Radeon HD 5450 vs Radeon R7 M260

Intro

Compare all of that to the Radeon R7 M260, which features a core clock frequency of 715 MHz and a DDR3 memory frequency of 1000 MHz. It also features a 64-bit bus, and makes use of 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 theoretically be quite a bit better 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 will be much (approximately 230%) more effective at 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

The Radeon R7 M260 should be quite a bit (more or less 120%) more effective at anti-aliasing than the Radeon HD 5450, and should be capable of handling higher resolutions more effectively. (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.

Specifications

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

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
