Radeon RX 5700 vs Radeon RX 5700 XT

Intro

Compare all of that to the Radeon RX 5700 XT, which makes use of a 7 nm design. AMD has clocked the core frequency at 1605 MHz. The GDDR6 RAM runs at a frequency of 1750 MHz on this particular 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 the exact same bandwidth, so theoretically they should perform exactly the same. (explain)

Texel Rate

The Radeon RX 5700 XT should be much (about 22%) faster with regards to 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

The Radeon RX 5700 XT is a bit (approximately 10%) more effective at AA than the Radeon RX 5700, and also should be able to handle higher resolutions without losing too much performance. (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 max amount of data (counted in megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR 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 number is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

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