VS

Radeon R9 Nano vs Radeon RX 6750 XT

Intro

The Radeon R9 Nano uses a 28 nm design. AMD has set the core frequency at 1000 MHz. The HBM RAM is set to run at a speed of 500 MHz on this specific card. It features 4096 SPUs along with 256 Texture Address Units and 64 Rasterization Operator Units.

Compare that to the Radeon RX 6750 XT, which features clock speeds of 2150 MHz on the GPU, and 2250 MHz on the 12288 MB of GDDR6 RAM. It features 2560 SPUs along with 160 TAUs and 64 ROPs.

Radeon RX 6750 XT 442368 MB/sec
Difference: 69632 (16%)

Texel Rate

The Radeon RX 6750 XT is much (about 34%) more effective at AF than the Radeon R9 Nano. (explain)

Radeon RX 6750 XT 344000 Mtexels/sec
Radeon R9 Nano 256000 Mtexels/sec
Difference: 88000 (34%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6750 XT is a better choice, by far. (explain)

Radeon RX 6750 XT 137600 Mpixels/sec
Radeon R9 Nano 64000 Mpixels/sec
Difference: 73600 (115%)

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 data (in units of MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, 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 its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount 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 outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
