Geforce GTX 670 vs Radeon RX 6600

Intro

Compare those specifications to the Radeon RX 6600, which uses a 7 nm design. AMD has set the core speed at 1626 MHz. The GDDR6 memory runs at a frequency of 1750 MHz on this particular card. 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 will be 19% faster than the Geforce GTX 670 overall, due to its greater bandwidth. (explain)

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

Texel Rate

The Radeon RX 6600 will be quite a bit (approximately 78%) better at AF than the Geforce GTX 670. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6600 is the winner, by a large margin. (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 information (in units of MB per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 can be applied per 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. 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 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 potential to reach the max fill rate.
