Geforce GTX 690 vs Radeon RX 6650 XT

Intro

Compare all of that to the Radeon RX 6650 XT, which uses a 7 nm design. AMD has clocked the core frequency at 2055 MHz. The GDDR6 memory works at a frequency of 2190 MHz on this card. It features 2048 SPUs as well as 128 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6650 XT		176 Watts
Geforce GTX 690		300 Watts
	Difference: 124 Watts (70%)

Memory Bandwidth

Theoretically, the Geforce GTX 690 should be quite a bit faster than the Radeon RX 6650 XT overall. (explain)

Geforce GTX 690		384512 MB/sec
Radeon RX 6650 XT		287072 MB/sec
	Difference: 97440 (34%)

Texel Rate

The Radeon RX 6650 XT should be a little bit (about 12%) better at anisotropic filtering than the Geforce GTX 690. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
Geforce GTX 690		234240 Mtexels/sec
	Difference: 28800 (12%)

Pixel Rate

The Radeon RX 6650 XT is a lot (approximately 125%) more effective at AA than the Geforce GTX 690, and should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
Geforce GTX 690		58560 Mpixels/sec
	Difference: 72960 (125%)

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 data (measured in MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video 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 amount of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number 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 filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
