Radeon HD 4730 vs Radeon R7 M260X

Intro

Compare those specs to the Radeon R7 M260X, which comes with a core clock speed of 825 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It is comprised of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M260X should perform a small bit faster than the Radeon HD 4730 in general. (explain)

Radeon R7 M260X		64000 MB/sec
Radeon HD 4730		57600 MB/sec
	Difference: 6400 (11%)

Texel Rate

The Radeon HD 4730 will be a bit (approximately 13%) more effective at anisotropic filtering than the Radeon R7 M260X. (explain)

Radeon HD 4730		22400 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 2600 (13%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R7 M260X is superior to the Radeon HD 4730, though only just barely. (explain)

Radeon R7 M260X		6600 Mpixels/sec
Radeon HD 4730		5600 Mpixels/sec
	Difference: 1000 (18%)

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 largest amount of data (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its 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 core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
