Early BlackBerry devices used Intel-80386-based processors. The latest BlackBerry 9000 series is equipped with Intel XScale 624 MHz CPU,which makes it the fastest BlackBerry to date. Earlier BlackBerry 8000 series smartphones, such as the 8700 and the Pearl, are based on the 312 MHz ARM XScale ARMv5TE PXA900. An exception to this is the BlackBerry 8707 which is based on the 80 MHz Qualcomm 3250 chipset, this was due to the ARM XScale ARMv5TE PXA900 chipset not supporting 3G networks. The 80 MHz Processor in the BlackBerry 8707 actually meant the device was often slower to download and render web pages over 3G than the 8700 was over EDGE networks.
