GeForce RTX 3090 vs Radeon RX 6600

Intro

Compare all that to the Radeon RX 6600, which features GPU core speed of 1626 MHz, and 8192 MB of GDDR6 memory set to run at 1750 MHz through a 128-bit bus. It also is comprised of 1792 SPUs, 112 TAUs, and 64 Raster Operation Units.

Radeon RX 6600		229376 MB/sec
	Difference: 729292 (318%)

Texel Rate

The GeForce RTX 3090 should be quite a bit (approximately 151%) more effective at texture filtering than the Radeon RX 6600. (explain)

GeForce RTX 3090		457560 Mtexels/sec
Radeon RX 6600		182112 Mtexels/sec
	Difference: 275448 (151%)

Pixel Rate

The GeForce RTX 3090 will be a lot (approximately 50%) more effective at full screen anti-aliasing than the Radeon RX 6600, and also should be capable of handling higher screen resolutions while still performing well. (explain)

GeForce RTX 3090		156240 Mpixels/sec
Radeon RX 6600		104064 Mpixels/sec
	Difference: 52176 (50%)

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 maximum amount of data (measured in megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
