Specifications of embedded ValleyView processors
Future Intel Atom systems on a chip (SoC), codenamed "ValleyView", are expected to bring several big performance enhancements. According to numerous leaks, the processors will utilize "Silvermont" microarchitecture with out of order execution, which will significantly improve CPU performance. Graphics Processing Unit, integrated on these parts, will be replaced with 7th generation (Ivy Bridge) GPU, that should also improve graphics performance. On top of that, some ValleyView SKUs will double the number of cores on a chip from 2 to 4. "ValleyView" SoCs will target several markets, including mobile, tablet, embedded and desktop ones. Processors for each market will be based on its own custom ValleyView core, that may incorporate additional components and/or have extra features. For instance, mobile ValleyView chips will support C7 low-power state, that won't be available on desktop parts. Embedded Atom processors will be based on ValleyView-I variation of the core. Some details of these products, such as operating frequency and the number of cores, leaked last August. We now have more information on these products.
Previously leaked information revealed 4 SKUs, operating in extended temperature range, and 4 standard temperature SKUs, including one ValleyView-T model for tablets. The tablet-oriented SKU has been scrapped by Intel, but the specifications of the remaining 7 models haven't changed.
Standard temperature parts will operate from 0°C to 90°C, or from 0°C to 100°C, depending on model. They will integrate dual-channel memory controller, as well as 1MB L2 cache per each pair of cores. Intel will offer three SKUs, all running at 1.7 GHz or faster. One of the three SoCs will support Burst technology, and have 1.9 GHz or higher maximum Burst frequency. This part will have 4 CPU cores and 12 Watt or lower TDP. Two other SKUs, one dual-core and one quad-core, will have 10 Watt or lower TDP. On-chip GPU on standard temperature SoCs will be clocked at 300 MHz or higher.
Extended temperature SKUs will operate from -40°C to +110°C, and come with 1, 2 or 4 CPU cores. Entry-level SoC will have 1 CPU core, 1.3 GHz - 1.6 GHz clock rate, and GPU, clocked at 400 MHz. Mid-class SKU will have 2 cores, 1.2 GHz - 1.5 GHz frequency, and 533 MHz GPU speed. High SKU will also have 2 cores, and higher 1.5 GHz - 1.7 GHz clock speed. Its graphics unit will operate at 667 MHz. Premium SKU will have 4 CPU cores, 1.7GHz - 2GHz clock speed, and 700 MHz GPU frequency. Integrated memory controller on entry-level and mid SKUs will have only one channel, whereas high and premium SKUs will have two memory channels. All extended temperature chips will fit into 6 Watt or lower thermal envelope. They will incorporate AES instructions and work with ECC memory. Both features, AES and ECC, will not be available on standard temperature SKUs. Some technologies, like Intel 64, VT-x virtualization and NX-bit, will be supported by all ValleyView Atoms.
