Radeon HD 7990 vs Radeon RX 5600 XT

Intro

The Radeon HD 7990 uses a 28 nm design. AMD has clocked the core frequency at 950 MHz. The GDDR5 RAM is set to run at a frequency of 1500 MHz on this model. It features 2048 SPUs along with 128 TAUs and 32 ROPs.

Compare that to the Radeon RX 5600 XT, which features GPU core speed of 1375 MHz, and 6144 MB of GDDR6 memory set to run at 1500 MHz through a 192-bit bus. It also is made up of 2304 Stream Processors, 144 Texture Address Units, and 64 Raster Operation Units.

Texel Rate

The Radeon HD 7990 should be a lot (approximately 23%) more effective at texture filtering than the Radeon RX 5600 XT. (explain)

Radeon HD 7990 243200 Mtexels/sec
Radeon RX 5600 XT 198000 Mtexels/sec
Difference: 45200 (23%)

Pixel Rate

The Radeon RX 5600 XT is much (about 45%) more effective at FSAA than the Radeon HD 7990, and also able to handle higher resolutions while still performing well. (explain)

Radeon RX 5600 XT 88000 Mpixels/sec
Radeon HD 7990 60800 Mpixels/sec
Difference: 27200 (45%)

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.

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
