No processor, CPU or GPU, ever reaches 100% linearity with clock speeds unless memory speeds increase by the same percentage. This isn't just bandwidth but also (often more importantly) latency. GPUs are obviously better at hiding latency than CPUs at that but they're not necessarily perfect...

But do the games look exactly the same on low-end vs. high-end devices? It's just like PC games supporting a spectrum of GPUs, theoretically all fluidly, through a variety of graphical settings. It's a matter of how many people want their games to present all the latest whiz-bang effects (probably a lot given how motivated vendors are in pushing smartphone GPU performance) vs how many people just want their games to run (which is no doubt significant especially for first-time smartphone buyers) and how much more that 1st group is willing to pay to support the expenses of envelope pushing GPUs. Ideally TI would have SoCs to target both audiences.
