Hp z820 bad experience

[Muhammad_Usman0]

Hi everyone
I need help
I rendered an Adobe After Effects project at hp z820 and it took one and half hour to render.
And when rendering the same project on hp i7 4th gen, it took twenty minutes
What is the reason for this?
While HPZ 820 has more cores and i7 has less
Hpz 820 specs
Processor: w2687 (2) processor ( total 16 cores 40 mb cache 3.0)
56 gb ram ddr3
Gpu: Nvidia Gtx 760 ( 2
gb ddr5)
Hdd: 240 Ssd
I7 specs:
4790 processor 3.6 (4 cores 6mb cache)
12 gb ram ddr3
Gpu: Nvidia quadro 600(1gb)
Hdd: 120 gb ssd

the cause most likely is cpu based, the newer i7 cpu has some instructions such as AVX2 and FMA3 instructions

which after effects supports that the xeon w26xx line of cpus lack

also, is your w2687 a v1 (Sandy Bridge EP) or v2 (Ivy Bridge EP)

i don't think avx2/FEMA3  were supported until the xeon v3 line of cpu's
