Nvidia GeForce GTX Titan X vs Nvidia GeForce GTX Titan Z: 33 facts in comparison
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.
XFX Radeon Pro Duo: 16.38TFLOPS
3. pixel rate
The number of pixels that can be rendered to the screen every second.
Asus ROG Strix GeForce GTX 1080 Ti OC: 138.2GPixel/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.
Asus ROG Strix GeForce GTX 1080 Ti OC: 11010MHz
5. DirectX version
DirectX is used in games, with newer versions supporting better graphics.
Zotac GeForce GTX Titan X: 12.1
6. 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
7. 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
8. GPU memory speed
The memory clock speed is one aspect that determines the memory bandwidth.
Gainward GeForce GTX 1080 Ti Founders Edition: 5505MHz
9. 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
10. texture rate
The number of textured pixels that can be rendered to the screen every second.
XFX Radeon Pro Duo: 512GTexels/s
11. number of transistors
A higher transistor count generally indicates a newer, more powerful processor.
Asus ROG Strix RX Vega 64 Gaming OC: 12500 million
0MB more RAM memory.
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.
XFX Radeon Pro Duo: 512
14. 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
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.
XFX Radeon RX 550 Slim Single Slot 4GB: 4.5
16. OpenGL version
OpenGL is used in games, with newer versions supporting better graphics.
Asus ROG Strix RX Vega 64 Gaming: 4.6
17. 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
18. 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
MSI Radeon RX 560 Aero ITX OC 2GB: 115mm
20. DisplayPort outputs
Allows you to connect to a display using DisplayPort.
Nvidia Quadro P4000: 4
21. semiconductor size
A smaller size indicates that the process to create the chip is newer.
AMD Radeon RX 570: 1nm
22. DVI outputs
Allows you to connect to a display using DVI.
HIS Radeon RX 470 IceQ X2 Turbo: 10
23. Supports 3D
Allows you to view in 3D (if you have a 3D display and glasses).
Nvidia GeForce GTX Titan X
Nvidia GeForce GTX Titan Z
89% have it
24. mini DisplayPort outputs
Allows you to connect to a display using mini-DisplayPort.
