Radeon HD 5450 vs Radeon R5 M230

Intro

The Radeon HD 5450 features a core clock frequency of 650 MHz and a DDR3 memory frequency of 800 MHz. It also uses a 64-bit bus, and uses a 40 nm design. It features 80(16x5) SPUs, 8 TAUs, and 4 Raster Operation Units.

Compare all of that to the Radeon R5 M230, which comes with clock speeds of 780 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs as well as 20 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R5 M230 should theoretically be a lot better than the Radeon HD 5450 overall. (explain)

Radeon R5 M230 16000 MB/sec
Radeon HD 5450 12800 MB/sec
Difference: 3200 (25%)

Texel Rate

The Radeon R5 M230 will be much (about 200%) more effective at 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 should be just a bit (approximately 20%) better at full screen anti-aliasing than the Radeon HD 5450, and also able to handle higher screen resolutions without losing too much performance. (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: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock 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 output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
