GeForce GTX Titan vs Radeon RX 6650 XT

Intro

Compare all that to the Radeon RX 6650 XT, which features clock speeds of 2055 MHz on the GPU, and 2190 MHz on the 8192 MB of GDDR6 RAM. 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
GeForce GTX Titan		250 Watts
	Difference: 74 Watts (42%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX Titan should be 0% quicker than the Radeon RX 6650 XT in general, because of its higher data rate. (explain)

GeForce GTX Titan		288384 MB/sec
Radeon RX 6650 XT		287072 MB/sec
	Difference: 1312 (0%)

Texel Rate

The Radeon RX 6650 XT is quite a bit (about 40%) more effective at texture filtering than the GeForce GTX Titan. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
GeForce GTX Titan		187488 Mtexels/sec
	Difference: 75552 (40%)

Pixel Rate

The Radeon RX 6650 XT will be quite a bit (approximately 227%) better at full screen anti-aliasing than the GeForce GTX Titan, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
GeForce GTX Titan		40176 Mpixels/sec
	Difference: 91344 (227%)

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 largest amount of data (in units of MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
