GeForce RTX 3080 12 GB vs Geforce GTX 670

Intro

Compare those specifications to the Geforce GTX 670, which uses a 28 nm design. nVidia has clocked the core speed at 915 MHz. The GDDR5 RAM runs at a speed of 1500 MHz on this particular card. It features 1344 SPUs along with 112 Texture Address Units and 32 Rasterization Operator Units.

Geforce GTX 670		192000 MB/sec
	Difference: 742298 (387%)

Texel Rate

The GeForce RTX 3080 12 GB should be a lot (approximately 244%) faster with regards to texture filtering than the Geforce GTX 670. (explain)

GeForce RTX 3080 12 GB		352800 Mtexels/sec
Geforce GTX 670		102480 Mtexels/sec
	Difference: 250320 (244%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 3080 12 GB is superior to the Geforce GTX 670, and very much so. (explain)

GeForce RTX 3080 12 GB		141120 Mpixels/sec
Geforce GTX 670		29280 Mpixels/sec
	Difference: 111840 (382%)

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 max amount of information (counted in MB per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock 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 output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
