Radeon HD 6450 (OEM) vs Radeon R5 M230

Intro

The Radeon HD 6450 (OEM) comes with a GPU core clock speed of 625 MHz, and the 512 MB of GDDR3 RAM is set to run at 800 MHz through a 64-bit bus. It also is made up of 160 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Compare those specs to the Radeon R5 M230, which makes use of a 28 nm design. AMD has clocked the core frequency at 780 MHz. The DDR3 memory runs at a frequency of 1000 MHz on this particular card. It features 320 SPUs along with 20 TAUs and 4 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of data (measured in MB per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are 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 applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
