GeForce RTX 4080 vs Radeon RX 590

Intro

The GeForce RTX 4080 makes use of a 4 nm design. nVidia has clocked the core speed at 2205 MHz. The GDDR6X memory is set to run at a speed of 1400 MHz on this card. It features 9728 SPUs as well as 304 Texture Address Units and 112 Rasterization Operator Units.

Compare all that to the Radeon RX 590, which comes with a clock frequency of 1469 MHz and a GDDR5 memory frequency of 2000 MHz. It also uses a 256-bit memory bus, and uses a 12 nm design. It features 2304 SPUs, 144 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, 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 maximum number of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
