processors

So is there a bennifit to going to a xenon processor over a i7 or vise versa. and is it worth having multiple processors onboard

The answer, as you might have suspected as with all things Touch, is that it depends.

Touch is largely single threaded. Most CHOPs, SOPs, and DATs, run on the main thread. The movie file in TOP, however, is multi-threaded which will spread out video decoding across cores. If you’re lots of video playing, swapping, and the like then the answer is yes - multiple cores are better for performance.

If, on the other hand, you’re largely focused on live rendering then having lots of extra cores doesn’t give you a significant performance boost. Instead, it would be better to have fewer cores that are faster - since this will benefit CHOP, SOP, and DAT operations.

TOP operations are mostly GLSL warpped in a nice UI element. This both means that they’re fast, and most importantly that they happen on the GPU. Operations on the Geo COMP also happen on the GPU.

Chances are, you want to do a bit of both. In which case, a multi core machine is better - but it’s important to know how the load is distributed across processes in your project.

Is there a way to see how the project is running and how many threads each op is eating up

Some answers are in the links below. Performance analysis is hard. I still regularly struggle with understanding what’s costing me cycles and how to address the problem.

I almost always opt for faster and fewer cores. For most workloads you get more bang for buck, and if you’re using HAP codec the CPU drain isn’t incredibly large on movie files.

A quick search on that processor reveals it is a very budget processor, unable to keep up with i7 CPUs from many years ago. So I would say No, not recommended.

In most situations still, lower cores with faster clock speeds are preferred (4-core 4ghz > 8-core 2.3ghz), which makes the i7 gaming chips usually the ones we go with UNLESS we’re doing multi-gpu setups in a single machine then we opt for Xeons.

I’m putting together a touring PC for projection mapping purposes, (x4 1080 projectors + x1 monitor). Using CamSchnappr sparingly, with a lot of HAP and some H.264 content, with minimal live rendering. I’ve already ordered a Quadro P5000 (should be able to handle all my outputs if I go 4k out and split it), but am trying to decide between a quad core i7 7740x (4.3GHz) and an 8 core i7 7820x (3.6GHz). What should I be considering to make the best choice here? Will I see a noticeable difference in these options, and under what conditions?

Any recommendations would be welcome.

Thank you in advance!
