iPhone 4, GPU con supporto DirectX 10 e OpenGL 3.2

Il prossimo iPhone supporterà l'alta definizione e il rendering 3D. Imagination Technologie, fornitore ufficiale delle GPU per iPhone, ha infatti presentato la nuova GPU PowerVR SGX545. Un modello di processore grafico che supporta le librerie DirectX 10.1, OpenGL 3.2 e OpenCL 1.0, e che pare essere in grado di gestire fino a 40 milioni di poligoni al secondo a 200Mhz – contro i 28 milioni dell'attuale iPhone 3GS.
