Radeon R9 280 vs Radeon RX 6600 XT

Intro

The Radeon R9 280 uses a 28 nm design. AMD has clocked the core speed at 933 MHz. The GDDR5 RAM works at a frequency of 1250 MHz on this particular model. It features 1792 SPUs along with 112 Texture Address Units and 32 ROPs.

Compare all that to the Radeon RX 6600 XT, which comes with clock speeds of 1968 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR6 memory. It features 2048 SPUs along with 128 TAUs and 64 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 texture map elements (texels) that are applied per second. This figure 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 applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines 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 output 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.
