Gigabyte Radeon R9 390X WindForce 2X: 24 facts and highlights
1. GPU clock speed
The graphics processing unit (GPU) has a higher clock speed.
Gigabyte GeForce GTX 1080 Xtreme Gaming: 1784MHz
2. effective memory speed
The effective memory clock speed is calculated from the size and data rate of the memory. Higher clock speeds can give increased performance in games and other applications.
Nvidia Titan Xp: 11408MHz
3. shading units
Shading units (or stream processors) are small processors within the graphics card that are responsible for processing different aspects of the image.
MSI Radeon RX 550 Aero ITX OC: 51232
4. DirectX version
DirectX is used in games, with newer versions supporting better graphics.
Zotac GeForce GTX Titan X: 12.1
5. memory bus width
A wider bus width means that it can carry more data per cycle. It is an important factor of memory performance, and therefore the general performance of the graphics card.
Sapphire Radeon Pro Duo: 8192bit
AMD Radeon Pro Duo Polaris: 32GB
7. texture mapping units (TMUs)
TMUs take textures and map them to the geometry of a 3D scene. More TMUs will typically mean that texture information is processed faster.
XFX Radeon Pro Duo: 512
8. OpenCL version
Some applications use OpenCL to utilise the power of the graphics processing unit (GPU) for non-graphical computing. Newer versions introduce more functionality and better performance.
XFX Radeon RX 550 Slim Single Slot 4GB: 4.5
9. number of transistors
A higher transistor count generally indicates a newer, more powerful processor.
Nvidia Titan V: 21100 million
10. Supports 4K resolution
Allows you to view in ultra-high definition.
Gigabyte Radeon R9 390X WindForce 2X
74% have it
11. OpenGL version
OpenGL is used in games, with newer versions supporting better graphics.
Asus Cerberus GTX 1070 Ti Advanced: 12
12. semiconductor size
A smaller size indicates that the process to create the chip is newer.
AMD Radeon RX 570: 1nm
13. render output units (ROPs)
The ROPs are responsible for some of the final steps of the rendering process, writing the final pixel data to memory and carrying out other tasks such as anti-aliasing to improve the look of graphics.
PowerColor Radeon R9 295X2: 128
14. has a HDMI output
Devices with a HDMI or mini HDMI port can transfer high definition video and audio to a display.
