mpeg2 to AVC transcoding performance comparison between E3-1285L v4 and E3-1585L v5

Hello, 

MediaSDK 2017

Platform: Centos

from this document:

https://software.intel.com/sites/default/files/managed/85/7c/Intel-Xeon-Processor-E3-1500-v5-Perform...

at the bottom of it I see: "1 Number of real time threads transcoded simultaneously: 18 on both E3-1285Lv4 and E3-1585Lv5 using 1080p30 20Mbps streams and Intel MediaSDK (Target Usage 7). Note: for AVC, performance is the same as E3-1285v4"

But using "sample_multi_transcode" and "metrics_monitor" tools I see a different results. What could be the reason for this? I expected better performance from E3-1585Lv5 actually, but the test shows slightly different results in favor to 1285L.

Used progressive input source:
