VS

Radeon R9 Nano vs Radeon RX 6950 XT

Intro

The Radeon R9 Nano makes use of a 28 nm design. AMD has set the core frequency at 1000 MHz. The HBM memory runs at a frequency of 500 MHz on this particular card. It features 4096 SPUs along with 256 TAUs and 64 ROPs.

Compare those specs to the Radeon RX 6950 XT, which comes with clock speeds of 1925 MHz on the GPU, and 2250 MHz on the 16384 MB of GDDR6 RAM. It features 5120 SPUs along with 320 Texture Address Units and 128 Rasterization Operator Units.

Radeon R9 Nano 512000 MB/sec
Difference: 77824 (15%)

Texel Rate

The Radeon RX 6950 XT should be quite a bit (more or less 141%) more effective at texture filtering than the Radeon R9 Nano. (explain)

Radeon RX 6950 XT 616000 Mtexels/sec
Radeon R9 Nano 256000 Mtexels/sec
Difference: 360000 (141%)

Pixel Rate

The Radeon RX 6950 XT is quite a bit (about 285%) more effective at AA than the Radeon R9 Nano, and will be able to handle higher resolutions better. (explain)

Radeon RX 6950 XT 246400 Mpixels/sec
Radeon R9 Nano 64000 Mpixels/sec
Difference: 182400 (285%)

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 maximum amount of information (measured in MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the 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 graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
