Radeon R9 Nano vs Radeon RX Vega 64

Intro

The Radeon R9 Nano comes with a GPU clock speed of 1000 MHz, and the 4096 MB of HBM memory is set to run at 500 MHz through a 4096-bit bus. It also features 4096 SPUs, 256 TAUs, and 64 Raster Operation Units.

Compare those specs to the Radeon RX Vega 64, which comes with a clock speed of 1247 MHz and a HBM2 memory speed of 1890 MHz. It also uses a 2048-bit bus, and uses a 14 nm design. It features 4096 SPUs, 256 Texture Address Units, and 64 Raster Operation Units.

Memory Bandwidth

Theoretically speaking, the Radeon R9 Nano is 3% faster than the Radeon RX Vega 64 in general, because of its greater data rate. (explain)

Radeon R9 Nano 512000 MB/sec
Radeon RX Vega 64 495411 MB/sec
Difference: 16589 (3%)

Texel Rate

The Radeon RX Vega 64 is quite a bit (more or less 25%) more effective at AF than the Radeon R9 Nano. (explain)

Radeon RX Vega 64 319232 Mtexels/sec
Radeon R9 Nano 256000 Mtexels/sec
Difference: 63232 (25%)

Pixel Rate

The Radeon RX Vega 64 is much (about 25%) more effective at full screen anti-aliasing than the Radeon R9 Nano, and also should be able to handle higher resolutions while still performing well. (explain)

Radeon RX Vega 64 79808 Mpixels/sec
Radeon R9 Nano 64000 Mpixels/sec
Difference: 15808 (25%)

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 data (in units of megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at 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 figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
