Radeon HD 5450 vs Radeon R7 M260

Intro

The Radeon HD 5450 features clock 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 Rasterization Operator Units.

Compare that to the Radeon R7 M260, which makes use of a 28 nm design. AMD has clocked the core speed at 715 MHz. The DDR3 RAM is set to run at a frequency of 1000 MHz on this particular card. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 M260 should in theory perform a lot faster than 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 quite a bit (more or less 230%) faster with regards to anisotropic filtering than the Radeon HD 5450. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the Radeon R7 M260 is the winner, by far. (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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 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 anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
