Compare any two graphics cards:
GeForce GT 450 (OEM) vs GeForce GTX 1630
IntroThe GeForce GT 450 (OEM) has a core clock frequency of 790 MHz and a GDDR5 memory frequency of 1000 MHz. It also features a 192-bit memory bus, and uses a 40 nm design. It is made up of 144 SPUs, 24 Texture Address Units, and 24 ROPs.Compare all of that to the GeForce GTX 1630, which has a core clock frequency of 1740 MHz and a GDDR6 memory frequency of 1500 MHz. It also uses a 64-bit bus, and makes use of a 12 nm design. It is comprised of 512 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 1630 should perform just a bit faster than the GeForce GT 450 (OEM) in general. (explain)
Texel RateThe GeForce GTX 1630 is a lot (approximately 194%) better at texture filtering than the GeForce GT 450 (OEM). (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 1630 is the winner, by a large margin. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 figure is worked out by multiplying the total number 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 applied per second. Pixel Rate: Pixel rate is the maximum number of pixels the video 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 colour ROPs 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 output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
