Compare any two graphics cards:

Radeon R7 370 4G vs Radeon RX 470

Intro

The Radeon R7 370 4G uses a 28 nm design. AMD has clocked the core speed at 975 MHz. The GDDR5 RAM works at a speed of 1400 MHz on this particular model. It features 1024 SPUs as well as 64 Texture Address Units and 32 ROPs.

Compare those specs to the Radeon RX 470, which features clock speeds of 926 MHz on the GPU, and 1650 MHz on the 8192 MB of GDDR5 memory. It features 2048 SPUs along with 128 TAUs and 32 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
