GeForce GT 450 (OEM) vs GeForce GTX 1050

Intro

The GeForce GT 450 (OEM) uses a 40 nm design. nVidia has clocked the core frequency at 790 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this particular card. It features 144 SPUs along with 24 Texture Address Units and 24 Rasterization Operator Units.

Compare that to the GeForce GTX 1050, which makes use of a 14 nm design. nVidia has set the core frequency at 1354 MHz. The GDDR5 RAM runs at a frequency of 1750 MHz on this model. It features 640 SPUs along with 40 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
