GeForce GTX 295 vs Radeon RX 6600

Intro

The GeForce GTX 295 makes use of a 55 nm design. nVidia has clocked the core speed at 576 MHz. The GDDR3 memory is set to run at a frequency of 999 MHz on this particular card. It features 240 SPUs as well as 80 Texture Address Units and 28 Rasterization Operator Units.

Compare that to the Radeon RX 6600, which comes with a clock speed of 1626 MHz and a GDDR6 memory speed of 1750 MHz. It also features a 128-bit bus, and uses a 7 nm design. It is comprised of 1792 SPUs, 112 Texture Address Units, and 64 Raster Operation Units.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
