GeForce GT 450 (OEM) vs GeForce GTX 1050

Intro

The GeForce GT 450 (OEM) comes with a clock speed of 790 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 192-bit memory bus, and uses a 40 nm design. It features 144 SPUs, 24 Texture Address Units, and 24 ROPs.

Compare those specifications to the GeForce GTX 1050, which has a core clock speed of 1354 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 128-bit bus, and uses a 14 nm design. It is made up of 640 SPUs, 40 TAUs, and 32 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
