Geforce GTX 770 vs Radeon RX 6600

Intro

The Geforce GTX 770 comes with a GPU clock speed of 1046 MHz, and the 2048 MB of GDDR5 memory is set to run at 1753 MHz through a 256-bit bus. It also is comprised of 1536 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Compare all of that to the Radeon RX 6600, which makes use of a 7 nm design. AMD has clocked the core frequency at 1626 MHz. The GDDR6 RAM runs at a speed of 1750 MHz on this model. 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 770 230 Watts
Difference: 98 Watts (74%)

Memory Bandwidth

The Radeon RX 6600, in theory, should perform just a bit faster than the Geforce GTX 770 overall. (explain)

Radeon RX 6600 229376 MB/sec
Geforce GTX 770 224384 MB/sec
Difference: 4992 (2%)

Texel Rate

The Radeon RX 6600 should be a lot (more or less 36%) better at texture filtering than the Geforce GTX 770. (explain)

Radeon RX 6600 182112 Mtexels/sec
Geforce GTX 770 133888 Mtexels/sec
Difference: 48224 (36%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6600 is the winner, and very much so. (explain)

Radeon RX 6600 104064 Mpixels/sec
Geforce GTX 770 33472 Mpixels/sec
Difference: 70592 (211%)

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 largest amount of information (measured in MB per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units of the card by the core 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core 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 fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
