What is the Difference Between Apple A4 and A5 Processors?
🆚 Go to Comparative Table 🆚The Apple A4 and A5 processors are both system-on-a-chip (SoC) designs targeting handheld devices. They share some similarities, but there are key differences between the two:
Apple A4:
- Single-core ARM Cortex-A8 processor
- 1.0 GHz base frequency
- 512 KB cache memory
- PowerVR SGX535 GPU with 2 shading units
- Manufactured using 45 nm lithography
Apple A5:
- Dual-core ARM Cortex-A9 processor
- 1.0 GHz base frequency
- 1 MB cache memory
- PowerVR SGX543MP2 GPU with 8 shading units
- Manufactured using 45 nm lithography
The main difference between the two processors is the number of cores in the CPU, with the A5 having two cores compared to the A4's single core. This results in the A5 being up to two times faster than the A4 in terms of CPU performance. Additionally, the A5's GPU is significantly more powerful than the A4's, with up to nine times the graphics performance. The A5 also has a larger cache memory, which contributes to its overall performance advantage over the A4.
