GeForce GTX 580 3GB vs Radeon RX 6600

Intro

Compare those specifications to the Radeon RX 6600, which makes use of a 7 nm design. AMD has clocked the core frequency at 1626 MHz. The GDDR6 RAM runs at a speed of 1750 MHz on this particular model. It features 1792 SPUs along with 112 Texture Address Units and 64 Rasterization Operator Units.

	Difference: 36992 (19%)

Texel Rate

The Radeon RX 6600 is a lot (approximately 269%) faster with regards to texture filtering than the GeForce GTX 580 3GB. (explain)

Radeon RX 6600		182112 Mtexels/sec
GeForce GTX 580 3GB		49408 Mtexels/sec
	Difference: 132704 (269%)

Pixel Rate

The Radeon RX 6600 will be quite a bit (more or less 181%) better at AA than the GeForce GTX 580 3GB, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 6600		104064 Mpixels/sec
GeForce GTX 580 3GB		37056 Mpixels/sec
	Difference: 67008 (181%)

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: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once 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 anti-aliasing, High Dynamic Range 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 amount of texture units by the core speed of the chip. The better the texel rate, the better the 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 the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
