Geforce GTX 670 vs Radeon RX 6750 XT

Intro

Compare that to the Radeon RX 6750 XT, which comes with a clock frequency of 2150 MHz and a GDDR6 memory frequency of 2250 MHz. It also features a 192-bit bus, and uses a 7 nm design. It is comprised of 2560 SPUs, 160 TAUs, and 64 ROPs.

Geforce GTX 670		170 Watts
Radeon RX 6750 XT		250 Watts
	Difference: 80 Watts (47%)

Memory Bandwidth

Theoretically, the Radeon RX 6750 XT should be much faster than the Geforce GTX 670 in general. (explain)

Radeon RX 6750 XT		442368 MB/sec
Geforce GTX 670		192000 MB/sec
	Difference: 250368 (130%)

Texel Rate

The Radeon RX 6750 XT will be quite a bit (more or less 236%) better at texture filtering than the Geforce GTX 670. (explain)

Radeon RX 6750 XT		344000 Mtexels/sec
Geforce GTX 670		102480 Mtexels/sec
	Difference: 241520 (236%)

Pixel Rate

The Radeon RX 6750 XT should be much (approximately 370%) more effective at full screen anti-aliasing than the Geforce GTX 670, and should be capable of handling higher resolutions better. (explain)

Radeon RX 6750 XT		137600 Mpixels/sec
Geforce GTX 670		29280 Mpixels/sec
	Difference: 108320 (370%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be moved past the external memory interface within a second. It is 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 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
