JCC Erratum Impact On Skylake Xeon Scalable Plus The Patched Assembler

20. Listopad 2019 - 16:29
Last week ago we provided a number of benchmarks looking at the performance impact from Intel's Jump Conditional Code (JCC) Erratum that required a CPU microcode update to mitigate but that comes with a performance hit. At least Intel has pending GNU Assembler patches to help offset that performance hit. In time for last week's articles I didn't have a chance to perform Skylake Xeon Scalable (1st Gen) benchmarks but now here are some metrics alongside Cascade Lake...
