GeForce RTX 3060 vs Radeon HD 6990

Intro

Compare those specifications to the Radeon HD 6990, which uses a 40 nm design. AMD has clocked the core speed at 830 MHz. The GDDR5 RAM works at a frequency of 1250 MHz on this specific card. It features 1536 SPUs as well as 96 Texture Address Units and 32 Rasterization Operator Units.

Texel Rate

The Radeon HD 6990 should be a bit (about 8%) better at AF than the GeForce RTX 3060. (explain)

Radeon HD 6990		159360 Mtexels/sec
GeForce RTX 3060		147840 Mtexels/sec
	Difference: 11520 (8%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 3060 is superior to the Radeon HD 6990, but not by far. (explain)

GeForce RTX 3060		63360 Mpixels/sec
Radeon HD 6990		53120 Mpixels/sec
	Difference: 10240 (19%)

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 max amount of data (in units of MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics 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 most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
