Geforce GTX 690 vs Radeon RX 6750 XT

Intro

Compare that to the Radeon RX 6750 XT, which makes use of a 7 nm design. AMD has clocked the core frequency at 2150 MHz. The GDDR6 memory works at a speed of 2250 MHz on this specific model. It features 2560 SPUs as well as 160 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6750 XT		250 Watts
Geforce GTX 690		300 Watts
	Difference: 50 Watts (20%)

Memory Bandwidth

In theory, the Radeon RX 6750 XT is 15% quicker than the Geforce GTX 690 in general, due to its greater data rate. (explain)

Radeon RX 6750 XT		442368 MB/sec
Geforce GTX 690		384512 MB/sec
	Difference: 57856 (15%)

Texel Rate

The Radeon RX 6750 XT is quite a bit (more or less 47%) more effective at anisotropic filtering than the Geforce GTX 690. (explain)

Radeon RX 6750 XT		344000 Mtexels/sec
Geforce GTX 690		234240 Mtexels/sec
	Difference: 109760 (47%)

Pixel Rate

The Radeon RX 6750 XT will be a lot (about 135%) more effective at full screen anti-aliasing than the Geforce GTX 690, and should be able to handle higher resolutions better. (explain)

Radeon RX 6750 XT		137600 Mpixels/sec
Geforce GTX 690		58560 Mpixels/sec
	Difference: 79040 (135%)

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 megabytes per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher 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 applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, 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 amount of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. 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 of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
