Intel Core i7-7800X for davinci resolve

PostTue Sep 18, 2018 5:25 am

I am going to buy a new computer to work with davinci resolve. I am looking for a processor. Is the choice of Intel Core i7-7800X good? It has 6 cores and 12 threads. In the future I want to replace it with Intel Core i9-7900X (10c/20t) or even Intel Core i9-7960X (16c/32t).
How will the skylake x develop?

Or how about Threadripper 1900X 8c/16t?

Hi Szczemp.

I will try to answer both of your posts. The small skylake x cpu's have to few PCIe lanes for Resolve.
And Intel will at the end of the year launch a 28 core and 56 threads desktop CPU. We don't know a lot about it, but it will use a LGA 3647 socket.
I will some time expect new HEDT Cpu's to. But which will use the LGA 2211 sockets and which the LGA 3647 socket we don't know.

AMD have reduced the price of last year 12 cores 24 threads 1920X Cpu to around the half. That will I suggest for a entry level CPU.

I have made a small guide for a recommended build. Here is a copy and paste of it to you:

'Carsten's hardware guide for DaVinchi Resolve. Version from 20. September 2018.

In Resolve the CPU is used to run the app, disk I/O and compression and decompression of codecs.
Resolve does all its image processing in the GPU on the graphics card. More CUDA/OpenCL Cores are better.

nVidea have just introduced the new nVidea RTX 2080/Ti Graphics Card series. For 4K choose one with 8-11 GB of vRAM. And more CUDA cores is better.
Recently there have been some price drops on the previous generations GTX 1080 and GTX 1080 Ti and as long that the new RTX 2080 8 GB cost $100-$150 more than the old 1080 Ti 11 GB will I
recommend a 1080 Ti 11 GB purchases in the $650-$700 class. There is a maximum of one graphics card in the free version of Resolve. If you use Noise Reduction etc. then you probably will need 2 GPUs with 11 GB vRam each and the paid Studie version of Resolve.

In the DaVinci Resolve 15 configuration guide is one of the suggestion on page 18 the AMD Ryzen Threadripper CPU.

https://documents.blackmagicdesign.com/ ... _Guide.pdf

All AMD CPU's loves fast memory, and on page 36 under GIGABYTE Motherboard:

16GB (4x4GB RAM) DDR4-3200 SDRAM minimum
64GB or 128GB or more recommend for FUSION

On August 13th did AMD launch AMD Threadripper next generation with a little cheaper CPU's. For 4K work look at the new 16 cores 32 threads 2950X that get much better reviews than expected.

When I try to check prices don't I yet see any big price drops on the previous 16 core 32 threads Threadripper 1950X CPU's. So far for 16 core 32 threads CPU will I recommend the new 2950X. While I currently see some large price drops on the 12 core 24 threads 1920X CPU's.

Both the old and new Threadrippers CPU use a TR4 socket and a X399 motherboards. Suggest you to buy one with nice reviews. If you later want to upgrade to a faster CPU will I suggest you to buy a Asus motherboard, as they can be upgraded to a TDP of 250 Watt by buying the X399 cooling enhancement kit coming to September.
For CPU's with more than 20 cores will I look for a motherboard with a 16+3 VRM circuit.

Look here for a Free NVMe RAID upgrade for AMD X399 chipset:

https://community.amd.com/community/gam ... 99-chipset


All motherboard have a QVL List you can find on the manufactures homepage. Here you can see what DDR4-Ram they have tested in that particular motherboard. The Configuration Guide recommend to use minimum DDR4-3200.

The cheapest recommended RAM is many times the G.Skill Flare X DDR4. The Flare X series is made special for AMD CPU's

The Threadripper CPU's have a 4 channel memory design. You will get the fastest system by using 4 DIMM's only, and leave the last 4 sockets empty.

Do you still have some questens you are free to ask.'

Regards Carsten.

What codecs are you shooting on and at what resolution?
What are your goals, speedwise, output resolution, VFX, color, etc...

For a desktop, first look a AMD Ryzen7 or Threadripper (cheaper, more PCIe-lanes, less vulnerable for hardware leaks like, Meltdown, spectre, foreshadow, etc...).

Now I am shooting in h264, sometimes prores, both fhd and 4k. But I am thinking about buying a pocket 4k, and want to use the potential of the camera. Not now, maybe next year or later.
