Took an deeper look on those >1000 spec_power intel results.They had disabled few xeon features whom might not help for spec_ops but power consumption.
AMD had just disabled Hardware Prefetch. Looking at other intel testings those features are allways disabled for benching.System Under Test Notes
* Each JVM instance was affinitized to a socket.
* Using the local security settings console, "lock pages in memory" was enabled
for the user running the benchmark.
* C1 Enhanced Mode Enabled in BIOS.
* Hardware Prefetch Disabled in BIOS.
* Adjacent Cache Line Prefetch Disabled in BIOS.
* Intel EIST support Enabled in BIOS.
* Fan speed control Mode 4-pin (server) in BIOS
Edit: Never mind Adjacent Cache Line Prefetch is disabled by default
