Geforce GTX 690 vs Radeon RX 6800 XT

Intro

Compare that to the Radeon RX 6800 XT, which has core speeds of 1825 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 RAM. It features 4608 SPUs along with 288 Texture Address Units and 128 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon RX 6800 XT should in theory be much faster than the Geforce GTX 690 overall. (explain)

Radeon RX 6800 XT		524288 MB/sec
Geforce GTX 690		384512 MB/sec
	Difference: 139776 (36%)

Texel Rate

The Radeon RX 6800 XT will be much (more or less 124%) more effective at anisotropic filtering than the Geforce GTX 690. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
Geforce GTX 690		234240 Mtexels/sec
	Difference: 291360 (124%)

Pixel Rate

The Radeon RX 6800 XT should be a lot (approximately 299%) more effective at anti-aliasing than the Geforce GTX 690, and also will be capable of handling higher resolutions more effectively. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
Geforce GTX 690		58560 Mpixels/sec
	Difference: 175040 (299%)

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 maximum amount of data (in units of MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 can be applied in one second. This is calculated 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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.
