Radeon R9 280 vs Radeon RX 6650 XT

Intro

The Radeon R9 280 uses a 28 nm design. AMD has clocked the core frequency at 933 MHz. The GDDR5 memory runs at a speed of 1250 MHz on this particular model. It features 1792 SPUs along with 112 TAUs and 32 Rasterization Operator Units.

Compare all of that to the Radeon RX 6650 XT, which makes use of a 7 nm design. AMD has set the core frequency at 2055 MHz. The GDDR6 memory works at a speed of 2190 MHz on this particular card. It features 2048 SPUs along with 128 TAUs and 64 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in one 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 - also called Render Output Units) are responsible for outputting the pixels (image) to 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 bandwidth is, the lower the ability to reach the maximum fill rate.
