Compare any two graphics cards:
VS

Geforce GTX 690 vs Radeon RX 6700 XT

Intro

The Geforce GTX 690 makes use of a 28 nm design. nVidia has clocked the core frequency at 915 MHz. The GDDR5 memory works at a frequency of 1502 MHz on this card. It features 1536 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

Compare all of that to the Radeon RX 6700 XT, which features a GPU core clock speed of 2321 MHz, and (Unknown) MB of GDDR6 memory set to run at 2000 MHz through a 192-bit bus. It also is made up of 2560 SPUs, 160 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6700 XT 230 Watts
Geforce GTX 690 300 Watts
Difference: 70 Watts (30%)

Memory Bandwidth

Theoretically, the Radeon RX 6700 XT should perform just a bit faster than the Geforce GTX 690 overall. (explain)

Radeon RX 6700 XT 393216 MB/sec
Geforce GTX 690 384512 MB/sec
Difference: 8704 (2%)

Texel Rate

The Radeon RX 6700 XT will be much (approximately 59%) more effective at anisotropic filtering than the Geforce GTX 690. (explain)

Radeon RX 6700 XT 371360 Mtexels/sec
Geforce GTX 690 234240 Mtexels/sec
Difference: 137120 (59%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 6700 XT is the winner, and very much so. (explain)

Radeon RX 6700 XT 148544 Mpixels/sec
Geforce GTX 690 58560 Mpixels/sec
Difference: 89984 (154%)

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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure 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 outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
