Radeon RX 5700 vs Radeon RX 6800

Intro

The Radeon RX 5700 uses a 7 nm design. AMD has set the core frequency at 1465 MHz. The GDDR6 memory works at a frequency of 1750 MHz on this card. It features 2304 SPUs as well as 144 Texture Address Units and 64 Rasterization Operator Units.

Compare those specs to the Radeon RX 6800, which features a core clock frequency of 1700 MHz and a GDDR6 memory frequency of 2000 MHz. It also features a 256-bit memory bus, and uses a 7 nm design. It is comprised of 3840 SPUs, 240 TAUs, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700 180 Watts
Radeon RX 6800 250 Watts
Difference: 70 Watts (39%)

Memory Bandwidth

The Radeon RX 6800 should in theory perform just a bit faster than the Radeon RX 5700 in general. (explain)

Radeon RX 6800 524288 MB/sec
Radeon RX 5700 458752 MB/sec
Difference: 65536 (14%)

Texel Rate

The Radeon RX 6800 is quite a bit (about 93%) more effective at anisotropic filtering than the Radeon RX 5700. (explain)

Radeon RX 6800 408000 Mtexels/sec
Radeon RX 5700 210960 Mtexels/sec
Difference: 197040 (93%)

Pixel Rate

The Radeon RX 6800 will be a lot (about 74%) faster with regards to anti-aliasing than the Radeon RX 5700, and also should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 6800 163200 Mpixels/sec
Radeon RX 5700 93760 Mpixels/sec
Difference: 69440 (74%)

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.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write 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 the core 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
