VS

Radeon R9 Nano vs Radeon RX Vega 64

Intro

The Radeon R9 Nano features a GPU clock speed of 1000 MHz, and the 4096 MB of HBM RAM runs at 500 MHz through a 4096-bit bus. It also features 4096 Stream Processors, 256 Texture Address Units, and 64 Raster Operation Units.

Compare those specifications to the Radeon RX Vega 64, which has a clock frequency of 1247 MHz and a HBM2 memory speed of 1890 MHz. It also features a 2048-bit memory bus, and uses a 14 nm design. It is comprised of 4096 SPUs, 256 TAUs, and 64 Raster Operation Units.

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

Texel Rate

The Radeon RX Vega 64 will be much (more or less 25%) faster with regards to 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

If using a high screen resolution is important to you, then the Radeon RX Vega 64 is a better choice, and very much so. (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: Bandwidth is the maximum amount of information (counted in MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 can be processed in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock 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 output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
