GeForce GTX 960 vs Radeon RX 6600 XT

Intro

Compare that to the Radeon RX 6600 XT, which makes use of a 7 nm design. AMD has clocked the core speed at 1968 MHz. The GDDR6 memory runs at a speed of 2000 MHz on this model. It features 2048 SPUs as well as 128 Texture Address Units and 64 Rasterization Operator 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 will be 134% quicker than the GeForce GTX 960 in general, because of its greater data rate. (explain)

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

Texel Rate

The Radeon RX 6600 XT should be much (more or less 249%) more effective 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

The Radeon RX 6600 XT will be a lot (about 249%) faster with regards to anti-aliasing than the GeForce GTX 960, and will be capable of handling higher screen resolutions while still performing well. (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 maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
