GeForce RTX 3070 vs GeForce RTX 3080

Intro

Compare those specifications to the GeForce RTX 3080, which features GPU clock speed of 1440 MHz, and 10240 MB of GDDR6X memory set to run at 1188 MHz through a 320-bit bus. It also is made up of 8704 Stream Processors, 272 TAUs, 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

In theory, the GeForce RTX 3080 is -100% quicker than the GeForce RTX 3070 overall, due to its greater bandwidth. (explain)

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

Texel Rate

The GeForce RTX 3080 should be a lot (approximately 42%) faster with regards to AF than the GeForce RTX 3070. (explain)

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

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 3070 is superior to the GeForce RTX 3080, but not by far. (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: Bandwidth is the max amount of data (measured in megabytes per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 record to the 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 speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 bandwidth is, the lower the ability to get to the maximum fill rate.
