Radeon RX 5700 vs Radeon RX 6750 XT

Intro

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

Radeon RX 5700		210960 Mtexels/sec
	Difference: 133040 (63%)

Pixel Rate

The Radeon RX 6750 XT will be a lot (about 47%) more effective at FSAA than the Radeon RX 5700, and also able to handle higher screen resolutions more effectively. (explain)

Radeon RX 6750 XT		137600 Mpixels/sec
Radeon RX 5700		93760 Mpixels/sec
	Difference: 43840 (47%)

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 max amount of data (measured in MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the 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 number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
