Choosing the right CPU for 3D tasks

Hi,

 

I´ve been doing my research but the more I look into it, the more I feel overwhelmed by the amount if information out there.

 

Primarely, I´m looking into buying myself a complete new workstation for professional 3D related tasks with multiple applications (Maya, Photoshop, Unreal Engine, rendering etc.) usually running at the same time.

My currently chosen seller offers primarely intel and I boiled it down to choosing between:

  • Intel Core i7-6850K 6x 3.60 GHz
  • Intel Core i7-7700K 4x 4.20GHz

According to what I´ve found out so far is that for gaming, the 7700K with it´s higher clock speed would be better but as my professional applications are more important to that, the 6850K with its extra 2 cores would be the better choice although coming with a smaler clock speed.

 

Which one should I go for? Is there a better choice? 

 

I´m very thankful for any input!

Why not Amd threadripper?

i don't know much about rendering, or 3d apps, never use them. 

 

i've heard they like cpu cores, especially if you are multitasking. 

also, a 6850K is overclockable, hence the "K". you could probably OC it to the speed of the 7700K. however, the 6850 is a 6th gen chip. this means it's approx 8-10% slower than a 7700 at the same clock speed with the same amount of cores, if that makes sense.

You can't really notice speed difference if it's under 10%. unless you benchmark it

Otherwise my daily rig is some oem pcchips motherboard with intel 486-dx2 in it overclocked to 100mhz and watercooled with astonishing 24MB RAM and superb S3 Virge DX graphics with 4MB of VRAM for best performance in heavy 3D apps and games and with 850mb WD Caviar 4200RPM HDD for maximum storage space and speed.

Forget about gaming and focusing on the more professional tasks, I would look into how your applications handle multi-core workloads. Also keep in mind that the 6850k is based on the broadwell-e architecture whereas the 7700k is based off the kabby lake architecture with more Instructions Per Clock (IPC). I would probably say the 7700k because the better efficiency and IPC and the lga1151 socket will be relevant longer.

 

Keep in mind the 6850k does not have an integrated gpu so a GPU would be MANDITORY.

An 8700k would be alright. However a Xeon with its higher core count would be much better.

You will be able to tell when rendering 3d cad files and other 3d work.

Thanks for the input! Reading trough everything right now.

 

Just realised my seller also offers AMD CPUs so one of the new Ryzens like the "AMD Ryzen 7 1800X 8x 3.60GHz 95W" would also be possible to put into the configuration if that helps the discussion.

You see, Maya and PS favour single core performance while rendering software generally prefer a ton of cores. Either way dont get Kaby Lake (or Skylake) new. They are so expensive despite not being upgradable to future CPUs anymore that it's more like a ripoff.

 

6800k (just 6850k with some PCIe lanes removed, doesn't matter to you) or Ryzen 7 1700 will be my pick. One has higher single core performance after overclocking but the other platform will receive new CPUs in the future.

 

Neither X99 or Ryzen have integrated graphics, but for a workstation graphics card is mandatory anyway.

It's already irrelevant since 8th gen doesn't support 6th and 7th gen motherboards.

AMD RYZEN would be the more cost effective choice, however with amd you will want to ensure that the applications in your workflow will adequately utilize the multi-core performance. The 1700x (8 core 3.4GHz) would be the ryzen chip in the same price range.

Would it make sense to wait for 8th generation?

if you can get your hands on a Ryzen 7 it's the best price for an 8 core/16 thread CPU and will serve you better.

It does, unless you cant wait that long. The ideal time will be the first quarter of next year. That's the US time though, maybe you have to wait even longer.

 

EDIT: 8th gen is already out but is as expensive as [profanity] due to low supply.

render times maybe? 10% on 10 minutes is still a minute.

yes, but the OP was concerned about clock speed for gaming.

In that case the lower overclocking headroom of X99 should be mentioned first

I have the 1700 (8cores 16 threads 4ghz) and in my workflow it is around twice as fast as 7700. If you have the budget go with a threadripper 1920x, because it has four more cores (12 cores 24 threads)
