Radeon RX 5700 vs Radeon RX 5700 XT 50th Anniversary Edition

Intro

Compare all that to the Radeon RX 5700 XT 50th Anniversary Edition, which has GPU clock speed of 1680 MHz, and 8096 MB of GDDR6 memory set to run at 1750 MHz through a 256-bit bus. It also 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 50th Anniversary Edition		235 Watts
	Difference: 55 Watts (31%)

Memory Bandwidth

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

Texel Rate

The Radeon RX 5700 XT 50th Anniversary Edition is much (approximately 27%) more effective at texture filtering than the Radeon RX 5700. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		268800 Mtexels/sec
Radeon RX 5700		210960 Mtexels/sec
	Difference: 57840 (27%)

Pixel Rate

The Radeon RX 5700 XT 50th Anniversary Edition should be just a bit (more or less 15%) better at full screen anti-aliasing than the Radeon RX 5700, and will be able to handle higher resolutions without slowing down too much. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		107520 Mpixels/sec
Radeon RX 5700		93760 Mpixels/sec
	Difference: 13760 (15%)

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 (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units 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 is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
