Hardware / Re: Ryzen 9 9950X, Which RAM set-up will be the best for 3ds and Corona?
« on: 2025-06-27, 13:17:38 »
Howdy! Below are my 5 cents, all personal opinion of course :)
1. Do you think that Ryzen 9 9950X3DX will be any better than Ryzen 9 9950X for Corona?
I never owned an x3D Ryzen but my impression is that no, the x3D chips don't appear to be any faster for when it comes to rendering with Corona (and I'd say the same for V-Ray). My guess would be the cache is just not that important unless you don't have enough of it for normal operation. Even if it is faster I would expect it to be marginally faster whereas the price difference isn't marginal at all - at least not in the EU where the 9950x goes for about 550€ and the x3D for 710€.
2. What configuration of RAM you recommend ? I was thinking about 2x48GB to have 6000MT/s and CL30. Im not planning to do OC as long equipment will be on warranty, but here i don't know i I should choose faster over capacity. So : DO you think is better to have 2x48GB with minimum CL or it is better to go with max RAM capacity and go 4x48GB to have 192GB but slower the bandwith for 4 Modules instead of 2?
People might disagree with me here but honestly I'd go with the middle of the route approach. Have decent speed, decent latency and just plop in as much of the RAM you need and if possible make sure it is on the QVL list of your motherboard maker.
More RAM does not equal faster rendering unless you're running out of RAM (literally, meaning your scenes needs 80GB but you only have 64GB).
So if your scenes need 128GB then you'll probably need to do whatever gets you to 128GB. Personally, even though its been years since I built a non Threadripper / Epyc / Xeon system, I'd probably be conservative with speeds and latency for when it comes to high RAM amounts and 4x sticks. In the past 4x sticks were typically possible with lower RAM speeds.
Anecdotally, I tried switching between 3600mhz and 2667mhz (DDR4) on my older 3970x and I don't recall there being a noticeable difference in rendering speed.
Of course though, for non rendering tasks, you would want some sort of sensible speed - You probably don't need 8400 MT/s but you also probably shouldn't go below 4800 MT/s. That'd be my goal anyway.
And try sticking to the QVL list if possible. That is typically the least headachey way I guess.
Hope the above helps :)
