Intel teased a dual-core Clover Trail+ earlier this year at CES 2013, and now it's revealed the rest of the story at MWC 2013 on the new Atom-based mobile processors. While based on the same 32nm architecture of the previous Medfield generation, the new Z2580, Z2560 and Z2520 chips will sport two 2.0GHz, 1.6GHz and 1.2Ghz CPU cores, respectively, along with two PowerVR SGX 544 GPU cores. That should make the new chip a lot more competitive, performance-wise, though battery life may suffer next to 28nm chips from the likes of Qualcomm. Still, Intel says that the new chips will burn less juice at idle than Medfield, meaning battery life may vary widely depending on usage.
On the radio side, Intel's bringing support for 42Mbps DC-HSPA+ along with 11.5 Mbps HSUPA cat 7, but still no LTE on a CPU for now. However, it also launched its new XMM 7160 LTE radio as a separate chip, supporting 15 LTE bands along with HSPA+ and saying that it'll appear on its upcoming 22nm SoC chips by the end of the year. Finally, to show off all this, Intel flaunted a new reference design for the Z2580 CPU, featuring 2GB of RAM, a max 256GB(!) of NAND, WUXGA support (1,920 x 1,200) and a rear 16-megapixel camera -- and hopefully, a large battery.
