Thank you for your reply. Your arguments support my findings 100%.
As for desktop vs laptop, I would argue that a (reasonably prized) laptop will not perform anywhere near as good as a desktop. In addition, in my experience a self built desktop will always be more affordable than anything prebuilt.
I spent most of today researching CPU’s and GPU’s and I have narrowed it down to these possible setups. I took into account the hardware requirements for both SU and Vray and my workflow.
From what I have learned, SU benefits most from a CPU with high clock speeds. The way I see it, the motherboard, the RAM and the storage can influence the data throughput so these matter as well. Though SU itself may not benefit from having multiple cores, the GPU will run smoother for it when it receives its data timely.
I expect that my workflow ratio SU/Vray will be somewhere around 70/30. With that in mind, I am inclined to lean toward a fast CPU and compensate the spending for a ‘beefier’ CPU with a simpler GPU – if only to start out. The GPU can be exchanged easily over time as budget allows. Should push come to shove, I can always rely on the Chaos cloud render when needed.
Intel i7 or Intel i9
Based on various accounts and benchmarks, it seems to me that the Intel 13th gen series outperforms comparable Ryzen CPU’s. I am leaning toward either the Intel i7 13700 or the i7 13900. Given that my current machine is a 2017 MacBook Pro 3.1GHz 4-core i7, I think I should go for the i9 since I don’t run SU all that smoothly on this laptop.
DDR4 or DDR5
I have read various accounts that DDR5 ram is not yet worth the extra spending but since it is a lot faster than DDR4 and given the single threadedness of SU I would expect a DDR5 setup to outperform DDR4 for SU – and be more future proof. 2x32 MB to start…
M.2 NVMe SSD
The faster data can be accessed and processed, the better. Right? So I am likely going for an NVMe SSD. 1TB to start off, but a friend of mine pointed out that a RAID setup would even be faster. However, given a read/write speed of 7300/6000 MB/s (for the one I chose) I doubt that it would be worth the extra spending of around € 150.
GeForce RTX ???
Now, the GPU. That one gives me the biggest headache. Not taking into account the cost of a GPU, the difference in cost between an i7 DDR4 (± € 1400) and an i9 DDR5 (± € 1750) setup is around € 350. i7 DDR5 and i9 DDR4 are comparable in cost and sit neatly in between (± € 1500 - € 1600).
I have looked at the 3070 (ti) and 3080 (ti). Anything above that (either the 3090 or the newer 40## series) is really above what I want to spend.
Currently, I am still torn between choosing the i9 DDR5 with a 3070 ti card at 6144 CUDA cores/8GB (± € 2400), or the i7 DDR 5 with a 3080 ti at 10240 CUDA Cores/12GB (± € 2500). Or just go for the i9 with a 3080 ti at ± € 2900
What are your thoughts?
I am really hoping that you guys can give your 2 cts on this, which setup would you advice?
Thanks for reading this all the way to the end!
