Radeon R9 280X vs Radeon RX 6750 XT

Intro

Compare that to the Radeon RX 6750 XT, which uses a 7 nm design. AMD has set the core frequency at 2150 MHz. The GDDR6 memory works at a speed of 2250 MHz on this model. It features 2560 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Radeon RX 6750 XT should perform much 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 should be much (about 216%) better 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

The Radeon RX 6750 XT should be much (approximately 406%) better at anti-aliasing than the Radeon R9 280X, and also will be capable of handling higher 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: Bandwidth is the largest amount of data (in units of MB per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, 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 most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines 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 output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
