GeForce RTX 3070 vs GeForce RTX 4070 Ti

Intro

Compare all that to the GeForce RTX 4070 Ti, which makes use of a 4 nm design. nVidia has clocked the core speed at 2310 MHz. The GDDR6X memory is set to run at a frequency of 1313 MHz on this particular card. It features 7680 SPUs as well as 240 Texture Address Units and 80 ROPs.

GeForce RTX 3070		276000 Mtexels/sec
	Difference: 278400 (101%)

Pixel Rate

The GeForce RTX 4070 Ti is much (more or less 28%) more effective at FSAA than the GeForce RTX 3070, and will be capable of handling higher resolutions more effectively. (explain)

GeForce RTX 4070 Ti		184800 Mpixels/sec
GeForce RTX 3070		144000 Mpixels/sec
	Difference: 40800 (28%)

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 MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling 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 card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
