I understand that higher clock speed is better for reconstruction while more core suits AT
I am looking at either the i7 8086 (6 cores 5ghz) or the i9 9700x (10 cores, 4.3ghz)Despite a lower clock speed will the increased core count of the i9 still make it faster at reconstruction?
Will be paired with either 64gb ram (i7) or 128gb ram (i9) with 2 x 1080ti
Any feedback would be appreciated. Thanks.
How did you go? Another thing worth mentioning - run some workloads and watch performance monitor/task manager to get a bit of a feel for what is going through for your jobs.
Task Manager for Windows 10 usually has GPU - or grab MSI Afterburner (free) to see the peaks/troughs .. GPU work .. single vs multi threaded aspects of what is going on.
One thing I have noticed is that tile size has a pretty big impact on GPU "blocks" .. so bigger tiles seem more efficient in that that do large chunks of GPU work at a time. Small times - say 10 mins to process might only have 1 min of GPU work.
You could probably try and time it - and from there come up with some metrics on cores vs clock speed vs GPU vs dollars to come up with the most bang for your buck.
We ended up with the i9 configuration.
We considered having 2 workstations but doubling licensing costs plus managing an additional machine wasn't favourable.As you mentioned though, looking at the second 1080 in task manager it is rarely being used.
For reconstruction we're getting about 25-30 gigapixels per day.
