HI all

I've seen a few computer specs mentioned for DAZ Forum but can't remember seeing AMD only.  I dont have anyting against Intel as such only that i feel they are overpriced and out of principle i do not buy there products. So anyone here who uses AMD Ryzen or similar to below ?

Mobo:

ASUS ROG STRIX B350-F GAMING AMD Ryzen AM4 DDR4 HDMI DisplayPort M.2 USB 3.1 ATX B350 Motherboard

ASUS ROG STRIX B350-F GAMING AMD Ryzen AM4 DDR4 HDMI DisplayPort M.2 USB 3.1 ATX B350 Motherboard

CPU:

AMD Ryzen 5 2600 Processor with Wraith Stealth Cooler - YD2600BBAFBOX

AMD Ryzen 5 2600 Processor with Wraith Stealth Cooler - YD2600BBAFBOX

Memory:

Corsair Vengeance LPX 16GB (2x8GB) DDR4 DRAM 3000MHz C15 Desktop Memory Kit - Black (CMK16GX4M2B3000C15)

For GPU im getting a single GTX1080Ti 11GB and not going to wait for an over expensive RTX2080 series or such. WIth DAZ4.11 my renders are  now pretty fast and look very good so a faster / higher end pc to what i have now can only help.

As I have not bought any new pc parts in last few years I am not to clued up with regards to latest AMD tech.

Thank you

    Depends on what youre using your PC for. If mostly Iray, then the 1080ti is great, and what CPU you use is somewhat irrelevant. I have a Ryzen 7 1700 with 8 cores and most of the time it sits there unused. Fewer and fewer software packages utilize the CPU nowadays. Check your software to see what it needs

    Hi its for DAZ and the CPU currently is always used around 34% so it is used along with ram and VRAM from GPU.. but i think ill get that. THx

    I use a Thread Ripper 1950X on an AORUS Gaming 7. It is better than twice as fast as my Athlon X6 for compiling code on Linux when it can use all 32 threads, but to be honest, the UI seems sluggish in Daz Studio. I don't think Daz Studio is multi-threaded very aggressively. This makes me think that maybe Intel is better for Daz, as they still have a per-core performance edge.

    But also consider that, as you already observed (34%), much of that is not CPU bound, but I/O bound, so a good use of your money would be a PCIe based SSD. Daz probably jumps all around your filesystem to read objects, something spinning platter hard drives are terrible at, in terms of latency.

    As for rendering, I initially has a GeForce 950 and man, was that was painful. I upgraded to a 1080ti and rendering in Iray got three times faster. I didn't time dForce simulations. I added another 1080ti and surprisingly, the render speed DOUBLED AGAIN. I understand that raytracing is one of those "embarrassingly parallelizable" problems, but things hardly ever scale linearly. Well, this time it did! But when I render an image say 4 times the size in order to scale it back down to remove firelies, you can really feel the heat radiating from the case. The system remained stable, but that can't be good for long-term reliability.

    All in all, the GPU and SSD upgrade had a much, much bigger impact than the CPU did.
