GeForce RTX 3070 vs GeForce RTX 3080

Intro

Compare those specs to the GeForce RTX 3080, which makes use of a 8 nm design. nVidia has clocked the core frequency at 1440 MHz. The GDDR6X RAM runs at a frequency of 1188 MHz on this specific model. It features 8704 SPUs as well as 272 Texture Address Units and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3070		220 Watts
GeForce RTX 3080		320 Watts
	Difference: 100 Watts (45%)

Memory Bandwidth

As far as performance goes, the GeForce RTX 3080 should theoretically be a little bit superior to the GeForce RTX 3070 in general. (explain)

GeForce RTX 3080		778547 MB/sec
GeForce RTX 3070		(Unknown) MB/sec
	Difference: 778547 (-100%)

Texel Rate

The GeForce RTX 3080 is much (approximately 42%) more effective at texture filtering than the GeForce RTX 3070. (explain)

GeForce RTX 3080		391680 Mtexels/sec
GeForce RTX 3070		276000 Mtexels/sec
	Difference: 115680 (42%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 3070 is superior to the GeForce RTX 3080, but it probably won't make a huge difference. (explain)

GeForce RTX 3070		144000 Mpixels/sec
GeForce RTX 3080		138240 Mpixels/sec
	Difference: 5760 (4%)

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: Memory bandwidth is the maximum amount of data (in units of MB 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 the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video 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 amount of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core speed of the card. 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 is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
