Radeon R7 M260X vs Radeon R9 M265X

Intro

The Radeon R7 M260X uses a 28 nm design. AMD has set the core frequency at 825 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this specific model. It features 384 SPUs as well as 24 TAUs and 8 ROPs.

Compare all of that to the Radeon R9 M265X, which comes with GPU core speed of 575 MHz, and 2048 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R9 M265X should be just a bit faster than the Radeon R7 M260X in general. (explain)

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

Texel Rate

The Radeon R9 M265X is just a bit (more or less 16%) faster with regards to 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

The Radeon R9 M265X will be a lot (approximately 39%) more effective at FSAA than the Radeon R7 M260X, and able to handle higher screen resolutions without losing too much performance. (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: Bandwidth is the max amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 can be applied in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
