Compare any two graphics cards:

GeForce GTX 650 vs Radeon RX 5500

Intro

The GeForce GTX 650 has core clock speeds of 1058 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 RAM. It features 384 SPUs along with 32 Texture Address Units and 16 ROPs.

Compare all of that to the Radeon RX 5500, which features GPU clock speed of 1670 MHz, and 4096 MB of GDDR6 RAM set to run at 1750 MHz through a 128-bit bus. It also features 1408 SPUs, 88 Texture Address Units, and 32 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher 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 are processed in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record 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 the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
