Nvidia Titan Xp vs Radeon RX 6650 XT

Intro

Compare all of that to the Radeon RX 6650 XT, which features GPU core speed of 2055 MHz, and 8192 MB of GDDR6 RAM set to run at 2190 MHz through a 128-bit bus. It also is made up of 2048 Stream Processors, 128 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6650 XT		176 Watts
Nvidia Titan Xp		250 Watts
	Difference: 74 Watts (42%)

Memory Bandwidth

Theoretically speaking, the Nvidia Titan Xp should be much faster than the Radeon RX 6650 XT in general. (explain)

Nvidia Titan Xp		560845 MB/sec
Radeon RX 6650 XT		287072 MB/sec
	Difference: 273773 (95%)

Texel Rate

The Nvidia Titan Xp will be quite a bit (more or less 44%) more effective at texture filtering than the Radeon RX 6650 XT. (explain)

Nvidia Titan Xp		379680 Mtexels/sec
Radeon RX 6650 XT		263040 Mtexels/sec
	Difference: 116640 (44%)

Pixel Rate

The Nvidia Titan Xp should be a little bit (approximately 15%) faster with regards to anti-aliasing than the Radeon RX 6650 XT, and also will be able to handle higher screen resolutions without losing too much performance. (explain)

Nvidia Titan Xp		151872 Mpixels/sec
Radeon RX 6650 XT		131520 Mpixels/sec
	Difference: 20352 (15%)

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 information (in units of MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better 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 can be processed in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in a 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 - also 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
