Radeon RX 5700 vs Radeon RX 5700 XT

Intro

Compare all that to the Radeon RX 5700 XT, which uses a 7 nm design. AMD has set the core frequency at 1605 MHz. The GDDR6 memory runs at a speed of 1750 MHz on this specific model. It features 2560 SPUs as well as 160 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700		180 Watts
Radeon RX 5700 XT		225 Watts
	Difference: 45 Watts (25%)

Memory Bandwidth

Both cards have exactly the same bandwidth, so theoretically they should have the same performance. (explain)

Texel Rate

The Radeon RX 5700 XT will be quite a bit (more or less 22%) more effective at texture filtering than the Radeon RX 5700. (explain)

Radeon RX 5700 XT		256800 Mtexels/sec
Radeon RX 5700		210960 Mtexels/sec
	Difference: 45840 (22%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 5700 XT is a better choice, but not by far. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
Radeon RX 5700		93760 Mpixels/sec
	Difference: 8960 (10%)

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 maximum amount of information (in units of megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number 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 clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
