GeForce GT 450 (OEM) vs GeForce GTX 1050 3GB

Intro

The GeForce GT 450 (OEM) features a clock speed of 790 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 192-bit memory bus, and makes use of a 40 nm design. It features 144 SPUs, 24 TAUs, and 24 Raster Operation Units.

Compare all that to the GeForce GTX 1050 3GB, which features a GPU core clock speed of 1392 MHz, and 3072 MB of GDDR5 memory running at 1750 MHz through a 96-bit bus. It also is comprised of 768 Stream Processors, 48 TAUs, and 24 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 can be applied per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's 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 output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
