Radeon RX 590 vs Radeon RX 6700 XT

Intro

The Radeon RX 590 has a clock frequency of 1469 MHz and a GDDR5 memory frequency of 2000 MHz. It also features a 256-bit bus, and makes use of a 12 nm design. It is comprised of 2304 SPUs, 144 Texture Address Units, and 32 ROPs.

Compare those specs to the Radeon RX 6700 XT, which makes use of a 7 nm design. AMD has set the core frequency at 2321 MHz. The GDDR6 memory runs at a frequency of 2000 MHz on this card. It features 2560 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). 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 potential to get to the max fill rate.
