Radeon RX 5600 XT vs Radeon RX 6650 XT

Intro

The Radeon RX 5600 XT makes use of a 7 nm design. AMD has clocked the core speed at 1375 MHz. The GDDR6 memory works at a speed of 1500 MHz on this particular model. It features 2304 SPUs along with 144 TAUs and 64 Rasterization Operator Units.

Compare all that to the Radeon RX 6650 XT, which features a clock speed of 2055 MHz and a GDDR6 memory speed of 2190 MHz. It also features a 128-bit bus, and makes use of a 7 nm design. It features 2048 SPUs, 128 TAUs, and 64 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video 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 number of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs 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 also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
