GeForce GTX Titan X vs Radeon RX 6650 XT

Intro

The GeForce GTX Titan X features a core clock frequency of 1000 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 384-bit bus, and makes use of a 28 nm design. It is comprised of 3072 SPUs, 192 Texture Address Units, and 96 ROPs.

Compare those specifications to the Radeon RX 6650 XT, which has GPU core speed of 2055 MHz, and 8192 MB of GDDR6 memory set to run at 2190 MHz through a 128-bit bus. It also is comprised of 2048 Stream Processors, 128 Texture Address Units, and 64 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 are processed per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

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