The OMAP 4470 system on chip (SoC) is the latest production from Texas Instruments (TI) 4th generation of OMAP processors. First presented at Computex 2011, the TI OMAP 4470 features four CPU cores:
- a dual core ARM Cortex-A9 running at a maximum of 1.8GHz (20% faster clock than the OMAP 4460 at 1.5 GHz)
- assisted by two Cortex-M3 cores running at 266MHz to handle less computationally intensive tasks (2D animations, touch interaction) and increase power efficiency.
The graphic processor is a PowerVR SGX544 GPU running at 384MHz, up 25% from the 304MHz of the SGX540. (Apple A5 CPU in the iPAD 2 uses a dual core version of the SGX543 GPU).
Like in older OMAP 4 processors, the DRAM memory controller offers a dual 32-bit DRAM channel, but it has been optimized on the 4470 to support LPDDR2-466 memory, which is 15% faster than in the 4460 and gives a memory bandwidth up to 7.5 GB/s.
While Archos G9 tablets were using latest upgrade OMAP 4430 and 4460, there is good chance that the new Archos G10 tablets run on the OMAP 4470 (see GLBenchmark leak) and would be one of the first products…
