Texas Instruments OMAP 4430 vs Texas Instruments OMAP 4460

Texas Instruments OMAP 4430

The Texas Instruments (TI) OMAP 4430 is a SoC with two ARM Cortex-A9 cores including NEON SIMD engine, two Cortex M3 cores (to save power), a PowerVR SGX540 graphics card (304-365 MHz) and a dual channel LPDDR2 memory controller (max 400 MHz).

Texas Instruments OMAP 4460

The OMAP 4460 is a fourth generation SoC (System on Chip) developed by Texas Instruments (TI) for use in mobile phones and tablets. The 45 nm chip includes dual ARM Cortex-A9 CPU cores running at 1.2 GHz up to 1.5 GHz on an ARM v7 instruction set and ARM NEON SIMD (Single instruction, multiple data) engine. 

The SoC integrates an SGX540 GPU from PowerVR clocked at 384 MHz, which can utilize the same 400 MHz dual-channel LPDDR2 memory controller as the two core processors. Compared to the OMAP 4430, the 4460 is clocked higher on both the CPU and GPU.

The OMAP 4460 is found in a small number of tablets and smartphones, most notably the Samsung Galaxy Nexus and the Amazon Kindle Fire HD 7. In terms of raw processing and GPU power, the SoC is more in line with the Nvidia Tegra 2 than the Tegra 3. The integrated SGX540 is an older generation of graphics that has been largely superceded by the much more powerful SGX543 as found in the third generation iPad.
