VS

Geforce GTX 690 vs Radeon RX 6600

Intro

The Geforce GTX 690 features a core clock speed of 915 MHz and a GDDR5 memory frequency of 1502 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It is made up of 1536 SPUs, 128 TAUs, and 32 Raster Operation Units.

Compare all of that to the Radeon RX 6600, which features core 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.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600 132 Watts
Geforce GTX 690 300 Watts
Difference: 168 Watts (127%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 690 should perform much faster than the Radeon RX 6600 overall. (explain)

Geforce GTX 690 384512 MB/sec
Radeon RX 6600 229376 MB/sec
Difference: 155136 (68%)

Texel Rate

The Geforce GTX 690 should be quite a bit (approximately 29%) faster with regards to AF than the Radeon RX 6600. (explain)

Geforce GTX 690 234240 Mtexels/sec
Radeon RX 6600 182112 Mtexels/sec
Difference: 52128 (29%)

Pixel Rate

If running with high levels of AA 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 690 58560 Mpixels/sec
Difference: 45504 (78%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, 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 amount of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
