What is the Difference Between Apple A4 and NVIDIA Tegra 2?
🆚 Go to Comparative Table 🆚The Apple A4 and NVIDIA Tegra 2 are both System-on-Chips (SoCs) designed for handheld devices, but they have some key differences in terms of performance, cache, and instruction sets. Here is a comparison between the two:
Apple A4:
- Release Date: March 2010
- First Device: iPad
- Other Devices: iPhone 4, iPod Touch 4G
- ISA: ARM v7 (32bit)
- CPU: ARM Cortex A8 (Single Core)
- CPU's Clock Speed: 1.0 GHz
- GPU: PowerVR SGX535
- GPU's Clock Speed: Not Revealed
- Cache: 512kB L2 cache
NVIDIA Tegra 2:
- Release Date: Q1 2010
- First Device: LG Optimus 2X (first mobile deployment)
- Other Devices: Motorola Atrix 4G, Motorola Photon 4G, LG Optimus Pad, Motorola Xoom, Motorola Electrify, Lenevo ThinkPad Tablet, Samsung Galaxy Tab 10.1
- ISA: ARM v7 (32bit)
- CPU: ARM Cortex-A9 (Dual Core)
- CPU's Clock Speed: 1.0 GHz – 1.2 GHz
- GPU: NVIDIA GeForce (8 cores)
- GPU's Clock Speed: Not Revealed
- Cache: 1MB L2 cache
In terms of performance, NVIDIA Tegra 2 generally outperforms Apple A4 due to its dual-core CPU and larger L2 cache. However, Apple A4 supports the NEON instruction set, while Tegra 2 does not.
