Radeon HD 5450 12800 MB/sec
Difference: 3200 (25%)

Texel Rate

The Radeon R5 M230 is a lot (about 200%) faster with regards to texture filtering than the Radeon HD 5450. (explain)

Radeon R5 M230 15600 Mtexels/sec
Radeon HD 5450 5200 Mtexels/sec
Difference: 10400 (200%)

Pixel Rate

The Radeon R5 M230 is a little bit (about 20%) faster with regards to full screen anti-aliasing than the Radeon HD 5450, and will be able to handle higher resolutions without slowing down too much. (explain)

Radeon R5 M230 3120 Mpixels/sec
Radeon HD 5450 2600 Mpixels/sec
Difference: 520 (20%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per 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 amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
