Hello George,
That’s one mighty PC you’ve built there. It’s beyond me to extrapolate from your benchmark results to my world, i.e. working with a different image count @ 42 MP and very different system resources, so I’m interested more in your general response to some questions geared at evaluating things like dual socket CPU and performance of the Titans.
Ivan (thanks again, Ivan, for putting this conversation and utility on its feet, see how we benefit?) suggested early on that he’d take fewer faster cores than more slower. I see you went with dual 2.7 GHz CPUs, 18 cores each. Maybe, you had other considerations in your choice, e.g. running two CPUs cooler, needs of other apps, but did you run any comparisons with single CPU and/or with faster CPU to inform that perspective?
It’s been my impression that a Tesla verges into the case of diminishing returns relative to a 1080 Ti, the cost/value being hard to justify. Time is money, so I assume your projects yet justify your pulling out a sledge hammer - correction - two sledge hammers. What kind of memory pressure are you seeing in Resource Monitor on the first GPU, the second?
How about RAM? At a fraction of your whopping 256 GB I rarely see memory pressure in RC, really only after reconstruction and texturing, where GPU memory doesn’t support Sweet display quality. I suppose that’s at least one area your Teslas rock.
I’m still relatively new to Windows PCs. I came up with Macs mid-80s, do miss the construction quality, and in the case of the Mac Pro “trashcan” I’ve yet to see a slicker approach to thermal regulation. I’m currently running a i7-7820X in an ITX case, the smallest form factor supporting the 980 Ti short of a laptop (didn’t want the heat). This ITX is now gasping its last breath, thanks to a Delta agent who performed an atomic body slam when dropping my well-padded storm case onto the belt from chest height. (I later found the GPU loose inside the case, rear metal mounting plate peeled back with mounting screws ripped clean out! So many loose connections, had to rebuild from scratch 3 times to finally get video up and operating system to load.) I’m now getting BSODs, believe a weakness on the motherboard has now broadened into a tiny bridging gap hiding somewhere. So, I’m now going with a Boxx laptop I can take carry on, use in field to validate a day’s capture and for demos, but for desktop I’m pulling out my tower ready for parts. I’d like to repurpose my i7-7820X and possibly bring in a second one. Thanks for your thoughts.
