Core i7 7700K or Core i7 6800K

DavidCivilEngineer · Mar 14, 2017

I am building a new computer for AutoCAD Civil 3D use mainly. I am looking at either using the 7700K (MSI Z270 SLI Plus Motherboard) or 6800K (MSI X99A Workstation Motherboard) 16GB Ram and NVIDIA Quadro M2000 video card. Which would be the better CPU for a workstation? No gaming at all.

Thanks
Dave

I would say look into ryzen for a workstation, it has very competitive pricing for more cores

Ryzen 1700 IMO would be the best for you, if you can only go intel then the 6800k

In short: Ryzen 7 1700.

For computer assisted drawings or simulations requiring heavy compute, more multithreading capability will be best suited.

The i7 7700K has the highest single threaded performance of any CPU in the market, this comes at a cost of having only 4C 8T, lacking great multicore performance. This CPU is excellent for getting high FPS in the latest AAA games, but is only mediocre for heavily multithreaded tasks.

The i7 6800K is expensive for its price as it requires to buy X99 boards. If you have to go Intel (recognized resale value etc) then choose i7 5820K with X79 as it offers better multicore performance then the 7700K. This CPU is good for both gaming and workstation tasks.

If you want to specialise this build as an exclusive workstation build, and dont plan on overclocking, a Ryzen 7 1700 with X370 board will be good. Ryzen 7 1700 has 8C 16T, offering great multicore performance yet maintaining a reasonable single core performance. This CPU will be the best for your needs, providing fastest simulations for your money.
However this may not provide highest gaming performance if you plan on gaming.

And the Ryzen 7 1700 comes with a bundled cooler and is the cheapest yet fastest in multithread.

If you go 1800X,

Couple of quick google searches, no real multi core support.

^ Which would suggest the 7700K. If OP doesn't plan to overclock a PC used for productivity, they could save some money with either a non-K CPU, or at least a non-Z chipset motherboard and a more basic cooler. I've always been reluctant to introduce possible instability into machines which I rely on for work.

Thank you for your post. I ended up building the system with the AMD Ryzen 7 1700 and the ASUS Prime X370 Pro motherboard, 32GB of Kingston 2666 RAM, Samsung 960 EVO 500 GB M.2 drive and NVIDIA Quadro P2000. System seems to be extremely fast but haven't loaded it down with a large Autocad drawing yet.

One question I did have, the memory is 2666Mhz, the motherboard is set to auto and it is only running at 2133 Mhz, I though about setting the spped on the motherboard, but at this time it is running fast and is stable. Do you think I would see any performance gain increasing the speed?

Thanks

I got the same issue on mine, by default memory will run at lower speeds than indicated on the RAM chip, just force it in BIOS to 2666 and you should be fine.

As a quick error correction, the I7 5820k Also uses X99 motherboards. The I7 4960X uses X79
