GeForce GTX Titan Black vs Radeon RX 6650 XT

Intro

Compare all of 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 particular model. 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
GeForce GTX Titan Black		250 Watts
	Difference: 74 Watts (42%)

Memory Bandwidth

In theory, the GeForce GTX Titan Black should be a little bit faster than the Radeon RX 6650 XT overall. (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 should be much (more or less 23%) more effective 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

The Radeon RX 6650 XT is quite a bit (more or less 208%) more effective at full screen anti-aliasing than the GeForce GTX Titan Black, and also will be able to handle higher resolutions without losing too much performance. (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 largest amount of data (counted in MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
