Question Moving from i7 4930k (2011 Platform) to Ryzen 7 (1700X,1800X)

Greetings!

I am thinking about upgrading my rig which is currently based on i7 4930k towards Ryzen 7 1700X or 1800X model.

Current config is:
i7 4930k on Gigabyte X79-UD3 with 16GB (4x4G DDR3 1866, GTX 1060 6GB, 2 SSDs (Samung 850 Pro for 256Gb and Intel 520 for 180 Gb) a few WD HDDs (2x640Gbs, 2x1Tb). All is powered by 750W PSU.

Usual use-cases for my rig are
  • Developing in Visual Studio
  • Virtualization via VirtualBox or VMWare
  • Some 3D in Blender and 3DMax
  • AutoCAD
  • Sometimes gaming

According to Geekbench 4 results for example average (not overclocked) i7 4930k scores:

single core: 3500 multicore: 20000

average Ryzen 7 1800X (not overclocked) scores:

single core: 4200 multicore: 22000

As for Cinebench R15 results, i'm getting from 970 - 1040 for MC and 100 in SC on my i7,
and Ryzen 7 gets much better performance in Cinebench R15.

It looks like not a big difference between 4930k and R7 in Geekbench and pretty big in Cinebench.
So I'm curious will I gain any significant performance boost for my use-cases from such switch?

TTL can jump in and give the best advice here, but I think if you were adamant on an upgrade you are making the right choice.

Since gaming is a minor factor for you, Ryzen will shine more for you in application oriented use. I am just basing my opinion on reviews as I dont own one, but for the most part, they do excel very well.

I would get a better cooler and OC the current CPU. Seem like the better option, and then wait for Ryzen 2, or a Threadripper

Going from Ivy to Broadwell E "like" IPC is going to be quite an upgrade fella.

Plus you gain two cores. If it were a 5820k I would be more hesitant, but Broadwell E "like" IPC is quite a big jump.

As for overclocking? if the guy needs ultimate stability then that may be an issue. 4930k did not overclock very well compared to the 3970x I had, and I was easily able to brush the 4930k aside and keep up with a 5820k. However, I needed to go 4.9ghz to do that and it ended up popping my board.

I would do it personally speaking, however, I would go 1700 and B350 Strix for maximum bargainage.

Geekbench licks Intel's backside. You can safely ignore that.

Just get a rig for testing. Ryzen R7 1700X, 16GB DDR4 2400, ASUS Croshair VI Hero with Corsair H115i. Rendering (blender) seems to be greatly improved by 8C-16T, as for gaming seems to be just the same or slightly better performance.

I recently did research for my brother's build. He works in AutoCAD Revit. For AutoCAD specifically single thread performance is all that matters. You didn't mention budget but 7820X will give you bigger performance gain in all of those tasks. The price will also be bigger.
