GeForce GTX 960 vs Radeon RX 6650 XT

Intro

Compare those specifications to the Radeon RX 6650 XT, which comes with core clock speeds of 2055 MHz on the GPU, and 2190 MHz on the 8192 MB of GDDR6 memory. It features 2048 SPUs as well as 128 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 960		120 Watts
Radeon RX 6650 XT		176 Watts
	Difference: 56 Watts (47%)

Memory Bandwidth

Performance-wise, the Radeon RX 6650 XT should in theory be quite a bit better than the GeForce GTX 960 in general. (explain)

Radeon RX 6650 XT		287072 MB/sec
GeForce GTX 960		112000 MB/sec
	Difference: 175072 (156%)

Texel Rate

The Radeon RX 6650 XT should be much (approximately 265%) more effective at anisotropic 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 quite a bit (about 265%) better at anti-aliasing than the GeForce GTX 960, and also should be capable of handling higher screen resolutions without slowing down too much. (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: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 number of texture map elements (texels) that are 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 this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
