GeForce GTX 580 vs Radeon RX 6950 XT

Intro

Compare all of that to the Radeon RX 6950 XT, which makes use of a 7 nm design. AMD has clocked the core speed at 1925 MHz. The GDDR6 memory works at a speed of 2250 MHz on this card. It features 5120 SPUs as well as 320 TAUs and 128 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 580		244 Watts
Radeon RX 6950 XT		335 Watts
	Difference: 91 Watts (37%)

Memory Bandwidth

Performance-wise, the Radeon RX 6950 XT should in theory be quite a bit superior to the GeForce GTX 580 in general. (explain)

Radeon RX 6950 XT		589824 MB/sec
GeForce GTX 580		192384 MB/sec
	Difference: 397440 (207%)

Texel Rate

The Radeon RX 6950 XT should be a lot (approximately 1147%) better at texture filtering than the GeForce GTX 580. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
GeForce GTX 580		49408 Mtexels/sec
	Difference: 566592 (1147%)

Pixel Rate

The Radeon RX 6950 XT is quite a bit (about 565%) more effective at AA than the GeForce GTX 580, and also will be capable of handling higher resolutions without slowing down too much. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
GeForce GTX 580		37056 Mpixels/sec
	Difference: 209344 (565%)

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 information (measured in MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount 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 in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
