Geforce GTX 690 vs Radeon RX 6600

Intro

Compare all that 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 frequency of 1750 MHz on this particular card. It features 1792 SPUs as well as 112 Texture Address Units and 64 Rasterization Operator Units.

Radeon RX 6600		182112 Mtexels/sec
	Difference: 52128 (29%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6600 is a better choice, by a large margin. (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: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the 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 amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
