The article author seems to think that the MT/s number is all that you need to tell the performance of a GPU. This hasn't been the case for 8-10 years now. You can't declare it to be faster without benching it, the theoretical numbers don't reveal much any more. (like comparing a 3GHz Intel to AMD CPU; Intel is much faster today at that clock; AMD was much faster in 2005).
Several PowerVR GPUs in modern phone SoCs (Snapdragon and so on) have higher claimed MT/s numbers but don't even approach the PS3.
The PS3 can also offload a lot of rendering and vector tasks onto the Cell SPUs, so the PS3 has higher effective performance. Games are also optimised for that GPU due to mature drivers and a single target for developers; a PC Gefore 7900 which would be similar hardware actually performs a lot worse on PC ports of those games and so would phone apps.
We'd need to see benches and screenshots before we can confirm this, basically. Ars usualy has higher journalistic standards than this; I'm surprised.
