Radeon HD 5450 vs Radeon R5 M230

Intro

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

Compare those specs to the Radeon R5 M230, which features GPU clock speed of 780 MHz, and 2048 MB of DDR3 memory running at 1000 MHz through a 64-bit bus. It also is comprised of 320 Stream Processors, 20 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R5 M230 will be 25% faster than the Radeon HD 5450 overall, because of its higher bandwidth. (explain)

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

Texel Rate

The Radeon R5 M230 should be quite a bit (about 200%) faster with regards to AF 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 will be a little bit (more or less 20%) faster with regards to anti-aliasing than the Radeon HD 5450, and also able to handle higher screen resolutions while still performing well. (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 maximum amount of data (measured in megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 processed per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
