GeForce GTX 970 vs Radeon RX 6600 XT

Intro

The GeForce GTX 970 comes with core speeds of 1050 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 1664 SPUs along with 104 TAUs and 64 Rasterization Operator Units.

Compare those specs to the Radeon RX 6600 XT, which features a core clock speed of 1968 MHz and a GDDR6 memory frequency of 2000 MHz. It also uses a 128-bit bus, and makes use of a 7 nm design. It is made up of 2048 SPUs, 128 TAUs, and 64 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, 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 that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. 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 ability to reach the max fill rate.
