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 is set to run at a frequency of 2190 MHz on this specific card. It features 2048 SPUs as well as 128 TAUs and 64 Rasterization Operator 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

In theory, the Nvidia Titan Xp will be 95% faster than the Radeon RX 6650 XT overall, because of its higher bandwidth. (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 much (approximately 44%) faster with regards to 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

If running with high levels of AA is important to you, then the Nvidia Titan Xp is superior to the Radeon RX 6650 XT, though only just barely. (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: Memory bandwidth is the max amount of information (counted in MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
