I’m struggling with some artworks I create which require a very long rendering time.
Beyond refactoring and code optimization I’d like to know what would be the best hardware I could use to speed things up?
Which renderer are you using?
You can see this previous thread about GPU and hardware accelerated rendering:
The only way to get good advice on this is to share an example of your application w/ code.
That said, technically, “what would be the best hardware I could use to speed things up” is pretty easy to answer: get a CPU with the highest available clock speed and the most L1/L2 cache; a motherboard with the fastest available Front Side Bus speed; a sizable amount of memory (>=16GB) with the fastest available memory clock frequency and lowest latency; a GPU with the fastest clock speed, the most GPU memory, and the highest memory bandwidth. Such a setup will be astronomically expensive and only give you marginal gains over something more middle-of-the-road. The moral of the story is this is not a particularly useful question.
