Nvidia Titan Xp vs Radeon RX 6650 XT

Intro

Compare all that to the Radeon RX 6650 XT, which uses a 7 nm design. AMD has clocked the core speed at 2055 MHz. The GDDR6 RAM works at a frequency of 2190 MHz on this specific card. It features 2048 SPUs along with 128 TAUs and 64 ROPs.

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 95% quicker than the Radeon RX 6650 XT overall, due to its greater bandwidth. (explain)

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

Texel Rate

The Nvidia Titan Xp should 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 will be a little bit (about 15%) faster with regards to full screen anti-aliasing than the Radeon RX 6650 XT, and also should be able to handle higher 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 max amount of data (counted in MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, 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 that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
