Knights Hill


Joel Hruska, ExtremeTech, Intel’s third-generation Xeon Phi to use 10nm technology, deploy second-generation Omni-Path fabric, here.

Future versions of the core will likely expand both the onboard memory pool (16GB is expected for Knights Landing; Knights Hill could pack 32GB or more), add additional bandwidth, and likely increase the interconnect performance between the CPU and the associated MIC. Intel might push its AVX standard up as high as 1024-bit registers, but this is unclear and likely depends on trends in the HPC community. Adding wider registers might seem like a simple way to boost performance, but it’s subject to the same diminishing returns as everything else. The current AVX specification allows for extensions of up to 1024 bits in length, however, so Intel has left this option open in the long term.
