GeForce GTX Titan Black vs Radeon RX 6650 XT

Intro

The GeForce GTX Titan Black comes with a clock speed of 889 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 384-bit memory bus, and makes use of a 28 nm design. It is made up of 2880 SPUs, 240 Texture Address Units, and 48 ROPs.

Compare all that to the Radeon RX 6650 XT, which has clock speeds of 2055 MHz on the GPU, and 2190 MHz on the 8192 MB of GDDR6 memory. It features 2048 SPUs as well as 128 TAUs and 64 ROPs.

Radeon RX 6650 XT 287072 MB/sec
Difference: 48928 (17%)

Texel Rate

The Radeon RX 6650 XT will be quite a bit (approximately 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

If using a high screen resolution 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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, the result 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 high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure 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 filling the screen with pixels (the image). The actual pixel output 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 max fill rate.
