Radeon R7 M260X vs Radeon R9 M370X

Intro

The Radeon R7 M260X features clock speeds of 825 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 memory. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Compare that to the Radeon R9 M370X, which makes use of a 28 nm design. AMD has set the core speed at 800 MHz. The GDDR5 memory works at a speed of 1125 MHz on this particular model. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M370X will be 13% quicker than the Radeon R7 M260X in general, because of its higher bandwidth. (explain)

Radeon R9 M370X 72000 MB/sec
Radeon R7 M260X 64000 MB/sec
Difference: 8000 (13%)

Texel Rate

The Radeon R9 M370X will be much (more or less 62%) better at anisotropic filtering than the Radeon R7 M260X. (explain)

Radeon R9 M370X 32000 Mtexels/sec
Radeon R7 M260X 19800 Mtexels/sec
Difference: 12200 (62%)

Pixel Rate

The Radeon R9 M370X should be much (approximately 94%) faster with regards to anti-aliasing than the Radeon R7 M260X, and also able to handle higher screen resolutions more effectively. (explain)

Radeon R9 M370X 12800 Mpixels/sec
Radeon R7 M260X 6600 Mpixels/sec
Difference: 6200 (94%)

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 data (in units of MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the 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 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 clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
