3D Rendering

This is not something I do personally, but I know a lot of people are into 3D rendering at home. To test 3D rendering performance, we make use of Maxon's CineBench program.

Based on Maxon's animation software, Cinema 4D, CineBench is a good real-world benchmark that makes comparing systems easier for those of us who aren't really familiar with creating 3D art. Cinema 4D was used to make such movies as Spiderman and Star Wars. Good enough for me!

Cinema 4D is heavily threaded - supporting up to 16 processors, and it scales incredibly well. Thus, it's a major benefit to anyone who is using this type of application to forget about everything else and built a system with as many CPU cores as they can afford. Aside from that, the E8500 shows an incredible performance advantage over the E6750, beating its performance-per-clock advantage by over 8% in itself.

Power Consumption

Because CineBench has seperate single- and multi-threaded modes, it makes for a good benchmark for power consumption. To test this, we ran each test with the system plugged into our Watts Up power meter in both single threaded and multi threaded modes. Average power consumption for the duration of the test is given, in watts:

It's clear to see that the shrink down to a 45nm die has allowed Intel to maintain their amazing power consumption advantage. Gone are the days of the "Preshott". Now we have a dual core AMD CPU that uses as much power as a quad core from Intel.

Using a bit of 5th-grade math, I was able to put the next graph together to put things into an even clearer perspective. Since we have a performance result from CineBench, and know the amount of average power used to obtain that result, we can find out how much power it took to achieve that result in the form of "Performance per Watt" (Higher is Better in this case):

This graph is able to show us that while the E8500 can't render as fast as the quad-core Q6600, it is much more economical in terms of power consumption.


Yeah I know, we already looked at the 'pure math' results on the first page of this review. But sometimes math calculation in itself works in practical PC usage. The most popular program for overclockers to show off their e-peen was SuperPi. Unfortunately though, that program is not multi-threaded. So to take its place, we have wPrime. wPrime actually has absolutely nothing to do with prime numbers - what it does is calculate the square root of really large numbers (upwards of 32 billion at this point). Total calculation time is given in seconds. If more than one core is detected, the test is split into several threads.

Aaaaand.. There you have it.
