PowerColor HD 7990 V2: 51 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. floating-point performance

Floating-point performance is a measurement of the raw processing power of the GPU.
Nvidia Titan V: 110TFLOPS

3. pixel rate

The number of pixels that can be rendered to the screen every second.
Zotac GeForce GTX 1080 Ti AMP! Extreme: 154.8GPixel/s

4. 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

5. thermal design power (TDP)

The thermal design power (TDP) is the maximum amount of power the cooling system needs to dissipate. A lower TDP typically means that it consumes less power.
AMD Radeon HD 6450: 18W

6. GPU memory speed

The memory clock speed is one aspect that determines the memory bandwidth.
Gainward GeForce GTX 1080 Ti Founders Edition: 5505MHz

7. maximum memory bandwidth

This is the maximum rate that data can be read from or stored into memory.
Asus ROG Strix Radeon RX 570 Gaming OC: 2242GB/s

8. DirectX version

DirectX is used in games, with newer versions supporting better graphics.
Zotac GeForce GTX Titan X: 12.1

9. 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

10. texture rate

The number of textured pixels that can be rendered to the screen every second.
XFX Radeon Pro Duo: 512GTexels/s

11. RAM

AMD Radeon Pro Duo Polaris: 32GB

12. 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

13. 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

14. 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

15. number of transistors

A higher transistor count generally indicates a newer, more powerful processor.
4313 million
Nvidia Titan V: 21100 million

16. Supports 4K resolution

Allows you to view in ultra-high definition.

74% have it

17. 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

18. OpenGL version

OpenGL is used in games, with newer versions supporting better graphics.
Asus Cerberus GTX 1070 Ti Advanced: 12

19. GPU turbo

When the GPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.
Gigabyte GeForce GTX 1080 Xtreme Gaming: 1936MHz

20. semiconductor size

A smaller size indicates that the process to create the chip is newer.
AMD Radeon RX 570: 1nm

21. has a HDMI output

Devices with a HDMI or mini HDMI port can transfer high definition video and audio to a display.
PowerColor HD 7990 V2
93% have it

22. 3DMark Vantage Texture Fill result

This benchmark is designed to measure graphics performance. Source: AnandTech.
MSI R9 Fury X: 229.9GTexels/s

23. width

MSI Radeon RX 560 Aero ITX OC 2GB: 115mm

24. DVI outputs

Allows you to connect to a display using DVI.
HIS Radeon RX 470 IceQ X2 Turbo: 10

25. load GPU temperature

A lower load temperature means that the card produces less heat and its cooling system performs better.
KFA2 GTX 650 EX OC: 51°C
