Geforce GTX 690 vs Radeon RX 6600

Intro

Compare all that to the Radeon RX 6600, which features a core clock frequency of 1626 MHz and a GDDR6 memory speed of 1750 MHz. It also features a 128-bit bus, and makes use of a 7 nm design. It is made up of 1792 SPUs, 112 Texture Address Units, and 64 Raster Operation Units.

Radeon RX 6600		182112 Mtexels/sec
	Difference: 52128 (29%)

Pixel Rate

The Radeon RX 6600 should be quite a bit (more or less 78%) faster with regards to FSAA than the Geforce GTX 690, and will be able to handle higher resolutions more effectively. (explain)

Radeon RX 6600		104064 Mpixels/sec
Geforce GTX 690		58560 Mpixels/sec
	Difference: 45504 (78%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved over the external memory interface in a second. It 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 better the 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 is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, 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 maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
