Intel launches Z2500-series Atom chips for smartphones

Earlier this week Intel launched Clover Trail+ platform, comprised of three Atom Z2500 series system-on-a-chips, Intel XMM 7160 LTE modem, and a reference smartphone design. The new platform is still based on 32nm technology, but it offers quite a few benefits over Medfield platform, that was introduced last year. According to Intel, Atom "Clover Trail+" products have up to 2 times better CPU performance and up to 3 times better graphics performance than Medfield counterparts. Z2500-series processors also support faster memory, higher-resolution front and back cameras, larger internal storage, and the latest version of Android, codenamed Jelly Bean.

New Clover Trail+ Atoms are Z2520, Z2560 and Z2580. These SoCs have two CPU cores with HyperThreading, which allows them to execute 4 threads at once. The Z2520, Z2560 and Z2580 chips also support Burst Technology, and can operate up to 1.2 GHz, 1.6 GHz and 2 GHz respectively. All processors have 512KB L2 cache per each core, work with LPDDR2-1066 memory, and integrate PowerVR SGX544MP2 Graphics Media Accelerator. The graphics unit supports frequency boost, and can be clocked up to 300 MHz for the Z2520, and up to 400 MHz and 533 MHz for the Z2560 and Z2580. In addition to the GPU, the SoC contains video encoder and decoder units, that provide 1080p video stream encoding and decoding acceleration at 30fps. Both units can handle H.263, H.264 and MPEG4 video formats, and the decoder also works with VC1 and WMV9 video. The maximum resolution of the Clover Trail+ display controller is 1900x1200. Clover Trail+ SoC includes video image signal processor unit, that supports primary camera with resolution up to 16 megapixels and 1080p x 30fps video capture, and secondary camera with resolution up to 2 MP. Other embedded components are image enhancement unit, crypto engine, and a handful of communication interfaces.

The first smartphone product, based on the Clover Trail+ platform, was announced last month at CES show. Lenovo IdeaPhone K900, which is planned for the second quarter 2013, will come with 5.5 inch screen and Z2580 microprocessor. ASUS and ZTE also announced support for the new platform.

Details of new Clover Trail+ products are provided below:

Atom Z2520 2 4 1.2 GHz 1 MB 300 MHz LPDDR2-1066
Atom Z2560 2 4 1.6 GHz 1 MB 400 MHz LPDDR2-1066
Atom Z2580 2 4 2 GHz 1 MB 533 MHz LPDDR2-1066
