Compare any two graphics cards:
GeForce GT 450 (OEM) vs GeForce GTX 1630
IntroThe GeForce GT 450 (OEM) features a GPU clock speed of 790 MHz, and the 1536 MB of GDDR5 RAM is set to run at 1000 MHz through a 192-bit bus. It also is comprised of 144 SPUs, 24 Texture Address Units, and 24 ROPs.Compare all of that to the GeForce GTX 1630, which features clock speeds of 1740 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR6 memory. It features 512 SPUs as well as 32 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 1630 should theoretically be just a bit superior to the GeForce GT 450 (OEM) overall. (explain)
Texel RateThe GeForce GTX 1630 is much (more or less 194%) more effective at AF than the GeForce GT 450 (OEM). (explain)
Pixel RateThe GeForce GTX 1630 is a lot (more or less 47%) better at anti-aliasing than the GeForce GT 450 (OEM), and capable of handling higher resolutions without losing too much performance. (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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
