Radeon R9 Nano vs Radeon RX 6800

Intro

Compare those specifications to the Radeon RX 6800, which uses a 7 nm design. AMD has clocked the core frequency at 1700 MHz. The GDDR6 RAM works at a frequency of 2000 MHz on this particular card. It features 3840 SPUs as well as 240 Texture Address Units and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 Nano		175 Watts
Radeon RX 6800		250 Watts
	Difference: 75 Watts (43%)

Memory Bandwidth

As far as performance goes, the Radeon RX 6800 should in theory be just a bit better than the Radeon R9 Nano in general. (explain)

Radeon RX 6800		524288 MB/sec
Radeon R9 Nano		512000 MB/sec
	Difference: 12288 (2%)

Texel Rate

The Radeon RX 6800 should be quite a bit (about 59%) more effective at anisotropic filtering than the Radeon R9 Nano. (explain)

Radeon RX 6800		408000 Mtexels/sec
Radeon R9 Nano		256000 Mtexels/sec
	Difference: 152000 (59%)

Pixel Rate

The Radeon RX 6800 is a lot (about 155%) faster with regards to anti-aliasing than the Radeon R9 Nano, and also able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 6800		163200 Mpixels/sec
Radeon R9 Nano		64000 Mpixels/sec
	Difference: 99200 (155%)

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: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 can be processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling 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 can possibly record to its local memory in one 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 - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
