GeForce RTX 3080 12 GB vs Radeon HD 4870 X2

Intro

Compare that to the Radeon HD 4870 X2, which comes with core clock speeds of 750 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR5 RAM. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3080 12 GB will be 306% quicker than the Radeon HD 4870 X2 in general, due to its higher data rate. (explain)

GeForce RTX 3080 12 GB		934298 MB/sec
Radeon HD 4870 X2		230400 MB/sec
	Difference: 703898 (306%)

Texel Rate

The GeForce RTX 3080 12 GB will be quite a bit (about 488%) faster with regards to texture filtering than the Radeon HD 4870 X2. (explain)

GeForce RTX 3080 12 GB		352800 Mtexels/sec
Radeon HD 4870 X2		60000 Mtexels/sec
	Difference: 292800 (488%)

Pixel Rate

The GeForce RTX 3080 12 GB should be a lot (more or less 488%) faster with regards to AA than the Radeon HD 4870 X2, and also able to handle higher resolutions while still performing well. (explain)

GeForce RTX 3080 12 GB		141120 Mpixels/sec
Radeon HD 4870 X2		24000 Mpixels/sec
	Difference: 117120 (488%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
