Radeon R9 270X vs Radeon RX 6750 XT

Intro

Compare all of that to the Radeon RX 6750 XT, which features GPU core speed of 2150 MHz, and 12288 MB of GDDR6 memory running at 2250 MHz through a 192-bit bus. It also features 2560 SPUs, 160 TAUs, and 64 ROPs.

Radeon R9 270X		180 Watts
Radeon RX 6750 XT		250 Watts
	Difference: 70 Watts (39%)

Memory Bandwidth

In theory, the Radeon RX 6750 XT will be 147% faster than the Radeon R9 270X in general, due to its higher bandwidth. (explain)

Radeon RX 6750 XT		442368 MB/sec
Radeon R9 270X		179200 MB/sec
	Difference: 263168 (147%)

Texel Rate

The Radeon RX 6750 XT is a lot (more or less 330%) better at AF than the Radeon R9 270X. (explain)

Radeon RX 6750 XT		344000 Mtexels/sec
Radeon R9 270X		80000 Mtexels/sec
	Difference: 264000 (330%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6750 XT is the winner, by far. (explain)

Radeon RX 6750 XT		137600 Mpixels/sec
Radeon R9 270X		32000 Mpixels/sec
	Difference: 105600 (330%)

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 megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range 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 figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. 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 lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
