Here is Epic Citidel running on an TI Omap 4430 w/ PowerVR SGX540 GPU:

It's impressive that so much performance can be squeezed out of last gen's GPU. I'm curious to know how much of the CPU is being used in this demo. I'm guessing that the static nature of this demo has the GPU handling 99% of the tasks.

It's even more impressive considering that the iPhone4's SGX535 is capable of running this smoothly. Methinks that game developers haven't begun to take these chips to their limits.

I'm amazed to think of what the A5's SGX543MP2, or the Exynos 4210's Mali400MP4 can do seeing these visuals. These are true current gen GPUs capable of multiplying the performance of the SGX540. At the very least, in game effects could be multiplied with much more shader saturation over the entire scene.

Here is the same demo running on the SGX543MP4 of the Sony NGP:

Notice the particle effects, rich shadows, and extended geometry of the non-player characters, far vanishing point, god rays, etc. Quite impressive.

It would be worth while for the chip manufacturers to hire some developers to create compelling demos to show off the power of these chips rather than dry spec sheets.
