GeForce RTX 4070 Ti vs Radeon RX 6950 XT

Intro

The GeForce RTX 4070 Ti has a core clock speed of 2310 MHz and a GDDR6X memory speed of 1313 MHz. It also uses a 192-bit memory bus, and uses a 4 nm design. It is comprised of 7680 SPUs, 240 Texture Address Units, and 80 Raster Operation Units.

Compare those specifications to the Radeon RX 6950 XT, which has clock speeds of 1925 MHz on the GPU, and 2250 MHz on the 16384 MB of GDDR6 RAM. It features 5120 SPUs as well as 320 TAUs and 128 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
