I have a 10 year old 2008 Mac Pro 8 core 2.8Ghz with a Geforce GTX 970 running Zwift at the moment. It does OK in Watopia and runs 4K settings and I get from 30fps up to about 80fps out in the country side, but in the centre of Insbruk with lots of people around and all the buildings etc it drops to around 16 or 17 at times, but picks up in other places to much better frame rates.
Am thinking of building a new pc to run Zwift and am wondering if I use something like a Ryzen 5 1600 or latest i3 4Ghz with the GTX 970 will it make much of a difference to frame rates? Am trying to keep the costs to a minimum.
I have been watching the cores used on the Mac Pro while Zwifting and it uses all 8 cores, but not to any great extent. I am aware that the graphics card does most of the work in Zwift, but wonder if I build a new system will it be much better than the old Mac Pro? Ram speed etc on the 10 year old computer and single core speed are very slow compared to modern systems, so how much difference will it make?
Is there any benefits from a 6 core Ryzen which has better multicore bennchmarks compared to a 4 core i3 with faster single core speed but slower multicore?
