Radeon HD 4550 256MB vs Radeon R7 M260

Intro

The Radeon HD 4550 256MB uses a 55 nm design. AMD has set the core speed at 600 MHz. The DDR3 RAM works at a frequency of 800 MHz on this specific model. It features 80(16x5) SPUs as well as 8 TAUs and 4 Rasterization Operator Units.

Compare those specifications to the Radeon R7 M260, which comes with GPU core speed of 715 MHz, and 2048 MB of DDR3 memory running at 1000 MHz through a 64-bit bus. It also features 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the interface 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 ANOTHER 2x. The better 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 are applied per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the 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 number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core 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 quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
