HOW DOES CINEBENCH WORK?
This will test every byte of RAM your Mac has access to once. If you want to continue testing your RAM indefinitely use the following command:. You will notice that memtest will only test a small subset of free memory available to you. To test it all you will have to boot into single user mode.
Once it has finished booting you will see a black screen with white text. Type memtest all 2 to test every bit of available RAM. Restart to get back to norma. The final core component of your Mac is the hard disk drive. The crucial component that holds all of your data. Over time these degrade and slow down. When you load the app select the disk drive you want to test. Then select the size of file you want to write.

I recommend the largest of 5GB. Hit the start button and it will test the read and write performance your your disk drive.

It will keep doing this until you tell it to stop. Note, if you get an error saying it cannot write to the disk, select your user folder or something similar. Sometimes selecting the root of a drive causes an unwritable error message. You can save the result of the disk speed for later use. My SSD drive has only slowed by a couple of tenths of a megabyte over the last year. All of these separate tests are useful, as well as free. However, if you want some more concrete numbers and a more repeatable test I recommend you download and buy Geekbench from the App Store.
At the end it gives you a score which you can save and compare later. I recommend you close down every app since the final score can be heavily influenced by what apps are running.
Stress Test a Mac by Maxing Out CPU
There are many ways to stress test your Mac. Most of the methods are free and give you good results. It is always interesting to see how your Mac shapes up over time. Stress testing can also be a good insight into any possible failures. Especially with testing using memtest, if there is a fault on your RAM chips, it will find it.

They open and close so beautifully. If you want a quick way to re-dial on your iPhone. This test scene contains approximately 2, objects which in turn contain more than , polygons in total, and uses sharp and blurred reflections, area lights, shadows, procedural shaders, antialiasing, and much more.
The result is displayed in points pts. The higher the number, the faster your processor. This procedure uses a complex 3D scene depicting a car chase created by renderbaron which measures the performance of your graphics card in OpenGL mode. The performance depends on various factors, such as the GPU processor on your hardware, on the drivers used.
The graphics card has to display a huge amount of geometry nearly 1 million polygons and textures, as well as a variety of effects, such as environments, bump maps, transparency, lighting and more to evaluate the performance across different disciplines and give a good average overview of the capabilities of your graphics hardware. The result is measured in frames per second fps. The higher the number, the faster your graphics card is. System administrators can use CINEBENCH to help make purchase decisions, journalists can use the results in reviewing hardware, hardware manufacturers may utilize the feedback in optimizing their latest products.
Any computer owner can evaluate his or her individual system. Supported Processors: On systems lacking sufficient RAM to load the test scene, a warning will be displayed and the CPU benchmark will not be executed. A small difference is tolerable displayed in green pixels , as it results from slightly different shading, etc. This may indicate that transparencies, shadows or other display properties are not properly supported.

In some cases the test will be executed anyway, but no result will be displayed as it cannot be accurately compared with others. In extreme cases, the OpenGL benchmark will not be performed. The reference match score indicates the ability of the graphics card to properly display these features.
Any card that produces a reference match at all can be used with Cinema 4D, but a low score indicates that the display will be inaccurate and less pleasing. Keep in mind that driver updates can also affect the reference match score. In most cases, you should always ensure the most recent stable driver version is installed on your system. On Windows systems, you can download drivers from the system or graphics card manufacturer and install them manually.
On Mac OS X, make sure any pending software updates have been applied. Significant effort has been directed towards the design of the OpenGL test scene to make the task of benchmarking a bit more exciting. The car chase used in this test is designed for a PAL-standard of 25 fps. To prevent the scene being displayed much too slowly on old graphics cards or much too fast on the latest hardware, CINEBENCH estimates the graphics card performance so the scene will maintain a consistent duration approximately 30 seconds.
Faster graphics cards will display the scene much smoother than slower ones. If a graphics card can display a higher frame count than the original scene speed, subframes will be displayed and properly measured. This doesn't fully reflect the polygon count processed by the graphics card, which is between , and 1 million polygons.
The difference results from several factors. Graphics cards are incapable of drawing quadrangles, so these must be converted to triangles. This roughly doubles the polygon count. Furthermore, multiple materials one on each side of the triangle or transparencies require the scene to be drawn twice. Other factors, including using multiple materials and transparencies in combination require a triangle to be drawn multiple times.
Depending on the camera angle, the graphics card may be displaying several times the number of polygons reflected by the basic scene information. Unfortunately the system contribution cannot be specifically measured. The same graphics card in a faster computer will typically give better results than in a slower system. The overall performance depends on various factors including processor, memory bus and chipset.
All geometry, shaders and textures are stored on the graphics card prior to measurement, and no code is loaded during the measurement process. This minimizes the system influence, but unfortunately cannot eliminate it entirely. Graphics card drivers can greatly affect the benchmarking performance. On Macintosh systems, drivers are usually installed automatically with the OS and cannot be modified.
