GeForce RTX 3060 vs GeForce RTX 4080

Intro

Compare those specifications to the GeForce RTX 4080, which has a core clock speed of 2205 MHz and a GDDR6X memory speed of 1400 MHz. It also uses a 256-bit bus, and uses a 4 nm design. It is comprised of 9728 SPUs, 304 Texture Address Units, and 112 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3060		170 Watts
GeForce RTX 4080		320 Watts
	Difference: 150 Watts (88%)

Memory Bandwidth

In theory, the GeForce RTX 4080 should perform much faster than the GeForce RTX 3060 overall. (explain)

GeForce RTX 4080		734003 MB/sec
GeForce RTX 3060		368640 MB/sec
	Difference: 365363 (99%)

Texel Rate

The GeForce RTX 4080 will be a lot (more or less 353%) faster with regards to anisotropic filtering than the GeForce RTX 3060. (explain)

GeForce RTX 4080		670320 Mtexels/sec
GeForce RTX 3060		147840 Mtexels/sec
	Difference: 522480 (353%)

Pixel Rate

The GeForce RTX 4080 will be quite a bit (more or less 290%) better at anti-aliasing than the GeForce RTX 3060, and capable of handling higher resolutions without losing too much performance. (explain)

GeForce RTX 4080		246960 Mpixels/sec
GeForce RTX 3060		63360 Mpixels/sec
	Difference: 183600 (290%)

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 (counted in MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once 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, High Dynamic Range 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 number of texture units by the core speed of the chip. The higher this number, the better the 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 number of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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 of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
