Radeon RX 5700 vs Radeon RX 6800

Intro

The Radeon RX 5700 makes use of a 7 nm design. AMD has clocked the core speed at 1465 MHz. The GDDR6 memory runs at a speed of 1750 MHz on this card. It features 2304 SPUs along with 144 TAUs and 64 Rasterization Operator Units.

Compare all that to the Radeon RX 6800, which uses a 7 nm design. AMD has set the core speed at 1700 MHz. The GDDR6 RAM works at a frequency of 2000 MHz on this specific model. It features 3840 SPUs along with 240 Texture Address Units and 96 ROPs.

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

Theoretically speaking, the Radeon RX 6800 will be 14% quicker than the Radeon RX 5700 in general, because of its greater data rate. (explain)

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

Texel Rate

The Radeon RX 6800 should be quite a bit (more or less 93%) better at texture 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 is a lot (approximately 74%) more effective at AA than the Radeon RX 5700, and should be capable of handling higher resolutions more effectively. (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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 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 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 in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs 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 rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
