GeForce GTX 960 vs Radeon RX 6600 XT

Intro

Compare those specs to the Radeon RX 6600 XT, which has a GPU core clock 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 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 960		120 Watts
Radeon RX 6600 XT		160 Watts
	Difference: 40 Watts (33%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6600 XT is 134% faster than the GeForce GTX 960 in general, because of its greater bandwidth. (explain)

Radeon RX 6600 XT		262144 MB/sec
GeForce GTX 960		112000 MB/sec
	Difference: 150144 (134%)

Texel Rate

The Radeon RX 6600 XT is a lot (about 249%) better at texture filtering than the GeForce GTX 960. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
GeForce GTX 960		72128 Mtexels/sec
	Difference: 179776 (249%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6600 XT is superior to the GeForce GTX 960, and very much so. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
GeForce GTX 960		36064 Mpixels/sec
	Difference: 89888 (249%)

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 max amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
