GeForce GTX Titan X vs Radeon RX 6650 XT

Intro

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

Radeon RX 6650 XT		287072 MB/sec
	Difference: 48928 (17%)

Texel Rate

The Radeon RX 6650 XT should be quite a bit (approximately 37%) more effective at texture filtering than the GeForce GTX Titan X. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
GeForce GTX Titan X		192000 Mtexels/sec
	Difference: 71040 (37%)

Pixel Rate

The Radeon RX 6650 XT should be quite a bit (approximately 37%) more effective at full screen anti-aliasing than the GeForce GTX Titan X, and also able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
GeForce GTX Titan X		96000 Mpixels/sec
	Difference: 35520 (37%)

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 largest amount of information (measured in megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 maximum amount of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. 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 is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
