Radeon HD 4550 256MB vs Radeon R5 M230

Intro

The Radeon HD 4550 256MB features a GPU clock speed of 600 MHz, and the 256 MB of DDR3 memory runs at 800 MHz through a 64-bit bus. It also features 80(16x5) SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Compare those specifications to the Radeon R5 M230, which features a GPU core clock speed of 780 MHz, and 2048 MB of DDR3 memory running at 1000 MHz through a 64-bit bus. It also is made up of 320 SPUs, 20 Texture Address Units, and 4 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the 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 texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, 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 maximum number of pixels that the graphics card could 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 colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
