GeForce GT 450 (OEM) vs GeForce GTX 1050

Intro

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

Compare those specs to the GeForce GTX 1050, which features a core clock speed of 1354 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 128-bit bus, and uses a 14 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 32 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 can be processed per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the 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 number of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
