Geforce GTX 670 vs Radeon RX 6600

Intro

The Geforce GTX 670 has a clock frequency of 915 MHz and a GDDR5 memory speed of 1500 MHz. It also features a 256-bit memory bus, and makes use of a 28 nm design. It is comprised of 1344 SPUs, 112 TAUs, and 32 ROPs.

Compare all of that to the Radeon RX 6600, which has clock speeds of 1626 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 memory. It features 1792 SPUs as well as 112 TAUs and 64 Rasterization Operator Units.

Geforce GTX 670 192000 MB/sec
Difference: 37376 (19%)

Texel Rate

The Radeon RX 6600 will be much (approximately 78%) faster with regards to 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

If using high levels of AA is important to you, then the Radeon RX 6600 is superior to the Geforce GTX 670, 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.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
