I was recently impressed by the good performance of the ATI Mobility Radeon HD 4330, and finally I got some benchmarks of the Mobility 4530 and 4570. The data belong to the benchmarking effort I coordine, so they are user-submitted benchmarks: there are different processors, operating systems, driver versions… Sure, it’s not the typical lab-controlled benchmark you are used to read in sites such as AnandTech, Tom’s Hardware and so, but they help assessing the relative gaming performance of these cards.
The most interesting results are from the Crysis GPU benchmark at 1024×768 and Medium details. Here you have a comparison with other better known cards. The GeForce 9600M GT in the chart is the GDDR3 version and is overclocked (600, 1500 and 840 MHz for core, shaders and memory, respectively; stock clocks are 500, 1250 and 800), so it is a quite powerful card in its class:

You can look at the complete benchmark chart to see all available data.
A few remarks:
- The Mobility Radeon HD 4330 found in the Dell Inspiron 1545 (US, UK) clearly belongs to a different class than the 3450 and other similar cards such as the GeForce 9300M GS. The difference in the result is likely due to the different memory (GDDR3 vs DDR2) more than to other specs of the cards, but at the moment all 4330 cards I have seen are GDDR3 and all 3450 are DDR2.
- The Mobility Radeon HD 4570 found in the Dell Studio 1555 (US, UK) is comparable to a 9600M GT GDDR3 at stock clocks and is probably superior to the DDR2 version. The high-performing processor in the laptop (an Intel Core 2 Duo T9550 @ 2.66 GHz) could contribute to the high scores, but the influence of the processor usually is only significant at low demanding settings (800×600 or lower and low detail). This particular user plays Crysis at 1280×720, Medium Shadows and the remaining settings at Low. Update: there are some videos at Youtube showing gameplay in Crysis, Half Life 2 Episode 2, Unreal Tournament 3 and Sins of a Solar Empire.
- The Mobility Radeon HD 4530 found in the HP Pavilion dv6 (US dv6t
, US dv6z
, UK) and dv7t is in the middle, probably at the level of a GeForce 9600M GT DDR2. Update: I have updated the benchmark chart with the Devil May Cry 4 DX9 benchmarks; the results are a bit worse than in Crysis compared to the Nvidia solutions.
- Keep in mind that these are scores of a single game and a few different configurations. Anyway, it is a very popular game with a lot of benchmarks published in the Net, so it is quite informative. If I can get more data I will update this post.
