GeForce GTX 970 vs Radeon RX 6600

Intro

Compare all of that to the Radeon RX 6600, which comes with core speeds of 1626 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 RAM. It features 1792 SPUs as well as 112 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600		132 Watts
GeForce GTX 970		145 Watts
	Difference: 13 Watts (10%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6600 will be 2% quicker than the GeForce GTX 970 in general, due to its higher data rate. (explain)

Radeon RX 6600		229376 MB/sec
GeForce GTX 970		224000 MB/sec
	Difference: 5376 (2%)

Texel Rate

The Radeon RX 6600 will be a lot (about 67%) faster with regards to anisotropic filtering than the GeForce GTX 970. (explain)

Radeon RX 6600		182112 Mtexels/sec
GeForce GTX 970		109200 Mtexels/sec
	Difference: 72912 (67%)

Pixel Rate

The Radeon RX 6600 will be quite a bit (approximately 55%) more effective at anti-aliasing than the GeForce GTX 970, and able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 6600		104064 Mpixels/sec
GeForce GTX 970		67200 Mpixels/sec
	Difference: 36864 (55%)

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.

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. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
