I have my new desktop PC and so some results to share. However I did not buy the water cooled i7-7820X beast that I was pondering. When it came to it, this was a much more expensive solution that I was finding hard to justify.

20MP, 20MB, 3200 ISO image, typical corrections including Prime NR used for the comparison. Export to 100% jpg at 350dpi.

My old  i7-860 manages this in 77 seconds.

My new i7-8700 just 21 seconds.

The base clock of the 8700 is 3.2 Ghz. During a Prime export, clock speed is over 4Ghz, maybe hitting 4.14GHz. So not the 4.7GHz peak turbo clock speed it is capable of, but not running at base either.

The i7-8700 (6 core) only peaking at around 89% utilisation during a Prime export.

Thanks for taking the time to test and share this. The above tests are with or without Prime NR please?

Well, I completely blew that benchmark - I used images I had not processed and did not select PRIME NR....(I always use PRIME for pics I finalize)....    :-[  :-[

So NEW numbers with PRIME (JPEG 100%) are:

8 cores/16 threads
-   31.5 sec First Image
-   24.1 sec Subsequent Images
-   53% Processor Usage

8 cores/8 threads
-   31.5 sec First Image
-   24.0 sec Subsequent Images
-   100% Processor Usage

6 cores/12 threads
-   36.6 sec First Image
-   29.7 sec Subsequent Images
-   70% Processor Usage

6 cores/6 threads
-   41.4 sec First Image
-   31.1 sec Subsequent Images
-   100% Processor Usage

4 cores/8 threads
-   48.5 sec First Image
-   39.3 sec Subsequent Images
-   100% Processor Usage

4 cores/4 threads
-   49.6 sec First Image
-   42 sec Subsequent Images
-   100% Processor Usage

3 cores/6 threads
-   62.8 sec First Image
-   50.6 sec Subsequent Images
-   100% Processor Usage

DxO maxes out on processing at 8 threads/image and 8 cores.  There is no difference between 8 cores/8 threads and 8 cores/16 threads.

Do you have any idea on if the recent patches for spectre and meltdown have a large impact on this?
