Mandel FPU test

The Mandel FPU benchmark measures double precision (also known as 64-bit) floating-point performance through the computation of several frames of the popular "Mandelbrot" fractal. The code behind this benchmark method is written in Assembly, and it is extremely optimized for every popular AMD and Intel processor core variant by utilizing the appropriate x86 or SSE2 instruction set extension.

If you come from the Commodore 64 / Amiga era like me (Peek & Poke Commands FTW dude!), you can probably remember rendering Mandelbrot graphics, a mathematical formula that much like a paradox, never ends and thus is repetitive. Back in the 1990s it took me a full day to complete one Mandelbrot image. Amazing where we are right now as the same set of calculations can be done in a split second & even real-time.

The FPU Mandel test again is HyperThreaded, multi-processor (SMP) and multi-core aware. The Phenom II X6 1100T and FX 8150 are the fastest AMD processors currently, but are outmatched by Intel's latest processors. The updated Mandel test now embeds AVX support and that shows alright. The test does not allow AVX to be disabled.

ZLib Compression

This integer benchmark measures combined CPU and memory subsystem performance through the public ZLib compression library Version 1.2.2.

The ZLIB compression test was recently overhauled as well, hence we had to startup from scratch here again as well. This integer benchmark measures combined CPU and memory subsystem performance through the public ZLib compression library. CPU ZLib test uses basic x86 instructions, no AVX, and it is HyperThreading, multi-processor (SMP) and multi-core (CMP) aware.
