GeForce RTX 2080 vs GeForce RTX 4070 Ti

Intro

Compare all that to the GeForce RTX 4070 Ti, which has GPU clock speed of 2310 MHz, and 12288 MB of GDDR6X memory set to run at 1313 MHz through a 192-bit bus. It also is made up of 7680 Stream Processors, 240 TAUs, and 80 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2080		215 Watts
GeForce RTX 4070 Ti		285 Watts
	Difference: 70 Watts (33%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 4070 Ti should be 13% quicker than the GeForce RTX 2080 overall, because of its greater bandwidth. (explain)

GeForce RTX 4070 Ti		516096 MB/sec
GeForce RTX 2080		458752 MB/sec
	Difference: 57344 (13%)

Texel Rate

The GeForce RTX 4070 Ti is quite a bit (about 99%) better at anisotropic filtering than the GeForce RTX 2080. (explain)

GeForce RTX 4070 Ti		554400 Mtexels/sec
GeForce RTX 2080		278760 Mtexels/sec
	Difference: 275640 (99%)

Pixel Rate

The GeForce RTX 4070 Ti is quite a bit (about 91%) faster with regards to full screen anti-aliasing than the GeForce RTX 2080, and also should be able to handle higher resolutions better. (explain)

GeForce RTX 4070 Ti		184800 Mpixels/sec
GeForce RTX 2080		96960 Mpixels/sec
	Difference: 87840 (91%)

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 (measured in megabytes per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. 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 output rate is also dependant on many 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.
