Intel is gearing up a set of 14nm server chips, including its first Core-based SoC. The x86 giant started sampling in March its 22nm Avoton, a server SoC using the new Atom-based Silvermont core, and it has chips in wireless base stations in field trials.
In 2014 or later, Intel will roll out three classes of server chips using its 14nm technology now being tested in its fabs. Broadwell is Intel's next-generation Xeon and will include a related class of SoCs. Denverton is a set of Atom-based SoCs.
Intel did not say what peripherals it will add to Broadwell beyond to PCI Express and memory controller blocks in Xeon today. However it did note it is adding Ethernet and accelerators to its Atom-based SoCs starting with Avoton.
Intel revealed that Avoton, a.k.a. the C2000, will include eight Silvermont-class 64-bit Atom cores. It also integrates four Gbit Ethernet controllers, four serial ATA 2.0 controllers, two SATA 1.0 controllers, four controllers supporting 16-lanes of PCI Express Gen 2, and support for DDR3 memory. A related SoC for storage systems called Rangely will include a crypto accelerator using Intel's Quick Assist technology.
"We've been shipping samples of Avoton and Rangely since way back in March and launching the chips in the second half of the year," said Diane Bryant, general manager of Intel's datacenter group, speaking in the press briefing.
She claimed Intel's 22nm process sports transistors with 50 percent better performance than the 20nm transistors at TSMC. "When [TSMC ships 20nm parts] we will be shipping [products based on] our 14nm transistors," she added.
