Radeon HD 5450 vs Radeon R7 M260

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 along with 8 Texture Address Units and 4 Rasterization Operator Units.

Compare those specs to the Radeon R7 M260, which features a core clock frequency of 715 MHz and a DDR3 memory speed of 1000 MHz. It also makes use of a 64-bit bus, and uses a 28 nm design. It is made up of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R7 M260 should in theory be quite a bit superior to the Radeon HD 5450 overall. (explain)

Radeon R7 M260 16000 MB/sec
Radeon HD 5450 12800 MB/sec
Difference: 3200 (25%)

Texel Rate

The Radeon R7 M260 is much (about 230%) better at AF than the Radeon HD 5450. (explain)

Radeon R7 M260 17160 Mtexels/sec
Radeon HD 5450 5200 Mtexels/sec
Difference: 11960 (230%)

Pixel Rate

The Radeon R7 M260 is quite a bit (about 120%) better at full screen anti-aliasing than the Radeon HD 5450, and also should be able to handle higher resolutions better. (explain)

Radeon R7 M260 5720 Mpixels/sec
Radeon HD 5450 2600 Mpixels/sec
Difference: 3120 (120%)

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 max amount of data (measured in megabytes per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units of the card by the core clock 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 processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
