Radeon HD 4730 vs Radeon R7 M260

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 4730 should perform a lot faster than the Radeon R7 M260 overall. (explain)

Radeon HD 4730		57600 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 41600 (260%)

Texel Rate

The Radeon HD 4730 will be much (more or less 31%) more effective at anisotropic filtering than the Radeon R7 M260. (explain)

Radeon HD 4730		22400 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 5240 (31%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R7 M260 is superior to the Radeon HD 4730, but not by far. (explain)

Radeon R7 M260		5720 Mpixels/sec
Radeon HD 4730		5600 Mpixels/sec
	Difference: 120 (2%)

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 information (counted in MB per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If it uses 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 are applied in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory per 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 - also called 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
