Are Two Cores as Good as Four Cores?

Michael from CMPLive decided to do a special episode of “Real or Hoax” for our channels. He is a brave soul, and decided to take on the age-old question of whether or not two cores really are as good as four. In order to do this test properly, he made sure that the machines used were truly alike, apart from the cores themselves.

To run this test, Michael performed tests on four different popular games. He also did tests on several different types of software. You can see from the graph shown in the video, there’s a significant difference in the performance, but could easily be a bottleneck in the graphics. The difference is most definitely NOT double, though, as you might expect.

During a different test, Michael set his graphics to the highest possible settings. Low and behold, there was NO difference between two cores and four cores as far as performance. This is because his graphics card experienced a bottleneck long before the CPU would have.

When testing playing Assassins’ Creed, you can see by the charts that both low and high graphics usage produced nearly the exact same results – no matter how many cores were being used.

Flight Simulator X has been long believed to be CPU intensive… again, though, there was no difference. How can this be so?

Overall, Michael proved that there truly is not much difference when you use four cores instead of two. The biggest difference was in rendering and processing videos… the quad-core machine definitely performed faster. In every other case, though, it didn’t matter how many cores were installed in the computer. When it came to the games, the graphics card mattered far more than the CPU itself.

Thanks, Michael, for producing a fantastic video for us.

Processor Speed Vs CPU Cores

If you had to choose between a 2.2 hz quad-core or a 2.5ghz dual-core one, how do you know which is right? In my mind, you’re better off with as many cores as you can possibly get. Even if software is not optimized for maximum cores at this point, it certainly will be in the future.

If an app is designed with multiple cores in mind, you’ll be happier having more cores no matter what the processor speed is. It depends on opimizational code, honestly. Check your benchmarks, and see how the two processors compare.

Dollar for dollar, though, I’d go for more cores rather than the raw speed of the processors.
