Geforce GTX 670 vs Radeon RX 6600

Intro

Compare that to the Radeon RX 6600, which features clock speeds of 1626 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 RAM. It features 1792 SPUs along with 112 Texture Address Units and 64 ROPs.

Radeon RX 6600		132 Watts
Geforce GTX 670		170 Watts
	Difference: 38 Watts (29%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6600 should perform a little bit faster than the Geforce GTX 670 overall. (explain)

Radeon RX 6600		229376 MB/sec
Geforce GTX 670		192000 MB/sec
	Difference: 37376 (19%)

Texel Rate

The Radeon RX 6600 is quite a bit (about 78%) faster with regards to texture filtering than the Geforce GTX 670. (explain)

Radeon RX 6600		182112 Mtexels/sec
Geforce GTX 670		102480 Mtexels/sec
	Difference: 79632 (78%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6600 is the winner, by far. (explain)

Radeon RX 6600		104064 Mpixels/sec
Geforce GTX 670		29280 Mpixels/sec
	Difference: 74784 (255%)

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 data (measured in megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed 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 better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock 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 output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
