OMAP4 on LG Optimus 3D Comes Out With Flying Colors
“The big news is that we spent some time using and benchmarking LG’s Optimus 3D. The Optimus 3D is the first smartphone to use TI’s OMAP 4430 SoC. Like NVIDIA’s Tegra 2, the 4430 integrates a pair of ARM Cortex A9 cores behind a shared 1MB L2 cache. The OMAP 4430 differs from Tegra 2 in three key ways:
1) TI integrates ARM’s Media Processing Engine (MPE) enabling NEON support
2) TI has a dual-channel LPDDR2 memory controller (Tegra 2 only has a single-channel memory controller).
3) The OMAP 4430 integrates Imagination Technologies’ PowerVR SGX 540 running at ~300MHz, NVIDIA uses its own GeForce GPU.
We measured competitive CPU performance from the Exynos in the Galaxy S II, however the GPU performance was a bit behind the Tegra 2.
It’s sort of nice to have so many different SoCs available at the same time. TI’s OMAP 4430, Samsung’s Exynos 4210, NVIDIA’s Tegra 2 AP20H and Qualcomm’s upcoming MSM8660. Right now it looks like the OMAP 4430 may be the best performer out of them all, however it remains to be seen what Qualcomm’s Adreno 220 will bring to the table when the MSM8660 ships later this year.”
