Radeon HD 4550 256MB vs Radeon R5 M230

Intro

The Radeon HD 4550 256MB comes with a clock frequency of 600 MHz and a DDR3 memory frequency of 800 MHz. It also features a 64-bit memory bus, and makes use of a 55 nm design. It features 80(16x5) SPUs, 8 TAUs, and 4 ROPs.

Compare all that to the Radeon R5 M230, which has core speeds of 780 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 320 SPUs along with 20 Texture Address Units and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R5 M230 should in theory be quite a bit better than the Radeon HD 4550 256MB in general. (explain)

Radeon R5 M230 16000 MB/sec
Radeon HD 4550 256MB 12800 MB/sec
Difference: 3200 (25%)

Texel Rate

The Radeon R5 M230 is much (about 225%) faster with regards to AF than the Radeon HD 4550 256MB. (explain)

Radeon R5 M230 15600 Mtexels/sec
Radeon HD 4550 256MB 4800 Mtexels/sec
Difference: 10800 (225%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R5 M230 is superior to the Radeon HD 4550 256MB, and very much so. (explain)

Radeon R5 M230 3120 Mpixels/sec
Radeon HD 4550 256MB 2400 Mpixels/sec
Difference: 720 (30%)

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 largest amount of data (measured in megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
