Radeon HD 5970 vs Radeon RX 5600 XT

Intro

Compare all that to the Radeon RX 5600 XT, which comes with GPU clock speed of 1375 MHz, and 6144 MB of GDDR6 memory running at 1500 MHz through a 192-bit bus. It also is comprised of 2304 Stream Processors, 144 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600 XT		160 Watts
Radeon HD 5970		294 Watts
	Difference: 134 Watts (84%)

Memory Bandwidth

In theory, the Radeon RX 5600 XT is 34% faster than the Radeon HD 5970 in general, due to its greater data rate. (explain)

Radeon RX 5600 XT		344064 MB/sec
Radeon HD 5970		256000 MB/sec
	Difference: 88064 (34%)

Texel Rate

The Radeon HD 5970 is a small bit (approximately 17%) more effective at anisotropic filtering than the Radeon RX 5600 XT. (explain)

Radeon HD 5970		232000 Mtexels/sec
Radeon RX 5600 XT		198000 Mtexels/sec
	Difference: 34000 (17%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 5970 is superior to the Radeon RX 5600 XT, but only just. (explain)

Radeon HD 5970		92800 Mpixels/sec
Radeon RX 5600 XT		88000 Mpixels/sec
	Difference: 4800 (5%)

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 largest amount of information (counted in MB per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR 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 texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
