To all appearances the Radeon HD 4830 is a very good product. Of course, it is slower than the Radeon HD 4850 due to the cut-down configuration of the RV770 core – the difference amounts to 10-17% depending on the display resolution. But this is a very small loss considering the potential of the RV770 chip.
The Radeon HD 4830 is 100% worth its price which is below $150. You can get a detailed picture of its performance from our summary diagrams.
At a resolution of 1280x1024 pixels the Radeon HD 4830 loses eight out of the 17 tests to the GeForce 9800 GT but only in three tests it is indeed far slower than its opponent. Moreover, the GeForce 9800 GT could not provide a playable frame rate in S.T.A.L.K.E.R. Clear Sky and Crysis, either. And its advantage in Tomb Raider: Legend can only be seen in numbers but not in practice.
It’s about the same at 1680x1050: the Radeon HD 4830 has nine wins and eight losses, three of which are the above-mentioned S.T.A.L.K.E.R. Clear Sky, Crysis and Tomb Raider: Legend. Spore is the game where the Radeon HD 4830 is superior even to a naked eye.
The Radeon HD 4830 is not really meant for playing at 1920x1200 just because people who buy $100 graphics cards do not usually have an appropriate monitor. However, it can deliver a playable frame rate at that resolution, too, in a number of games including Dead Space, Enemy Territory: Quake Wars and BioShock. It now loses only six tests to the GeForce 9800 GT but wins 11.
Thus, the Radeon HD 4830 fulfils its purpose which was to fill in the gap between the Radeon HD 4850 and HD 4670. The card does its job well, being 100% worth its price. It may be slower than the GeForce 9800 GT in some games but the latter is based on an outdated architecture and doesn’t feel good in modern computations-heavy games. The Radeon HD 4830 is unlikely to become a sensation like the Radeon HD 4850, yet it is quite capable of becoming the best inexpensive gaming card featuring all modern multimedia capabilities.
