Radeon R9 280X vs Radeon RX 6750 XT

Intro

Compare all that to the Radeon RX 6750 XT, which has GPU core speed of 2150 MHz, and 12288 MB of GDDR6 RAM set to run at 2250 MHz through a 192-bit bus. It also features 2560 SPUs, 160 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the Radeon RX 6750 XT should perform quite a bit faster than the Radeon R9 280X in general. (explain)

Radeon RX 6750 XT		442368 MB/sec
Radeon R9 280X		288000 MB/sec
	Difference: 154368 (54%)

Texel Rate

The Radeon RX 6750 XT will be quite a bit (approximately 216%) more effective at texture filtering than the Radeon R9 280X. (explain)

Radeon RX 6750 XT		344000 Mtexels/sec
Radeon R9 280X		108800 Mtexels/sec
	Difference: 235200 (216%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6750 XT is superior to the Radeon R9 280X, and very much so. (explain)

Radeon RX 6750 XT		137600 Mpixels/sec
Radeon R9 280X		27200 Mpixels/sec
	Difference: 110400 (406%)

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 maximum amount of data (counted in MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 can be applied in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling 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 chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units 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 rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
