To determine the performance of your computer you should test it.
At the present time there are test programs for testing hardware. The Bryce application is suitable for testing of CPU render time of a 3D scene.
The proposed test was done in 2004. For this test a scene with 7 mirror balls and three light sources of different intensity and color was built. The objects located over the textured water surface, where the borderless plane is covered with texture of soil under the slightly translucent layer. In the background over the water surface rises the textured terrain. Image size of 800x600 (72 dpi).
The main task of the test was to determine the rendering time of a scene for different computer configurations for different operating systems with different versions of DAZ Bryce. On those machines were temporarily halted all working process that do not participate in service of operating system and DAZ Bryce software.
Before the rendering process, you must set up the options as shown.
Then once you click on the big ball (Render) left side of the the interface, and wait when rendering is complete. The rendering is over when the system window with results is open.
The largest figure represents parameter that you want to evaluate the speed of CPU.
In fact, it is the rendering time of the scene, shown in minutes and seconds.
