GeForce GTX Titan Black vs Radeon RX 6650 XT

Intro

Compare all of that to the Radeon RX 6650 XT, which comes with GPU clock speed of 2055 MHz, and 8192 MB of GDDR6 RAM set to run at 2190 MHz through a 128-bit bus. It also features 2048 Stream Processors, 128 Texture Address Units, and 64 ROPs.

Radeon RX 6650 XT		176 Watts
GeForce GTX Titan Black		250 Watts
	Difference: 74 Watts (42%)

Memory Bandwidth

As far as performance goes, the GeForce GTX Titan Black should in theory be a little bit superior to the Radeon RX 6650 XT in general. (explain)

GeForce GTX Titan Black		336000 MB/sec
Radeon RX 6650 XT		287072 MB/sec
	Difference: 48928 (17%)

Texel Rate

The Radeon RX 6650 XT is much (more or less 23%) better at anisotropic filtering than the GeForce GTX Titan Black. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
GeForce GTX Titan Black		213360 Mtexels/sec
	Difference: 49680 (23%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6650 XT is a better choice, and very much so. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
GeForce GTX Titan Black		42672 Mpixels/sec
	Difference: 88848 (208%)

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 maximum amount of information (counted in MB per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better 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 most pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core 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 rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
