GeForce GTX Titan Black vs Radeon RX 6650 XT

Intro

Compare those specs to the Radeon RX 6650 XT, which makes use of a 7 nm design. AMD has set the core speed at 2055 MHz. The GDDR6 memory runs at a speed of 2190 MHz on this card. It features 2048 SPUs as well as 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

Theoretically, the GeForce GTX Titan Black should perform 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 quite a bit (more or less 23%) faster with regards to AF 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 the winner, 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: Bandwidth is the max amount of information (in units of MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 can be applied per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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 ability to get to the max fill rate.
