GeForce RTX 2060 vs GeForce RTX 4080

Intro

Compare that to the GeForce RTX 4080, which makes use of a 4 nm design. nVidia has set the core speed at 2205 MHz. The GDDR6X RAM is set to run at a frequency of 1400 MHz on this specific card. It features 9728 SPUs as well as 304 Texture Address Units and 112 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2060		160 Watts
GeForce RTX 4080		320 Watts
	Difference: 160 Watts (100%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 4080 is 113% quicker than the GeForce RTX 2060 overall, due to its greater bandwidth. (explain)

GeForce RTX 4080		734003 MB/sec
GeForce RTX 2060		344064 MB/sec
	Difference: 389939 (113%)

Texel Rate

The GeForce RTX 4080 is a lot (approximately 309%) better at anisotropic filtering than the GeForce RTX 2060. (explain)

GeForce RTX 4080		670320 Mtexels/sec
GeForce RTX 2060		163800 Mtexels/sec
	Difference: 506520 (309%)

Pixel Rate

The GeForce RTX 4080 will be quite a bit (more or less 277%) more effective at AA than the GeForce RTX 2060, and also should be capable of handling higher resolutions without losing too much performance. (explain)

GeForce RTX 4080		246960 Mpixels/sec
GeForce RTX 2060		65520 Mpixels/sec
	Difference: 181440 (277%)

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 largest amount of information (counted in megabytes per second) that can be moved past the external memory interface in one 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 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
