Radeon HD 4730 vs Radeon R7 M260X

Intro

Compare those specifications to the Radeon R7 M260X, which uses a 28 nm design. AMD has set the core frequency at 825 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this specific model. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 M260X should theoretically be a small bit faster than the Radeon HD 4730 overall. (explain)

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

Texel Rate

The Radeon HD 4730 is a small bit (about 13%) better 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 using high levels of AA is important to you, then the Radeon R7 M260X is the winner, 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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated 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 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 maximum amount of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
