Broadcom BCM28155 vs Texas Instruments OMAP 4460 vs Texas Instruments OMAP 4470

Broadcom BCM28155

The Broadcom BCM28155 is a Dual-Core Cortex-A9 SoC with an integrated VideoCore-IV graphics card and UMTS/HSPA+ (no LTE). The two ARM Cortex-A9 processor cores run with up to 1.2 GHz. The integrated modem supports UMTS and HSPA+ but no LTE.

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 The integrated SGX540 is an older generation of graphics that has been largely superceded by the much more powerful SGX543 as found in the third generation iPad.

Texas Instruments OMAP 4470

The OMAP 4470 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 1.3 GHz up to 1.8 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 277 - 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 4470 is clocked higher on both the CPU and GPU.
