As a programmer who wants to write decent performing code, I am very interested in understanding the architectures of CPUs and GPUs. However, unlike desktop and server CPUs, mobile CPU and GPU vendors tend to do very little architectural disclosure - a fact that we've been working hard to change over the past few years. Often times all that's available are marketing slides with fuzzy performance claims. This situation frustrates me to no end personally. We've done quite a bit of low-level mobile CPU analysis at AnandTech in pursuit of understanding architectures where there is no publicly available documentation. In this spirit, I wrote a few synthetic tests to better understand the performance of current-gen ARM CPU cores without having to rely upon vendor...
