Radeon HD 4550 256MB vs Radeon R5 M230

Intro

The Radeon HD 4550 256MB features core speeds of 600 MHz on the GPU, and 800 MHz on the 256 MB of DDR3 memory. It features 80(16x5) SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Compare those specifications to the Radeon R5 M230, which has a clock frequency of 780 MHz and a DDR3 memory frequency of 1000 MHz. It also makes use of a 64-bit bus, and uses a 28 nm design. It is comprised of 320 SPUs, 20 TAUs, and 4 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it 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 anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip 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 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 drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
