PowerColor HD 7990 V2 review: 51 facts and highlights

1. GPU clock speed

The graphics processing unit (GPU) has a higher clock speed.
950MHz
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.
7.78TFLOPS
Nvidia Titan V: 110TFLOPS

3. pixel rate

The number of pixels that can be rendered to the screen every second.
60.8GPixel/s
Nvidia Quadro GV100: 208.4GPixel/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.
6000MHz
Zotac Gaming GeForce RTX 2080 Ti AMP Extreme: 14400MHz

5. GPU memory speed

The memory clock speed is one aspect that determines the memory bandwidth.
1500MHz
Gainward GeForce GTX 1080 Ti Founders Edition: 5505MHz

6. maximum memory bandwidth

This is the maximum rate that data can be read from or stored into memory.
576GB/s
Asus ROG Strix Radeon RX 570 Gaming OC: 2242GB/s

7. shading units

Shading units (or stream processors) are small processors within the graphics card that are responsible for processing different aspects of the image.
4096
MSI Radeon RX 550 Aero ITX OC: 51232

8. 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.
375W
AMD Radeon HD 6450: 18W

9. texture rate

The number of textured pixels that can be rendered to the screen every second.
144GTexels/s
Nvidia Quadro GV100: 521GTexels/s

10. DirectX version

DirectX is used in games, with newer versions supporting better graphics.
11.1
Colorful GeForce iGame RTX 2080 Ti Advanced OC: 12.1

11. RAM

6GB
Nvidia Quadro GV100: 32.77GB

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.
768bit
Sapphire Radeon Pro Duo: 8192bit

13. 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.
256
XFX Radeon Pro Duo: 512

14. semiconductor size

A smaller size indicates that the process to create the chip is newer.
28nm
AMD Radeon RX 570: 1nm

15. 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.
1.2
XFX Radeon RX 550 Slim Single Slot 4GB: 4.5

16. Supports 4K resolution

Allows you to view in ultra-high definition.

75% have it

17. number of transistors

A higher transistor count generally indicates a newer, more powerful processor.
4313 million
Asus GeForce ROG Strix RTX 2080 Gaming Advanced: 136000 million

18. OpenGL version

OpenGL is used in games, with newer versions supporting better graphics.
4.3
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.
1000MHz
Gigabyte GeForce GTX 1080 Xtreme Gaming: 1936MHz

20. 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.
64
Nvidia Quadro GV100: 128

21. load GPU temperature

A lower load temperature means that the card produces less heat and its cooling system performs better.
82°C
Gigabyte Aorus GeForce RTX 2080 Xtreme 8GB: 0°C
