Compare any two graphics cards:

GeForce GTX 1070 vs Radeon RX 6600

Intro

The GeForce GTX 1070 uses a 16 nm design. nVidia has set the core speed at 1506 MHz. The GDDR5 memory works at a frequency of 2000 MHz on this particular card. It features 1920 SPUs along with 120 TAUs and 64 Rasterization Operator Units.

Compare that to the Radeon RX 6600, which uses a 7 nm design. AMD has clocked the core frequency at 1626 MHz. The GDDR6 RAM is set to run at a frequency of 1750 MHz on this specific model. It features 1792 SPUs as well as 112 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600		132 Watts
GeForce GTX 1070		150 Watts
	Difference: 18 Watts (14%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1070 should be a little bit faster than the Radeon RX 6600 in general. (explain)

GeForce GTX 1070		262144 MB/sec
Radeon RX 6600		229376 MB/sec
	Difference: 32768 (14%)

Texel Rate

The Radeon RX 6600 should be a little bit (more or less 1%) more effective at texture filtering than the GeForce GTX 1070. (explain)

Radeon RX 6600		182112 Mtexels/sec
GeForce GTX 1070		180720 Mtexels/sec
	Difference: 1392 (1%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6600 is the winner, though not by far. (explain)

Radeon RX 6600		104064 Mpixels/sec
GeForce GTX 1070		96384 Mpixels/sec
	Difference: 7680 (8%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs 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 also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
