GeForce RTX 3070 Ti vs Geforce GTX 770

Intro

Compare all of that to the Geforce GTX 770, which comes with a core clock frequency of 1046 MHz and a GDDR5 memory frequency of 1753 MHz. It also makes use of a 256-bit memory bus, and uses a 28 nm design. It is comprised of 1536 SPUs, 128 TAUs, and 32 ROPs.

Geforce GTX 770		230 Watts
GeForce RTX 3070 Ti		290 Watts
	Difference: 60 Watts (26%)

Memory Bandwidth

As far as performance goes, the GeForce RTX 3070 Ti should in theory be much superior to the Geforce GTX 770 in general. (explain)

GeForce RTX 3070 Ti		622899 MB/sec
Geforce GTX 770		224384 MB/sec
	Difference: 398515 (178%)

Texel Rate

The GeForce RTX 3070 Ti should be a lot (more or less 126%) more effective at anisotropic filtering than the Geforce GTX 770. (explain)

GeForce RTX 3070 Ti		302400 Mtexels/sec
Geforce GTX 770		133888 Mtexels/sec
	Difference: 168512 (126%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 3070 Ti is the winner, by far. (explain)

GeForce RTX 3070 Ti		151200 Mpixels/sec
Geforce GTX 770		33472 Mpixels/sec
	Difference: 117728 (352%)

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 information (measured in megabytes per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR 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 texture units by the core 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 processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
