This submenu provides the following information and tests for the graphics card:
- Information
Lists the graphics cards found (device class, manufacturer and device name), with memory size and clock speeds for supported cards; including monitor information via VESA-DDC (if supported). Information about the GPU computing capabilities using OpenCL (see below) is also displayed, if available. - Test image
Displays a test pattern with grids, colors, fine lines, and circles (not in text modes), similar to a television test pattern. The circles are only perfect circles if the pixels are perfectly square, i.e. the image is displayed in the correct aspect ratio. (Then press a key to continue.) - Basic colors
Displays the colors red, green, blue, cyan, magenta, yellow, white and black across the entire area. You can change the colors with the cursor keys, +, -, spacebar, backspace or directly with R,G,B,C,M,Y,K, or D for dark blue, as well as 0-8; F1 shows these keys. With F10 you go to the next selected mode, with Esc you end this test completely. - Grayscale
Shows 16 (or more) gradations from black to white (top half from left to right, bottom half the other way around) to assess the contrast/brightness ratio. (Then press a key to continue.) - Grid
Displays a simple grid image on the screen to assess the linearity of the display on the monitor. (Then press a key to continue.) - Colors
Shows colored bars, or gradients for modes with many colors. (Then press a key to continue.) - Visible Video Memory Test
Test the memory used by the graphics card in the current mode to display the user interface. This part of the memory is different from the global available memory used in the graphics memory test. - Graphics memory test
Tests accessible memory, if it is directly accessible, and runs memory tests on it. - Graphics memory test on GPU
This test, like the graphics memory test, tests the available graphics memory. However, the focus of this test is on dedicated graphics cards and requires an OpenCL-capable driver.
Webcam test
This allows you to assess the image from a webcam. If multiple webcams are connected, you can select the one you want. After starting the test, a window will appear on the screen with the current output of the camera. Webcams include, for example, tablet PCs with rear cameras for taking images.
Note:
The webcam test is an interactive test and requires your assessment for the test result.
Depending on the application of the device, you must determine whether the displayed image meets the desired requirements corresponds.
3D-Grafik-Benckmark (OpenGL)
This test runs an OpenGL benchmark with a selection of different scenes focusing on different aspects of acceleration. The achieved frames per second (images per second, FPS) provide a rough estimate Indication of the performance of the graphics card.
Note:
Linux uses its own drivers to access graphics cards. For certain manufacturers, device performance may vary under Windows and Linux. Intel and AMDoffer very good support. Unfortunately, Nvidia does not currently provide any manufacturer drivers.
GPU-Benchmark (OpenCL)
If OpenCL drivers are available for the GPU(s), you can run a benchmark that measures global memory bandwidth with different data widths and transfer bandwidth with different access methods in GBps, as well as computing power in single, double and half Measures accuracy (where supported) with different SIMD data widths (float to float16) in Gflops. An overall score is also calculated from the top values above. The total score can then be compared with other scores and an approximate performance of specific configurations can be calculated.
GPU computing stress test (OpenCL)
If OpenCL drivers are available for the GPU(s), you can run a compute stress test which runs a sequence of the fastest compute and bandwidth tests. The simultaneous use of all cores leads to high utilization. In addition, the GPU's memory is passively tested by the generated computing data.
GPU Memory Test (OpenCL) – Graphics memory test on GPU
Unlike the classic memory test, the GPU memory test uses OpenCL functions. With the OpenCL memory test or graphics card memory test by OpenCL, the entire graphics memory of a GPU is addressed and with different patterns such as Moving Inversions, Walking 8Bit, Walking 32Bit or Random Blocks tested. However, in contrast to the classic GPU memory test, this test is only available on platforms that have a functioning OpenCL implementation. This is usually not a problem under Windows. Limitations within Linux can be expected from Nvidia. However, in most cases Intel and AMD also have support under Linux.
