Memory bandwidth is a critical to feeding the shader arrays in programmable GPUs. In this report, we show that memory is an integral part of a good performance model and can easily impact graphics by 40% or more. The implications are important for upcoming integrated graphics, such as AMD’s Llano and Intel’s Ivy Bridge – as the bandwidth constraints will play a key role in determining overall performance.
