In de laatste uitgave van de Intel Developer Update is een interessant stukje te vinden over Beyond AGP 4x, de opvolger van AGP 4x. Deze nieuwe standaard (?) moet backwards compatible zijn met AGP 4x en de dubbele bandbreedte leveren :
Accelerated Graphics Port (AGP) is an interface that dramatically improves the processing of three-dimensional (3D) graphics. However, today's AGP interfaces will soon have difficulty meeting the high levels of performance that will be required by upcoming applications. These applications include games, 3D graphics animation, mechanical design automation, digital content creation, and video editing.
One issue for handling these applications is increased bandwidth for data traffic. Another, more complex issue is the potential need for isochronous mode operations. To address these issues, initiatives are already in process for a more advanced form of AGP. In particular, Intel is working on an evolutionary initiative called Beyond-AGP4X.[break]Na dit verhaaltje gelezen te hebben, ben je natuurlijk erg beniewd wat deze wannabe standaard moet kunnen, hieronder een samenvatting:[/break]Twice the AGP4X bandwidth, achieved through the use of a new signaling scheme. Relaxation of ordering rules in order to more efficiently process graphics system traffic to and from system memory. Limiting the transaction size of data to the graphics subsystem in order to enable efficient use of the interface. Simplification of the interface usage model, which includes removing the notion of high-priority transactions. The usage model simplification also includes using an alternate, lower performance mode of transaction request generation (called PIPE) by the graphics subsystem. Providing a defined mechanism to enable high-performance cache coherent transactions on the interface. Specifying an optional infrastructure that supports isochronous data streaming on the interface.
