Radeon R9 280X vs Radeon RX 6750 XT

Intro

Compare those specs to the Radeon RX 6750 XT, which comes with a core clock speed of 2150 MHz and a GDDR6 memory speed of 2250 MHz. It also makes use of a 192-bit bus, and uses a 7 nm design. It is comprised of 2560 SPUs, 160 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Radeon RX 6750 XT will be 54% faster than the Radeon R9 280X overall, due to its higher bandwidth. (explain)

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

Texel Rate

The Radeon RX 6750 XT is much (approximately 216%) better at AF than the Radeon R9 280X. (explain)

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

Pixel Rate

The Radeon RX 6750 XT is much (more or less 406%) better at anti-aliasing than the Radeon R9 280X, and able to handle higher screen resolutions without losing too much performance. (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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, 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 anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its 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 - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
