VS

Radeon R9 Nano vs Radeon RX 6950 XT

Intro

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

Compare those specs to the Radeon RX 6950 XT, which makes use of a 7 nm design. AMD has set the core speed at 1925 MHz. The GDDR6 RAM runs at a speed of 2250 MHz on this specific card. It features 5120 SPUs as well as 320 TAUs and 128 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the 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 most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out 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 drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
