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

CPU ZLib test uses only the basic x86 instructions, and it is HyperThreading, multi-processor (SMP) and multi-core (CMP) aware. A very good test to measure multi-core performance among platforms.

Again the Phenom processors take the lead. Look at the X4 9550 in overclocked state punch numbers btw. Pretty impressive.

Memory test

Lavalys Everest has an excellent tool to measure memory bandwidth. The differences are really close together, nearly neglectable, definitely not noticeable.

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 variants by utilizing the appropriate x86 or SSE2 instruction set extension.

Now if you come from the Commodore 64 / Amiga era like me, you can probably remember rendering Mandelbrot graphics, and it took a full day to complete an image. Amazing where we are right now as the same set of calculations can be done in seconds & even real-time.

the FPU Mandel test again is HyperThreaded, multi-processor (SMP) and multi-core aware. Here's where the Quad core processors always really kick in.
