Radeon RX 460 2GB vs Radeon RX 6950 XT

Intro

The Radeon RX 460 2GB uses a 14 nm design. AMD has set the core frequency at 1090 MHz. The GDDR5 RAM is set to run at a speed of 1750 MHz on this card. It features 896 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Compare all of that to the Radeon RX 6950 XT, which comes with GPU clock speed of 1925 MHz, and 16384 MB of GDDR6 memory set to run at 2250 MHz through a 256-bit bus. It also features 5120 SPUs, 320 TAUs, and 128 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
