Radeon R7 M260X vs Radeon R9 M265X

Intro

Compare all of that to the Radeon R9 M265X, which uses a 28 nm design. AMD has clocked the core speed at 575 MHz. The GDDR5 RAM works at a frequency of 1125 MHz on this specific model. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M265X should in theory be a little bit superior to the Radeon R7 M260X overall. (explain)

Radeon R9 M265X		72000 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The Radeon R9 M265X should be a little bit (approximately 16%) better at texture filtering than the Radeon R7 M260X. (explain)

Radeon R9 M265X		23000 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 3200 (16%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M265X is superior to the Radeon R7 M260X, and very much so. (explain)

Radeon R9 M265X		9200 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 2600 (39%)

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 max amount of information (measured in megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units 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 applied in a second.

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