Compare any two graphics cards:
VS

GeForce 8800 GTS (G80) 640MB vs Radeon RX 7900 XT

Intro

The GeForce 8800 GTS (G80) 640MB features a core clock speed of 513 MHz and a GDDR3 memory speed of 792 MHz. It also makes use of a 320-bit memory bus, and makes use of a 90 nm design. It features 96 SPUs, 48 Texture Address Units, and 20 Raster Operation Units.

Compare that to the Radeon RX 7900 XT, which has GPU core speed of 1500 MHz, and 20480 MB of GDDR6 memory set to run at 2500 MHz through a 320-bit bus. It also features 5376 Stream Processors, 336 Texture Address Units, and 192 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. 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 quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
