Geforce GTX 690 vs Radeon RX 5700 XT 50th Anniversary Edition

Intro

Compare all of that to the Radeon RX 5700 XT 50th Anniversary Edition, which has a clock frequency of 1680 MHz and a GDDR6 memory speed of 1750 MHz. It also uses a 256-bit bus, and uses a 7 nm design. It is comprised of 2560 SPUs, 160 Texture Address Units, and 64 ROPs.

	Difference: 34560 (15%)

Pixel Rate

The Radeon RX 5700 XT 50th Anniversary Edition will be quite a bit (approximately 84%) better at AA than the Geforce GTX 690, and will be capable of handling higher resolutions while still performing well. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		107520 Mpixels/sec
Geforce GTX 690		58560 Mpixels/sec
	Difference: 48960 (84%)

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 maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
