Radeon HD 6450 (OEM) vs Radeon R5 M230

Intro

The Radeon HD 6450 (OEM) features a clock speed of 625 MHz and a GDDR3 memory speed of 800 MHz. It also makes use of a 64-bit bus, and uses a 40 nm design. It is made up of 160 SPUs, 8 Texture Address Units, and 4 ROPs.

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

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, 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 amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
