GeForce GTX Titan X vs Radeon RX 6650 XT

Intro

Compare that to the Radeon RX 6650 XT, which has a GPU core clock speed of 2055 MHz, and 8192 MB of GDDR6 memory running at 2190 MHz through a 128-bit bus. It also is made up of 2048 SPUs, 128 Texture Address Units, and 64 Raster Operation Units.

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

Texel Rate

The Radeon RX 6650 XT will be quite a bit (about 37%) better 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

If running with a high screen resolution is important to you, then the Radeon RX 6650 XT is a better choice, and very much so. (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 max amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If 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 high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video 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 amount of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines 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 fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
