Nvidia Titan Xp vs Radeon RX 6650 XT

Intro

Compare those specs to the Radeon RX 6650 XT, which has GPU clock speed of 2055 MHz, and 8192 MB of GDDR6 RAM running 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

Performance-wise, the Nvidia Titan Xp should theoretically be much better 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 (approximately 44%) better at AF 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 using a high screen resolution is important to you, then the Nvidia Titan Xp is a better choice, but it probably won't make a huge difference. (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 (measured in MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 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 clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
