- 110W Max Board Power
PC Perspective feel that the HD 4830 is a great addition to the mid-range graphics market:
"AMD's latest entry into the graphics card market is a great addition to the mid-range market offering up tremendous gaming performance for less than $130 and putting NVIDIA's G92-based GeForce 9800 GT in a tight spot for the first time since its introduction. Both card offerings will most likely provide a good gaming experience, and I do have to mention the CUDA and PhysX support of the NVIDIA GPUs, but in the end I still side with raw performance and think the HD 4830 512MB card will be the better option."

AnandTech compared the HD 4830 to the 4870, 4850, 4670, GeForce GTX 260 core 216, GTX 260, 9800 GTX+, and 9800 GT cards:
"The performance gap at the $120-$130 price range for a target resolution of 1680x1050 between the 9800 GT and the 4830, in practical terms, isn't that much. Both are playable in the majority of games we tested. The exceptions are Age of Conan and Crysis which can get by at 1280x1024 (or with decreased quality settings). While you may get a smoother experience on the AMD card in general, you won't get a significantly more playable experience in most cases in the games we tested." [AnandTech | AMD Radeon HD 4830]
HardwareZone tested compared 3 HD 4830 cards to the 4850, 4670, GeForce 9800 GT, and 9600 GSO cards:
"... how does it compare against the GeForce 9800 GT? It is very close, but if you were an ATI fanboy, you would probably say it is perhaps the equivalent of an overclocked GeForce 9800 GT (our results did show that it bettered the factory-overclocked Zotac card in some tests), whereas if you belong to the green camp, you think, "Yeah, it's about as good as the GeForce 9800 GT". Simply put, there is very little to separate the two cards, but we think it's fair to say that the performance of the 4830 falls quite neatly between that of a reference-clocked GeForce 9800 GT and an overclocked one."

HotHardware.com gives its Recommended award to the Radeon HD 4830:
"The new ATI Radeon HD 4830 performed right in line with its position in the market--the card was clearly faster than the more affordable Radeon HD 4670 and a bit slower than the pricer Radeon HD 4850. In comparison to NVIDIA's offerings, the 4830 is typically faster than the GeForce 9600 and about on par with or somewhat slower than a GeForce 9800 GT."

FiringSquad.com compared the 4830 with the Radeon HD 3850, HD 4850, GeForce 8800 GT, 9600 GT, and 9800 GTX cards:
"Even if ATI doesn't improve their performance in Far Cry 2, the Radeon 4830 is still an excellent overall performer, besting GeForce 9800 GT in Crysis and drawing even in STALKER: Clear Sky. Its superior 8xAA performance is icing on the cake, putting it over the top if you crave the crispest visuals. NVIDIA still doesn't have an answer to this particular problem, even with their latest Big Bang II beta driver. This is ATI's chief advantage over NVIDIA this generation."

If you have your sights set on a 9800 GT, but would also like to try an ATI graphics card, the HD 4830 wouldn't disappoint.
