I'm looking for a tool which can execute a number of different CPU speed tests. I just want to compare how much faster my computer's CPU is from another.

I also want to test "just one core" because I want to know how much faster I can execute a task which can not be paralleled.

I also want the tool to be able to test a "2 physical processors" configuration.

An example of a test could be, "calculate 100 000 numbers of pi," etc.

I would expect the tool is free, doesn't require an install, and works on both Windows 7 and Windows Server 2008 R2.

I'm looking for something simple. It could be even command-line. I may even write a program myself which calculates "pi". I don't need a "fancy" interface, xml reports, auto-update, built-in comparision to other processors or anything else. Just a tool which produce results.

Great story, not much of a question. :) What have you tried already? Where are you getting stuck? Unfortunately, just asking for a list of tools is a good way to get your question closed. –  Ƭᴇcʜιᴇ007 Jun 19 '12 at 12:16
@techie007 i didn't tried anything just looking for something that feets my needs –  javapowered Jun 19 '12 at 13:07
Would prime95 do what you want? –  HaydnWVN Jun 20 '12 at 15:06
@HaydnWVN probably. I've used SuperPi but it tests only one core. –  javapowered Jun 20 '12 at 15:08

It is not recommended to run Benchmark test without installing the software, also the benchmark should run on native architecture for best results. You can try these programs.
I have not tried any of these software.

  1. Portable BruteBenchmark
  2. CrystalMark
  3. PC-Wizard

These software are portable, but I dont recommend using Portable Benchmark for Comprehensive and good results.

Others could be like..

Some more can be found here (Maybe not so good)

Use these on your own risk.
