What is the Difference Between Apple A4 and Qualcomm Snapdragon S2?

The Apple A4 and Qualcomm Snapdragon S2 are both System-on-Chips (SoCs) designed for handheld devices, but they have some differences in terms of CPU architecture, GPU, and performance. Here is a comparison between the two:

Apple A4:

• CPU: ARM Cortex A8 (Single Core)
• CPU's Clock Speed: 1.0 GHz
• GPU: PowerVR SGX535
• L1 Cache: 32kB instruction, 32kB data
• L2 Cache: 512kB
• First Device: iPad
• Other Devices: iPhone 4, iPod Touch 4G
• Manufacturing Process: TSMC's 45nm

Qualcomm Snapdragon S2 MSM8255:

• CPU: Qualcomm Scorpion (Single Core)
• CPU's Clock Speed: 800 MHz – 1.4 GHz
• GPU: Qualcomm AdrenoTM 205
• L1 Cache: Not Known
• L2 Cache: Not Known
• First Device: HTC Vision
• Other Devices: LG Optimus7, HTC Desire, HP Veer, HTC Ignite, HTC Prime, Sony Ericsson Xperia Pro, Motorola Triumph
• Manufacturing Process: TSMC's 45nm

In terms of performance, both SoCs have comparable features, with the Snapdragon S2 potentially having a faster clocking frequency. The GPU section shows that Adreno 205 is known to outperform PowerVR SGX535. The A4 may have a higher IPC (Instructions per Clock) than the Snapdragon due to better core architecture, larger caches, or a faster memory bus.
