GeForce GTX 970 vs Radeon RX 6600

Intro

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

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

In theory, the Radeon RX 6600 will be 2% quicker than the GeForce GTX 970 overall, due to its greater bandwidth. (explain)

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

Texel Rate

The Radeon RX 6600 is quite a bit (approximately 67%) better at texture filtering than the GeForce GTX 970. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6600 is superior to the GeForce GTX 970, by far. (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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, 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 anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics 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 card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). 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 ability to get to the max fill rate.
