Geforce GTX 690 vs Radeon RX 6600

Intro

Compare those specifications to the Radeon RX 6600, which makes use of a 7 nm design. AMD has set the core frequency at 1626 MHz. The GDDR6 RAM works at a speed of 1750 MHz on this card. It features 1792 SPUs as well as 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 will be much (more or less 29%) better at AF 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 should be quite a bit (about 78%) more effective at anti-aliasing than the Geforce GTX 690, and also will be capable of handling higher resolutions better. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units of the card by the core clock 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
