Radeon R7 M260X vs Radeon R9 M275X

Intro

The Radeon R7 M260X has a GPU clock speed of 825 MHz, and the 2048 MB of GDDR5 RAM runs at 1000 MHz through a 128-bit bus. It also is comprised of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Compare that to the Radeon R9 M275X, which features core clock speeds of 900 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M275X, in theory, should perform a little bit faster than the Radeon R7 M260X overall. (explain)

Radeon R9 M275X 72000 MB/sec
Radeon R7 M260X 64000 MB/sec
Difference: 8000 (13%)

Texel Rate

The Radeon R9 M275X is a lot (approximately 82%) better at anisotropic filtering than the Radeon R7 M260X. (explain)

Radeon R9 M275X 36000 Mtexels/sec
Radeon R7 M260X 19800 Mtexels/sec
Difference: 16200 (82%)

Pixel Rate

The Radeon R9 M275X will be a lot (more or less 118%) better at full screen anti-aliasing than the Radeon R7 M260X, and also should be able to handle higher resolutions better. (explain)

Radeon R9 M275X 14400 Mpixels/sec
Radeon R7 M260X 6600 Mpixels/sec
Difference: 7800 (118%)

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 max amount of information (measured in MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high 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 amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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