Radeon HD 5450 vs Radeon R5 M230

Intro

The Radeon HD 5450 comes with core speeds of 650 MHz on the GPU, and 800 MHz on the 512 MB of DDR3 RAM. It features 80(16x5) SPUs as well as 8 Texture Address Units and 4 ROPs.

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R5 M230, in theory, should be much faster 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 a lot (more or less 200%) better at AF than the Radeon HD 5450. (explain)

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

Pixel Rate

If running with a high resolution is important to you, then the Radeon R5 M230 is the winner, though only just barely. (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 max amount of information (in units of MB per second) that can be transferred over the external memory interface within a second. It is worked out 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 it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 are applied in one second. This is worked out by multiplying the total texture units by the core clock 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 in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output 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 reach the max fill rate.
