Radeon HD 6450 (OEM) vs Radeon R5 M230

Intro

The Radeon HD 6450 (OEM) comes with a GPU clock speed of 625 MHz, and the 512 MB of GDDR3 memory runs at 800 MHz through a 64-bit bus. It also is comprised of 160 Stream Processors, 8 Texture Address Units, and 4 Raster Operation Units.

Compare those specifications to the Radeon R5 M230, which features a core clock speed of 780 MHz and a DDR3 memory frequency of 1000 MHz. It also features a 64-bit memory bus, and uses a 28 nm design. It features 320 SPUs, 20 Texture Address Units, and 4 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units 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 maximum number of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
