GeForce GTX Titan vs Radeon RX 6600 XT

Intro

The GeForce GTX Titan comes with a core clock speed of 837 MHz and a GDDR5 memory frequency of 1502 MHz. It also makes use of a 384-bit memory bus, and makes use of a 28 nm design. It features 2688 SPUs, 224 TAUs, and 48 ROPs.

Compare those specifications to the Radeon RX 6600 XT, which uses a 7 nm design. AMD has clocked the core speed at 1968 MHz. The GDDR6 memory runs at a frequency of 2000 MHz on this card. It features 2048 SPUs along with 128 Texture Address Units and 64 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. 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 faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling 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 chip could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
