses 1.3 million pixels per screen. A 1440X900 uses almost exactly the same number of total pixels, so you could directly compare the results unless the video card had some weird resizing issues. A 1280X800 uses 1.0 million or about a quarter less so this difference could be even larger between the cards than in my original example. Reply

    For $130.00 I would not be disappointed with that card. Then you consider it to be somewhat cheaper on newegg maybe as low as $100.00 and you got yourself a bargain, overclock it a little or buy an OC version even, not too shabby. Reply

    I jumped to "Final Words" and boom - no info on 4830 but right into steering people to an Nvidia card. That's so Anandtech. Reply

    Actually what Derek says is it's shop around and get the best price between the two. If there is in fact a $20 to $30 difference then get the 9800gt. If not then get the 4830.

    Performance is about the same and right now you can get a 9800gt for $100 after rebate. (for $110 get it delivered with a copy of COD4 included)

    This doesn't even consider the power advantage of the 9800gt. Assuming you leave your PC on all the time then that little 14 watt idle difference adds up. At the 20 cents per KwH I pay here in Long Island, NY the 9800gt would save me about $24.50 a year. So personally, I would definitely get the 9800gt unless I could find the 4830 for a decent amount less then the 9800gt.

    Didn't really notice it the first read through and most of the time I don't concur with bias allegations.

    However it seems in this case the paragraphs could have been rearranged to 1-4-5-2-3-6 (no rewording necessary) and the conclusion would have said the same thing, only focusing a bit more obvious on the product at hand than what a great deal the nvidia card is.

    thats actually a good suggestion. done. Reply

    "Based on the information we know about the GPU, the 4830 is clearly just an RV770 with one SIMD disabled."

    Don't you mean two SIMD cores?
