GeForce RTX 2060 Super vs Radeon HD 6990

Intro

Compare those specs to the Radeon HD 6990, which comes with GPU core speed of 830 MHz, and 2048 MB of GDDR5 RAM set to run at 1250 MHz through a 256-bit bus. It also is comprised of 1536 Stream Processors, 96 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2060 Super		175 Watts
Radeon HD 6990		375 Watts
	Difference: 200 Watts (114%)

Memory Bandwidth

In theory, the GeForce RTX 2060 Super is 43% faster than the Radeon HD 6990 overall, due to its higher data rate. (explain)

GeForce RTX 2060 Super		458752 MB/sec
Radeon HD 6990		320000 MB/sec
	Difference: 138752 (43%)

Texel Rate

The GeForce RTX 2060 Super should be quite a bit (more or less 25%) better at anisotropic filtering than the Radeon HD 6990. (explain)

GeForce RTX 2060 Super		199920 Mtexels/sec
Radeon HD 6990		159360 Mtexels/sec
	Difference: 40560 (25%)

Pixel Rate

The GeForce RTX 2060 Super is a lot (about 77%) faster with regards to anti-aliasing than the Radeon HD 6990, and should be able to handle higher screen resolutions better. (explain)

GeForce RTX 2060 Super		94080 Mpixels/sec
Radeon HD 6990		53120 Mpixels/sec
	Difference: 40960 (77%)

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 MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core 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 fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
