VS

Geforce GTX 690 vs Radeon RX 6600

Intro

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

Compare all that to the Radeon RX 6600, which uses a 7 nm design. AMD has clocked the core frequency at 1626 MHz. The GDDR6 memory works at a frequency of 1750 MHz on this model. It features 1792 SPUs as well as 112 Texture Address Units and 64 ROPs.

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

Memory Bandwidth

As far as performance goes, the Geforce GTX 690 should in theory be quite a bit better 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 will be much (more or less 29%) better at texture filtering 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 a high screen resolution 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 maximum amount of data (counted in megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If 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 are applied per second. This figure is calculated by multiplying the total texture units of the card by the core clock 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 in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. 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 many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
