Geforce GTX 670 vs Radeon RX 6600

Intro

Compare those specs 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.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the Radeon RX 6600 should be 19% faster than the Geforce GTX 670 overall, because of its greater data rate. (explain)

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

Texel Rate

The Radeon RX 6600 should be much (more or less 78%) more effective at anisotropic filtering than the Geforce GTX 670. (explain)

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

Pixel Rate

The Radeon RX 6600 will be a lot (approximately 255%) better at full screen anti-aliasing than the Geforce GTX 670, and should be capable of handling higher resolutions while still performing well. (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 largest amount of data (measured in megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics 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 can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number 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 outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
