Radeon HD 5550 vs Radeon R5 M230

Intro

The Radeon HD 5550 comes with clock speeds of 550 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 RAM. It features 320(64x5) SPUs along with 16 TAUs and 8 ROPs.

Compare all that to the Radeon R5 M230, which features a core clock speed of 780 MHz and a DDR3 memory speed of 1000 MHz. It also uses a 64-bit bus, and uses a 28 nm design. It is made up of 320 SPUs, 20 Texture Address Units, and 4 ROPs.

Radeon R5 M230 16000 MB/sec
Radeon HD 5550 12800 MB/sec
Difference: 3200 (25%)

Texel Rate

The Radeon R5 M230 will be a lot (about 77%) faster with regards to texture filtering than the Radeon HD 5550. (explain)

Radeon R5 M230 15600 Mtexels/sec
Radeon HD 5550 8800 Mtexels/sec
Difference: 6800 (77%)

Pixel Rate

The Radeon HD 5550 should be a lot (approximately 41%) faster with regards to anti-aliasing than the Radeon R5 M230, and also will be able to handle higher screen resolutions better. (explain)

Radeon HD 5550 4400 Mpixels/sec
Radeon R5 M230 3120 Mpixels/sec
Difference: 1280 (41%)

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 MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill 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 reach the max fill rate.
