Radeon HD 7950 vs Radeon R7 M260X

Intro

Compare that to the Radeon R7 M260X, which has clock speeds of 825 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 RAM. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 7950 is 275% quicker than the Radeon R7 M260X in general, because of its higher data rate. (explain)

Radeon HD 7950		240000 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 176000 (275%)

Texel Rate

The Radeon HD 7950 should be a lot (about 353%) faster with regards to texture filtering than the Radeon R7 M260X. (explain)

Radeon HD 7950		89600 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 69800 (353%)

Pixel Rate

The Radeon HD 7950 is much (more or less 288%) better at AA than the Radeon R7 M260X, and also should be capable of handling higher screen resolutions more effectively. (explain)

Radeon HD 7950		25600 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 19000 (288%)

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 maximum amount of data (in units of MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
