GeForce GTX 580 vs Radeon RX 6500 XT

Intro

Compare all of that to the Radeon RX 6500 XT, which has GPU core speed of 2200 MHz, and 4096 MB of GDDR6 RAM running at 2250 MHz through a 64-bit bus. It also is comprised of 1024 Stream Processors, 64 Texture Address Units, and 32 Raster Operation Units.

Radeon RX 6500 XT		107 Watts
GeForce GTX 580		244 Watts
	Difference: 137 Watts (128%)

Memory Bandwidth

In theory, the GeForce GTX 580 should be a lot faster than the Radeon RX 6500 XT in general. (explain)

GeForce GTX 580		192384 MB/sec
Radeon RX 6500 XT		147456 MB/sec
	Difference: 44928 (30%)

Texel Rate

The Radeon RX 6500 XT is much (more or less 185%) more effective at AF than the GeForce GTX 580. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
GeForce GTX 580		49408 Mtexels/sec
	Difference: 91392 (185%)

Pixel Rate

The Radeon RX 6500 XT should be quite a bit (approximately 90%) more effective at anti-aliasing than the GeForce GTX 580, and capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce GTX 580		37056 Mpixels/sec
	Difference: 33344 (90%)

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 largest amount of data (in units of MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units 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 applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can 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 the core 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 rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
