Radeon R9 270X vs Radeon RX 6750 XT

Intro

Compare all of that to the Radeon RX 6750 XT, which comes with core speeds of 2150 MHz on the GPU, and 2250 MHz on the 12288 MB of GDDR6 RAM. It features 2560 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

Radeon R9 270X		179200 MB/sec
	Difference: 263168 (147%)

Texel Rate

The Radeon RX 6750 XT should be a lot (more or less 330%) better at texture filtering 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 running with high levels of AA is important to you, then the Radeon RX 6750 XT is a better choice, by a large margin. (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 maximum amount of information (counted in MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better 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 maximum number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
