VS

Radeon RX 5700 vs Radeon RX 6800

Intro

The Radeon RX 5700 features core speeds of 1465 MHz on the GPU, and 1750 MHz on the 8096 MB of GDDR6 memory. It features 2304 SPUs along with 144 Texture Address Units and 64 ROPs.

Compare those specs to the Radeon RX 6800, which has core clock speeds of 1700 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 RAM. It features 3840 SPUs as well as 240 TAUs 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 is 14% faster 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 is quite a bit (more or less 93%) better 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 should be a lot (approximately 74%) more effective at anti-aliasing than the Radeon RX 5700, and should be capable of handling higher resolutions better. (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 max amount of information (counted in megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at handling 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 video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
