Intel recently announced a new Atom-series Z2420 processor aimed at low-cost smartphones. The new System on a Chip will complement the existing Medfield and Clover Trail+ line – which are for higher-performance devices – by being aimed at the low cost phones in developing markets. The Atom Z2420 combines a CPU, L2 cache, GPU, memory controller, cryptography engine, image signal processor, and fixed function hardware used for video encoding and decoding. The chip is designed to be low power and is manufactured on Intel’s 32nm High-k metal gate process technology. According to Intel, the Co-PoP package measures 12 mm x 12 mm making it suitable for the intended smartphone form factor.
Specifications include a single core processor with 512KB of L2 cache running at 1.2 GHz that supports Intel’s HyperThreading, Burst, and low power C6 state technologies. With HyperThreading, it can utilize two threads and with Burst, the processor can dynamically scale frequency to balance power usage and CPU load. The Intel GMA GPU uses PowerVR SGX540 graphics cores clocked at 400 Mhz. It is compatible with OpenGL ES 2.0 and OpenVG 1.1. The GPU is rated at 40 MTS peak polygons and a 2000 MPPS peak fill rate. Additionally, the SoC features hardware that can hardware encode/decode 30 FPS 1080p video in H.264, H.263, and MP4. Further, the hardware can hardware accelerate decoding of VC1, WMV9 but it cannot hardware accelerate encoding of those two additional formats. The Atom Z2420 SoC supports dual channel LPDDR2 memory clocked at 400 MHz. The Image Signal Processor (ISP) can support a 1.2MP and 8MP front and rear cameras. The SoC can support 15 FPS burst capture, video image stabilization, and HD video recording.
Intel has positioned the Atom Z2420 SoC at the Android operating system, and has even built a reference smartphone with the new processor. Acer, Lava, and Safaricom are among the companies lined up to produce future budget smartphones with the new SoC. Unfortunately, Atom Z2420-powered smartphones are not headed to the United States. Intel is sticking to developing markets suchs as India, Latin America, and Africa. Here's hoping next year Intel (finally) feels its mobile (smartphone) hardware is ready to compete with the ARM giants and that it pushes for Atom-powered smartphones in additional countries (including the US). Until then, you can find more information on the current generation Z2420 in the press release (PDF).
