VS

Geforce GTX 770 vs Radeon RX 6600

Intro

The Geforce GTX 770 uses a 28 nm design. nVidia has set the core speed at 1046 MHz. The GDDR5 memory works at a speed of 1753 MHz on this specific card. It features 1536 SPUs as well as 128 TAUs and 32 ROPs.

Compare those specs to the Radeon RX 6600, which uses a 7 nm design. AMD has clocked the core speed at 1626 MHz. The GDDR6 RAM works at a speed of 1750 MHz on this particular model. It features 1792 SPUs as well as 112 Texture Address Units and 64 Rasterization Operator Units.

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 should in theory be a little bit faster than the Geforce GTX 770 in general. (explain)

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

Texel Rate

The Radeon RX 6600 is much (approximately 36%) better at anisotropic 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 superior to the Geforce GTX 770, 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 max amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 applied in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
