Compare any two graphics cards:
VS

Geforce GTX 690 vs Radeon RX 6600

Intro

The Geforce GTX 690 features clock speeds of 915 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 RAM. It features 1536 SPUs as well as 128 Texture Address Units and 32 ROPs.

Compare those specifications to the Radeon RX 6600, which has GPU clock speed of 1626 MHz, and 8192 MB of GDDR6 memory set to run at 1750 MHz through a 128-bit bus. It also is comprised of 1792 Stream Processors, 112 Texture Address Units, and 64 ROPs.

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

Performance-wise, the Geforce GTX 690 should theoretically be quite a bit superior to the Radeon RX 6600 in general. (explain)

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

Texel Rate

The Geforce GTX 690 should be a lot (approximately 29%) better at anisotropic filtering than the Radeon RX 6600. (explain)

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

Pixel Rate

The Radeon RX 6600 will be much (more or less 78%) more effective at FSAA than the Geforce GTX 690, and will be able to handle higher screen resolutions more effectively. (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 information (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. 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 ability to reach the max fill rate.
