Apple A6 vs Broadcom BCM21664T vs Apple A6x

Apple A6

The Apple A6 is a dual-core SoC found in the iPhone 5 with ARM compatible CPU cores. The A6 was developed by Apple and supports the extended ARMv7s instruction set. The clock rate of the CPU is between 800 to 1200 MHz depending on the CPU load. The integrated GPU is a PowerVR SGX543MP3 at 266 MHz.

Broadcom BCM21664T

The Broadcom BCM21664T is an ARM based entry-level SoC for smartphones that integrates two Cortex-A9 CPU cores clocked at up to 1.2 GHz and a HSPA+ modem with support for 21 Mbps HSDPA and 5.8 Mbps HSUPA. Furthermore, a VideoCore-IV GPU and a video decoder (H.264 1080p capable) and encoder (720p) are built into the SoC.

Apple A6x

The Apple A6x is a dual-core-SoC (System on a Chip) with ARM compatible CPU cores (ARMv7s instruction set). Both can be clocked at up to 1400 MHz depending on the load. It is used in the iPad 4 and compared to the A6 in the iPhone 5, the A6x offers a faster GPU (PowerVR SGX544MP4).

The CPU-Performance of the A6x is similar to the Qualcomm Snapdragon S4 Pro MSM8960T, while the GPU is about as fast as the Adreno 320.
