GeForce GTX 960 vs Radeon RX 6600 XT

Intro

Compare all of that to the Radeon RX 6600 XT, which uses a 7 nm design. AMD has set the core frequency at 1968 MHz. The GDDR6 RAM is set to run at a speed of 2000 MHz on this particular model. It features 2048 SPUs as well as 128 TAUs and 64 ROPs.

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% faster than the GeForce GTX 960 overall, 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 is much (more or less 249%) faster with regards to 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 is quite a bit (approximately 249%) better at full screen anti-aliasing than the GeForce GTX 960, and also able to handle higher screen resolutions without losing too much performance. (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 (in units of MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video 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 Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
