Radeon HD 5450 vs Radeon R7 M260

Intro

Compare all that to the Radeon R7 M260, which uses 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 model. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 M260 is 25% faster than the Radeon HD 5450 in general, due to its higher data rate. (explain)

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

Texel Rate

The Radeon R7 M260 will be quite a bit (approximately 230%) better 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 a lot (about 120%) more effective at anti-aliasing than the Radeon HD 5450, and able to handle higher screen 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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be moved over the external memory interface in a 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 memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
