GeForce GT 450 (OEM) vs GeForce GTX 1630

Intro

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

Compare all that to the GeForce GTX 1630, which has core speeds of 1740 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR6 RAM. It features 512 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number 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 handling 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 that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. 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 fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
