Radeon RX 5700 vs Radeon RX 5700 XT

Intro

Compare all that to the Radeon RX 5700 XT, which has a core clock frequency of 1605 MHz and a GDDR6 memory speed of 1750 MHz. It also makes use of a 256-bit bus, and makes use of a 7 nm design. It is comprised of 2560 SPUs, 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 in theory they should perform the same. (explain)

Texel Rate

The Radeon RX 5700 XT is quite a bit (more or less 22%) faster with regards to AF 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 running with a high resolution is important to you, then the Radeon RX 5700 XT is a better choice, but only just. (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 largest amount of information (counted in megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's interface 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 AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
