GeForce RTX 2080 SUPER vs Radeon HD 7970

Intro

Compare all of that to the Radeon HD 7970, which has core speeds of 925 MHz on the GPU, and 1375 MHz on the 3072 MB of GDDR5 memory. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically, the GeForce RTX 2080 SUPER should be much faster than the Radeon HD 7970 overall. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
Radeon HD 7970		264000 MB/sec
	Difference: 243904 (92%)

Texel Rate

The GeForce RTX 2080 SUPER is quite a bit (about 168%) faster with regards to AF than the Radeon HD 7970. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Radeon HD 7970		118400 Mtexels/sec
	Difference: 198400 (168%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 2080 SUPER is superior to the Radeon HD 7970, by far. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon HD 7970		29600 Mpixels/sec
	Difference: 76000 (257%)

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: Memory bandwidth is the max amount of data (in units of MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, the result should 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 high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
