END OF AN ERA, FRACTALFORUMS.COM IS CONTINUED ON FRACTALFORUMS.ORG

Depends on what you can afford.

am attempt of a serious answer: it depends on what you want to do...
the deep zoomers here want high integer power, the cpu 3d renderers (and most other fractal renderers) need high float performance and open cl or cuda engines need a fast graphics device.

A no more helpful, but more serious answer:

Unfortunately, the various fractal generator programs out there have very different needs. This means that for some programs, AMD processors will offer the most value. Many other programs run much better on Intel processors. And finally there is a new crop of software that uses the GPU to do computation; these will like beefy graphics cards.

If you are undecided, the safest bet is probably a midrange quad core from Intel (no Hyperthreading required) with built-in "better than nothing" graphics. If it turns out you like using programs that run on the GPU, you can later add a graphics card in entry level "enthusiast" range (ideally a discounted model from last year's generation).

Do not buy the absolute high end. The price premium is generally not worth the performance increase. The graphics card doesn't really need to be compatible with the latest buzzwords, as long as it is a relatively recent model. The important capabilities (computational uses, double precision floating point throughput) of GPUs are usually not advertized, so you best ask again more specifically before you spend a whole lot of money. Both AMD and NVidia offer very similar capabilities in that regard; it depends on the specific models.

An AMD processor can be a good option if you already know that you want to do extremely deep zooms with multi precision arithmetic. For anything else, an Intel processor at a similar price point is probably more suitable.


In the unlikely case that you are a graphics designer who can live off of fractal animations, you can go crazy and buy a workstation with two or four multicore processors and two or more high end GPUs. You will probably overload even that machine eventually. :-) But mere hobbyists should not have any need to waste that kind of money.

Also having said all the above - to answer the original question, the minimum required to "actually enjoy" working with fractals and fractal art would be equivalent to a fast Commodore Amiga 68040 - e.g. say an old PC with a 486DX or Pentium 1 running at 200MHz or better

i.e. any system that can render the original Mandelbrot say at 100 max. iterations and bailout of say 32 at a resolution of 640*480 for (-2.5,-1.5) to (1.5,1.5) in under a minute using either fixed-point on CPU or on FPU using single-precision floats.
