Radeon HD 4550 512MB vs Radeon R5 M230

Intro

The Radeon HD 4550 512MB has a clock frequency of 600 MHz and a GDDR3 memory speed of 800 MHz. It also features a 64-bit bus, and makes use of a 55 nm design. It is made up of 80(16x5) SPUs, 8 Texture Address Units, and 4 ROPs.

Compare those specifications to the Radeon R5 M230, which features a GPU core clock speed of 780 MHz, and 2048 MB of DDR3 RAM set to run at 1000 MHz through a 64-bit bus. It also features 320 SPUs, 20 TAUs, and 4 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 per second. This is calculated by multiplying the total number of texture units of the card by the core 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
