Radeon RX 580 vs Radeon RX 6650 XT

Intro

The Radeon RX 580 makes use of a 14 nm design. AMD has clocked the core frequency at 1257 MHz. The GDDR5 memory runs at a frequency of 2000 MHz on this specific card. It features 2304 SPUs as well as 144 Texture Address Units and 32 ROPs.

Compare those specs to the Radeon RX 6650 XT, which has clock speeds of 2055 MHz on the GPU, and 2190 MHz on the 8192 MB of GDDR6 RAM. It features 2048 SPUs as well as 128 Texture Address Units and 64 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that can be applied in one 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. 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 also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
