GeForce GTX 970 vs GeForce RTX 3080 Ti

Intro

Compare all of that to the GeForce RTX 3080 Ti, which has GPU clock speed of 1365 MHz, and 12288 MB of GDDR6X RAM running at 1188 MHz through a 384-bit bus. It also is made up of 10240 SPUs, 320 Texture Address Units, and 112 ROPs.

GeForce GTX 970		109200 Mtexels/sec
	Difference: 327600 (300%)

Pixel Rate

The GeForce RTX 3080 Ti is a lot (about 128%) more effective at anti-aliasing than the GeForce GTX 970, and able to handle higher screen resolutions while still performing well. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
GeForce GTX 970		67200 Mpixels/sec
	Difference: 85680 (128%)

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 maximum amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock 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 in a second.

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