GeForce RTX 3070 Ti vs Radeon RX 7900 XTX

Intro

The GeForce RTX 3070 Ti has a core clock frequency of 1575 MHz and a GDDR6X memory frequency of 1188 MHz. It also makes use of a 256-bit bus, and uses a 8 nm design. It features 6144 SPUs, 192 TAUs, and 96 ROPs.

Compare that to the Radeon RX 7900 XTX, which comes with GPU clock speed of 1855 MHz, and 24576 MB of GDDR6 memory running at 2500 MHz through a 384-bit bus. It also features 6144 SPUs, 384 TAUs, and 192 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred past the external memory interface within a second. It's 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 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units of the card 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out 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 also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
