Radeon R7 M260X vs Radeon R9 M265X

Intro

The Radeon R7 M260X comes with a GPU core speed of 825 MHz, and the 2048 MB of GDDR5 RAM runs at 1000 MHz through a 128-bit bus. It also features 384 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Compare those specs to the Radeon R9 M265X, which comes with a core clock frequency of 575 MHz and a GDDR5 memory frequency of 1125 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M265X should in theory be a small 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 small bit (approximately 16%) more effective at anisotropic 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 high levels of AA 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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video 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 maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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 of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
