GeForce GTX Titan Black vs Radeon RX 6650 XT

Intro

The GeForce GTX Titan Black makes use of a 28 nm design. nVidia has set the core frequency at 889 MHz. The GDDR5 memory runs at a speed of 1750 MHz on this specific model. It features 2880 SPUs along with 240 Texture Address Units and 48 Rasterization Operator Units.

Compare those specs 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 speed of 2190 MHz on this particular model. It features 2048 SPUs along with 128 TAUs and 64 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics 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 write to the local memory in a 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 - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
