Radeon HD 5450 vs Radeon R7 M260

Intro

The Radeon HD 5450 features a GPU core speed of 650 MHz, and the 512 MB of DDR3 RAM runs at 800 MHz through a 64-bit bus. It also is comprised of 80(16x5) Stream Processors, 8 Texture Address Units, and 4 ROPs.

Compare those specs to the Radeon R7 M260, which makes use of a 28 nm design. AMD has set the core frequency at 715 MHz. The DDR3 memory runs at a speed of 1000 MHz on this specific card. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 M260 should be quite a bit faster than the Radeon HD 5450 in general. (explain)

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

Texel Rate

The Radeon R7 M260 should be much (approximately 230%) faster with regards to AF than the Radeon HD 5450. (explain)

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

Pixel Rate

If running with a high screen resolution 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 largest amount of data (measured in MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out 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 applied per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. 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 lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
