- dantle 8y agoSkylake was a reasonably big core architecture upgrade (a "tock" in Intel terminology). Several new instructions (XSAVE, AVX512, etc.) were introduced. Perhaps you meant Broadwell?
- wtallis 8y agoConsumer Skylake and derivatives didn't get AVX512; that's reserved for the server parts that arrived two years later.
- chx 8y agoIt's been benchmarked that from Sandy Bridge to Kaby Lake the IPC only grew 20% https://www.hardocp.com/article/2017/01/13/kaby_lake_7700k_vs_sandy_bridge_2600k_ipc_review/4 https://www.hardocp.com/article/2017/01/13/kaby_lake_7700k_v... but the power efficiency has brutally increased: This is a 35W CPU in 2011 https://browser.geekbench.com/processors/381 https://browser.geekbench.com/processors/381 and this is an Y (4.5-7W) CPU from 2017 https://browser.geekbench.com/processors/1822 https://browser.geekbench.com/processors/1822 .
