Performance
GPU clock speed
902MHz
1392MHz
The graphics processing unit (GPU) has a higher clock speed.
GPU turbo
Unknown. Help us by suggesting a value. (Nvidia GeForce GT 640)
1518MHz
When the GPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.
pixel rate
7.22 GPixel/s
36.43 GPixel/s
The number of pixels that can be rendered to the screen every second.
floating-point performance
0.69 TFLOPS
1.73 TFLOPS
Floating-point performance is a measurement of the raw processing power of the GPU.
texture rate
28.9 GTexels/s
72.86 GTexels/s
The number of textured pixels that can be rendered to the screen every second.
GPU memory speed
891MHz
1752MHz
The memory clock speed is one aspect that determines the memory bandwidth.
shading units
Shading units (or stream processors) are small processors within the graphics card that are responsible for processing different aspects of the image.
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.
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.
Memory
effective memory speed
1782MHz
7008MHz
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 apps.
maximum memory bandwidth
28.5GB/s
112.1GB/s
This is the maximum rate that data can be read from or stored into memory.
VRAM (video RAM) is the dedicated memory of a graphics card. More VRAM generally allows you to run games at higher settings, especially for things like texture resolution.
GDDR version
Newer versions of GDDR memory offer improvements such as higher transfer rates that give increased performance.
memory bus width
128bit
128bit
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.
Supports ECC memory
✖Nvidia GeForce GT 640
✖Nvidia GeForce GTX 1050
Error-correcting code memory can detect and correct data corruption. It is used when is it essential to avoid corruption, such as scientific computing or when running a server.
Features
DirectX version
DirectX is used in games, with newer versions supporting better graphics.
OpenGL version
OpenGL is used in games, with newer versions supporting better graphics.
OpenCL version
Some apps use OpenCL to apply the power of the graphics processing unit (GPU) for non-graphical computing.
Newer versions introduce more functionality and better performance.
Supports multi-display technology
✔Nvidia GeForce GT 640
✖Nvidia GeForce GTX 1050
The graphics card supports multi-display technology. This allows you to configure multiple monitors in order to create a more immersive gaming experience, such as having a wider field of view.
load GPU temperature
Unknown. Help us by suggesting a value. (Nvidia GeForce GT 640)
A lower load temperature means that the card produces less heat and its cooling system performs better.
supports ray tracing
✖Nvidia GeForce GT 640
✖Nvidia GeForce GTX 1050
Ray tracing is an advanced light rendering technique that provides more realistic lighting, shadows, and reflections in games.
Supports 3D
✔Nvidia GeForce GT 640
✔Nvidia GeForce GTX 1050
Allows you to view in 3D (if you have a 3D display and glasses).
supports DLSS
✖Nvidia GeForce GT 640
✖Nvidia GeForce GTX 1050
DLSS (Deep Learning Super Sampling) is an upscaling technology powered by AI. It allows the graphics card to render games at a lower resolution and upscale them to a higher resolution with near-native visual quality and increased performance. DLSS is only available on select games.
PassMark (G3D) result
