VisionTek HD 7790 review: 48 facts and highlights

1. GPU clock speed

The graphics processing unit (GPU) has a higher clock speed.
1000MHz
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.
1.79TFLOPS
Nvidia Titan V: 110TFLOPS

3. pixel rate

The number of pixels that can be rendered to the screen every second.
16GPixel/s
Nvidia Quadro P6000: 157.9GPixel/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
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.
85W
AMD Radeon HD 6450: 18W

6. GPU memory speed

The memory clock speed is one aspect that determines the memory bandwidth.
1500MHz
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.
96GB/s
Asus ROG Strix Radeon RX 570 Gaming OC: 2242GB/s

8. shading units

Shading units (or stream processors) are small processors within the graphics card that are responsible for processing different aspects of the image.
896
MSI Radeon RX 550 Aero ITX OC: 51232

9. DirectX version

DirectX is used in games, with newer versions supporting better graphics.
11.1
Zotac GeForce GTX Titan X: 12.1

10. texture rate

The number of textured pixels that can be rendered to the screen every second.
56GTexels/s
XFX Radeon Pro Duo: 512GTexels/s

11. 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.
128bit
Sapphire Radeon Pro Duo: 8192bit

12. RAM

1GB
AMD Radeon Pro Duo Polaris: 32GB

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.
56
XFX Radeon Pro Duo: 512

14. 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

15. Supports 4K resolution

Allows you to view in ultra-high definition.

74% have it

16. number of transistors

A higher transistor count generally indicates a newer, more powerful processor.
2080 million
Nvidia Titan V: 21100 million

17. semiconductor size

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

18. OpenGL version

OpenGL is used in games, with newer versions supporting better graphics.
4.3
Asus Cerberus GTX 1070 Ti Advanced: 12

19. 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.

51.1GTexels/s
MSI R9 Fury X: 229.9GTexels/s

21. load GPU temperature

A lower load temperature means that the card produces less heat and its cooling system performs better.
69°C
KFA2 GTX 650 EX OC: 51°C

22. has a HDMI output

Devices with a HDMI or mini HDMI port can transfer high definition video and audio to a display.
