GeForce RTX 2060 vs Radeon HD 6990

Intro

Compare those specs to the Radeon HD 6990, which uses a 40 nm design. AMD has set the core speed at 830 MHz. The GDDR5 RAM works at a speed of 1250 MHz on this specific model. It features 1536 SPUs along with 96 TAUs and 32 ROPs.

Radeon HD 6990		320000 MB/sec
	Difference: 24064 (8%)

Texel Rate

The GeForce RTX 2060 is a small bit (approximately 3%) more effective at anisotropic filtering than the Radeon HD 6990. (explain)

GeForce RTX 2060		163800 Mtexels/sec
Radeon HD 6990		159360 Mtexels/sec
	Difference: 4440 (3%)

Pixel Rate

The GeForce RTX 2060 is quite a bit (about 23%) faster with regards to AA than the Radeon HD 6990, and also should be able to handle higher resolutions while still performing well. (explain)

GeForce RTX 2060		65520 Mpixels/sec
Radeon HD 6990		53120 Mpixels/sec
	Difference: 12400 (23%)

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: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends 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.
