Upgrade GPU or Memory?

[MCpliers]

Hello, I have a Z440, w/E5-1620V4 64gs memory and a GTX1080.

Workstation is mostly used for Blender3D modeling. I'm just wondering what is a better upgrade path for me to take, I have 2 choices, ether, upgrade my CPU to a E5-1650V4 or upgrade my memory from 64gbs to 128gbs.

@MCpliers, Welcome to our HP User Forum!

The processor upgrade you proposed looks to me like the path to take: the E5-1650 v4 gets you: 4 more CPU threads (12 vs 8), 1.54 x faster CPU speed (6 x 3.60 GHz vs 4 x 3.50 GHz), and 0.20 GHz higher turbo clock speed (4.00 GHz vs 3.80 GHz), among other advantages the E5-1650 V4 brings to your PC. And for the same 140 watt TDP.

According to PassMark the difference between the two processors as expressed in "CPU Mark" performance scores is considerable: 11465 vs 7444 as seen here: https://www.cpubenchmark.net/compare/Intel-Xeon-E5-1650-v4-vs-Intel-Xeon-E5-1620-v4/2838vs2777.

Hope this was helpful.

Blender3D is slowly making more and more of it's modules multicore capable if you use these modules then upping your CPU core count will show large improvements, for those parts that are not multicore capable a faster CPU overall speed (IPC) will show improvements

in this case i also agree that a faster CPU with more cores will provide a performance increase over a ram upgrade

as long as your projects  are not requiring more physical ram than what you currently have

if however the projects are using more and having to swap code to disk then i would increase ram first

last, blender 3d can in some cases use the video card (GPU) for rendering depending on what your current card is upgrading that may show a better performance increase than doing a CPU upgrade however this will cost quite a bit more than a CPU upgrade
