Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6650 XT		176 Watts
GeForce GTX Titan Black		250 Watts
	Difference: 74 Watts (42%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX Titan Black should be 17% faster than the Radeon RX 6650 XT in general, due to its greater bandwidth. (explain)

GeForce GTX Titan Black		336000 MB/sec
Radeon RX 6650 XT		287072 MB/sec
	Difference: 48928 (17%)

Texel Rate

The Radeon RX 6650 XT will be a lot (about 23%) faster with regards to texture filtering than the GeForce GTX Titan Black. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
GeForce GTX Titan Black		213360 Mtexels/sec
	Difference: 49680 (23%)

Pixel Rate

The Radeon RX 6650 XT should be quite a bit (about 208%) faster with regards to FSAA than the GeForce GTX Titan Black, and also will be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
GeForce GTX Titan Black		42672 Mpixels/sec
	Difference: 88848 (208%)

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 transferred across the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If 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 high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
