Intel unveils Atom Z650 and Z670 processors

Intel today introduced Oak Trail platform, aimed at tablets and other fanless mobile devices. The platform consists of Atom Z650 and Z670 "Lincroft" microprocessors, coupled with SM35 Express chipset, and supports several popular mobile operating systems, including Android, MeeGo and Windows. Main benefits of "Lincroft" processors over older Atom chips are improved graphics performance, smaller footprint, and longer battery life at similar level of CPU performance. First tablets with the new Atoms will be available in May 2011.

Intel Z650 and Z670 are built on 45nm technology, and include single CPU core, capable of running two threads at the same time. The core includes 512 KB level 2 cache, and provides support for SIMD instructions up to SSE3, and for basic technologies like execute disable bit. More advanced features, such as 64-bit operating mode and Virtualization, are not supported by the Z6xx microprocessors. In addition to one CPU core, the Intel Z650 and Z670 parts integrate Graphics Media Accelerator 600, operating at 400 MHz, and single-channel DDR2 memory controller. Combined maximum power consumption of all Z6xx on-chip components does not exceed 3 Watt. The processors are produced in a small form factor 13.8mm x 13.8mm BGA package. Main difference between Z650 and Z670 models is the clock frequency. The Z650 is clocked at 1.2 GHz, and the Z670 runs at 1.5 GHz.

Like the new Atom microprocessors, Intel SM35 Express chipset also comes in a small form factor 14mm x 14mm package. The chipset supports Serial ATA, up to 4 USB 2.0 ports, High-Definition audio, Secured Digital Input/Output 2.0, and includes HDMI interface with HDCP 1.3.

Atom Z670 is priced at $75 in 1K quantities. Pricing of Z650 CPU and SM35 chipset was not disclosed by Intel.
