Geforce GTX 670 vs Radeon RX 7900 XT

Intro

Compare those specifications to the Radeon RX 7900 XT, which makes use of a 5 nm design. AMD has clocked the core frequency at 1500 MHz. The GDDR6 memory is set to run at a frequency of 2500 MHz on this specific card. It features 5376 SPUs along with 336 Texture Address Units and 192 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Geforce GTX 670		170 Watts
Radeon RX 7900 XT		300 Watts
	Difference: 130 Watts (76%)

Memory Bandwidth

In theory, the Radeon RX 7900 XT will be 327% quicker than the Geforce GTX 670 overall, due to its higher bandwidth. (explain)

Radeon RX 7900 XT		819200 MB/sec
Geforce GTX 670		192000 MB/sec
	Difference: 627200 (327%)

Texel Rate

The Radeon RX 7900 XT should be quite a bit (about 392%) more effective at AF than the Geforce GTX 670. (explain)

Radeon RX 7900 XT		504000 Mtexels/sec
Geforce GTX 670		102480 Mtexels/sec
	Difference: 401520 (392%)

Pixel Rate

The Radeon RX 7900 XT should be a lot (approximately 884%) better at anti-aliasing than the Geforce GTX 670, and should be capable of handling higher screen resolutions better. (explain)

Radeon RX 7900 XT		288000 Mpixels/sec
Geforce GTX 670		29280 Mpixels/sec
	Difference: 258720 (884%)

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: Bandwidth is the max amount of data (in units of megabytes per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
