GeForce GTX 970 vs Radeon RX 6600

Intro

The GeForce GTX 970 comes with a clock speed of 1050 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 256-bit memory bus, and makes use of a 28 nm design. It features 1664 SPUs, 104 TAUs, and 64 ROPs.

Compare all of that to the Radeon RX 6600, which uses a 7 nm design. AMD has clocked the core frequency at 1626 MHz. The GDDR6 RAM runs at a frequency of 1750 MHz on this particular card. It features 1792 SPUs along with 112 Texture Address Units and 64 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
