GeForce RTX 4070 Ti vs GeForce RTX 4080

Intro

Compare those specs to the GeForce RTX 4080, which has GPU core speed of 2205 MHz, and 16384 MB of GDDR6X RAM set to run at 1400 MHz through a 256-bit bus. It also is comprised of 9728 SPUs, 304 TAUs, and 112 Raster Operation Units.

GeForce RTX 4070 Ti		554400 Mtexels/sec
	Difference: 115920 (21%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 4080 is superior to the GeForce RTX 4070 Ti, and very much so. (explain)

GeForce RTX 4080		246960 Mpixels/sec
GeForce RTX 4070 Ti		184800 Mpixels/sec
	Difference: 62160 (34%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 can be processed in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount 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 outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
