Apple claims that it is twice as fast and has twice the graphics power compared to its predecessor the Apple A5. The A6 is said to use a 1.3 GHz custom Apple-designed ARMv7 based dual-core CPU,[6] called Swift, rather than a licensed CPU from ARM like in previous designs, and an integrated triple-core PowerVR SGX 543MP3 graphics processing unit (GPU) with the same performance as the previous Apple A5X processor found in the third-generation iPad. The SGX 543MP3 is running at 266 MHz. The A6 chip also has 1GB of LPDDR2 SDRAM made by Elpida. Compared to the iPhone 4S, which had only 512MB of LPDDR2 SDRAM. |

There are two variants of the A6 system-on-a-chip:
- S5L8950 (A6), used in all variants of the iPhone 5 and iPhone 5c.
- S5L8955 (A6X), used in all variants of the iPad (4th generation).
