Expected to be launched in the second half of 2013, Rangeley will come in various SKUs, with TDPs ranging from 7-8W for the low-end parts to 20W for the top-end models. Full details at CPU World.
Rangeley chips are very similar to Avoton processors, except that they add an Intel Crypto engine. Depending on SKU, the parts incorporate from 2 to 8 Atom cores, clocked up to 2.4 GHz. The cores use Silvermont out-of order microarchitecture, that is expected to be up to 35% faster per clock than existing 32nm Saltwell architecture. A list of CPU features, supported by the cores, includes SSE4 and AES instructions, and VT-x virtualization. Each pair of CPU cores share 1 MB L2 cache. The SoC also has a dual-channel DDR3 memory controller, that supports to 64 GB of DDR3-1600 or DDR3L-1600 ECC memory. Other interfaces, integrated on the SoC, are 4 PCI Express 2.0 controllers with x16 lanes total, SATA, Gigabit, USB and legacy I/O. Overall, the SoC has 2 SATA 3 ports, and 4 of each SATA 2, Gigabit and USB 2.0 ports. Legacy I/O includes LPC, UART, SMBus, SPI and general purpose I/O.
New component in the Rangeley SoC is a Crypto engine, that implements Intel QuickAssist technology. This technology supports several ciphers, including 128-, 192- and 256-bit AES, 3DES, DES and Kasumi. It also provides authentication, public key encryption and a random number generator. Performance of the Crypto block is SKU dependent, reaching 10 Gbps for 128-bit AES (1 KB buffer) encryption for a top-end SKU.
