GeForce GTX 960 vs Radeon RX 6650 XT

Intro

Compare those specifications to the Radeon RX 6650 XT, which makes use of a 7 nm design. AMD has set the core frequency at 2055 MHz. The GDDR6 memory works at a frequency of 2190 MHz on this particular card. It features 2048 SPUs as well as 128 Texture Address Units and 64 ROPs.

GeForce GTX 960		112000 MB/sec
	Difference: 175072 (156%)

Texel Rate

The Radeon RX 6650 XT will be quite a bit (approximately 265%) more effective at texture filtering than the GeForce GTX 960. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
GeForce GTX 960		72128 Mtexels/sec
	Difference: 190912 (265%)

Pixel Rate

The Radeon RX 6650 XT is much (about 265%) faster with regards to full screen anti-aliasing than the GeForce GTX 960, and also will be able to handle higher screen resolutions better. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
GeForce GTX 960		36064 Mpixels/sec
	Difference: 95456 (265%)

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 information (counted in megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of 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 that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
