- The A4 and the A8: secrets of the iPad's brain
But it turns out that the the A4 is a 1GHz custom SoC with a single Cortex A8 core and a PowerVR SGX GPU. [...] In all, the A4 is quite comparable to the other Cortex A8-based SoCs that are coming onto the market, except that the A4 has even less hardware. The iPad doesn't have much in the way of I/O, so the A4 itself can do away with the I/O that it doesn't need. In contrast, the typical Cortex A8-based SoC has more I/O hardware than a mobile phone can use, because you never know what customers will need which interface types.
La révolution du microprocesseur d'Apple ? Tout dans la carte graphique, et un processeur standard dégraissé. Merci Steve pour toutes ces attentions. Laisse-moi te lécher les pieds.
