Historically Mandelbrot benchmark was my first online project and is derived from this experiment. It is close to my heart and that's the reason it has remained on the home page of my site. But telling the truth nowadays you have to be a really geeky power user to run Mandelbrot benchmark even in IE. So I suggest trying the javascript based benchmark and MandelX instead (both of which can be reached from the links below). Otherwise just look around the Windows and DOS software sections and find your favorite Falsosoft software.

Have fun.

MandelX 1.4.2


Mandelx is a very fast fractal generator that uses highly optimized assembly routines for calculations (multithreaded). Mandelx runs best on AMD processors. While the precision is enough MandelX uses the appropriate 32 bit SIMD floating point code path (SSE ,3Dnow!), then switches to 64 bit SSE2 and finally to FPU code. However you can switch between different code paths manually too. The FPU code uses 80 bit extended precision data so you can zoom deeper -without loss of speed- than with most other fractal generators. Integrated palette editor, palette animation, Record to AVI, and direct rendering to virtually unlimited picture sizes supported.


MandelX is portable and requires no installation.
