GeForce GTX 970 vs Radeon RX 6600 XT

Intro

Compare all of that to the Radeon RX 6600 XT, which features GPU core speed of 1968 MHz, and 8192 MB of GDDR6 memory set to run at 2000 MHz through a 128-bit bus. It also features 2048 SPUs, 128 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 970		145 Watts
Radeon RX 6600 XT		160 Watts
	Difference: 15 Watts (10%)

Memory Bandwidth

As far as performance goes, the Radeon RX 6600 XT should in theory be just a bit superior to the GeForce GTX 970 overall. (explain)

Radeon RX 6600 XT		262144 MB/sec
GeForce GTX 970		224000 MB/sec
	Difference: 38144 (17%)

Texel Rate

The Radeon RX 6600 XT should be much (approximately 131%) faster with regards to texture filtering than the GeForce GTX 970. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
GeForce GTX 970		109200 Mtexels/sec
	Difference: 142704 (131%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6600 XT is a better choice, by far. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
GeForce GTX 970		67200 Mpixels/sec
	Difference: 58752 (87%)

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 megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be 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 this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
