Geforce GTX 690 vs Radeon RX 7900 XT

Intro

Compare those specifications to the Radeon RX 7900 XT, which uses a 5 nm design. AMD has clocked the core frequency at 1500 MHz. The GDDR6 RAM is set to run at a speed of 2500 MHz on this card. It features 5376 SPUs along with 336 TAUs and 192 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Performance-wise, the Radeon RX 7900 XT should theoretically be a lot superior to the Geforce GTX 690 in general. (explain)

Radeon RX 7900 XT		819200 MB/sec
Geforce GTX 690		384512 MB/sec
	Difference: 434688 (113%)

Texel Rate

The Radeon RX 7900 XT will be much (more or less 115%) more effective at texture filtering than the Geforce GTX 690. (explain)

Radeon RX 7900 XT		504000 Mtexels/sec
Geforce GTX 690		234240 Mtexels/sec
	Difference: 269760 (115%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 7900 XT is a better choice, by far. (explain)

Radeon RX 7900 XT		288000 Mpixels/sec
Geforce GTX 690		58560 Mpixels/sec
	Difference: 229440 (392%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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