Please help me understand this benchmarking

post #1 of 6
Thread Starter 
Hello all. I was just curious and did some google searching of all high end CPU in 2010. I came across this chart:

http://www.cpubenchmark.net/high_end_cpus.html

I don't understand what it's calculating though. Can anyone assist with this? Do you think this is a valid site for benchmark results?

each cpu benchmark consists of many tests. Different benchmark softwares do it differently. The one you selected (passmark) uses various methods to find out the efficiency of the cpu and then calculates an average value by some complex equation.
The test run on the cpu usually consists of memory bandwidth test, video processing test (using cpu), compression speed test using zip or rar dlls, solving complex mathematical euations (actually the time taken to solve them matters, faster cpus do it faster) etc.
And yes, that site is trusted by many. It kinda hurts to see our AMD getting its ass kicked by I7 everytime, doesnt it.

Basically the site has gathered the results of benchmarks tested with each CPU and Rated them based on thier score.

Yes indeed....it does. I am not really partial to any particular brand, but in the past I've been known to go with AMD because it works and it's less pricey. When I finally hit the 6 figure salary then I might not care about the price of processors. I game, do server stuff, and all that other stuff just fine through AMD products. Yet and still Intel fanbois tend to look down on me. LOL!

It's a synthetic benchmark that uses a blend of different tests.

It uses the PassMark "Performance Test" suite to rate the CPU's. As explained here:
http://www.passmark.com/products/pt.htm

Standard test suites

* CPU tests Mathematical operations, compression, encryption, SSE, 3DNow! instructions and more
* 2D graphics tests Drawing lines, bitmaps, fonts, text, and GUI elements
* 3D graphics tests Simple to complex DirectX 3D graphics and animations
* Disk tests Reading, writing and seeking within disk files
* Memory tests Allocating and accessing memory speed and efficiency
* CD / DVD test Test the speed of your CD or DVD drive

So it tests those then assigns a score based on the results. So if you're looking at CPU benchmarks it will tell you the score of just the tests that relate to the CPU but if you're looking at a total system score it will give you a score based on the entire system. I'm not sure if that makes sense to you but hopefully it does.

ie. If I wanted to know the CPU score for my system so it will return the results of the CPU tests. Now if I wanted to know the score for the entire system it would return the score for the entire system.

I have not used this software to benchmark my machine so I don't know how it works but the explanation above is just a general high level explanation of how benchmarking software works.

NB: The "score" is an arbitrary number and has no meaning in real life (other than to "rank" different components) you can't take this score and compare it to another benchmark suite that scores another system since it might use a different algorithm and scores might be totally different numbers (ie. System A scores 100 in Benchmark Suite1, and System B scores 10000 in Benchmark Suite2. System B may be a comparable system component wise but the benchmark suite has a totally different scoring system and assigns differing amounts of "points" to the same components). It's generated by some algorithm that rates performance of different things in the system.

@Amor, Ok, I'm glad you cleared the SCORE thing up. I wasn't sure what the numbers actually corresponded to. Because I see the SCORE at the top was somewhere in teh 10,000 range while my rinky dink CPU was somewhere at 4,000. Way to to blow my high. LOL!
