need some assistance interpreting values

[i3roly]

hi all,

i'm currently abusing intel's MKL for my program, which scales very nicely and performs well.

however in the past few days (or maybe a week), i've noticed that my 12 core mac pro 5,1 (2 x5690s, 128gb ram) is getting its ass beat very badly by my 2020 i9 macbook pro 16" (9980, 64GB ram) on the same inputdata, using the same program, with the exact same compilation.

whilst i understand AVX and newer architectures help, i am doubtful this explains the massive gap in performance. often my mac pro would be a little faster (not much, hey it's got 50% more cores at higher clocks) but not by much, which is more along the lines of what i expect.

i am posting my PCM gif of when my program is running, along with an istat screenshot. i am hoping you guys can help me gain some insight here.

it seems some of the cores on one CPU are very low temp, which seems unusual. also shouldn't IPC be over .5? if turbo is 3.76 it seems to be sitting exactly halfway. it seems weird.

this seems like something is wrong. it is losing badly

PCM TEMP reports the temp headroom to TjMax frequency. The low "TEMP" headroom value means the temperature is high. Please check if the fans are working fine.

The x5690s processor does not support AVX. The MKL takes advantage of AVX therefore it can explain the higher performance of Core i9 9980 (despite having fewer cores).
