Geforce GTX 680 vs Radeon RX 6600

Intro

The Geforce GTX 680 makes use of a 28 nm design. nVidia has clocked the core frequency at 1006 MHz. The GDDR5 memory runs at a speed of 1502 MHz on this particular model. It features 1536 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Compare that to the Radeon RX 6600, which has GPU core speed of 1626 MHz, and 8192 MB of GDDR6 RAM running at 1750 MHz through a 128-bit bus. It also is made up of 1792 Stream Processors, 112 TAUs, and 64 Raster Operation Units.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 processed in one second. This is calculated by multiplying the total texture units by the core clock 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 applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write 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 card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
