GeForce GTX 1070 vs Radeon RX 6600 XT

Intro

Compare those specifications to the Radeon RX 6600 XT, which has GPU core speed of 1968 MHz, and 8192 MB of GDDR6 RAM running at 2000 MHz through a 128-bit bus. It also is comprised of 2048 SPUs, 128 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1070		150 Watts
Radeon RX 6600 XT		160 Watts
	Difference: 10 Watts (7%)

Memory Bandwidth

Both cards have the exact same bandwidth, so theoretically they should have the same performance. (explain)

Texel Rate

The Radeon RX 6600 XT is quite a bit (approximately 39%) more effective at anisotropic filtering than the GeForce GTX 1070. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
GeForce GTX 1070		180720 Mtexels/sec
	Difference: 71184 (39%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6600 XT is a better choice, by far. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
GeForce GTX 1070		96384 Mpixels/sec
	Difference: 29568 (31%)

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 megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
