Radeon R9 M265X vs Radeon R9 M275X

Intro

The Radeon R9 M265X comes with a GPU core speed of 575 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1125 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

Compare all of that to the Radeon R9 M275X, which comes with a core clock frequency of 900 MHz and a GDDR5 memory frequency of 1125 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It features 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have the exact same bandwidth, so in theory they should have identical performance. (explain)

Texel Rate

The Radeon R9 M275X should be quite a bit (approximately 57%) better at anisotropic filtering than the Radeon R9 M265X. (explain)

Radeon R9 M275X 36000 Mtexels/sec
Radeon R9 M265X 23000 Mtexels/sec
Difference: 13000 (57%)

Pixel Rate

The Radeon R9 M275X should be quite a bit (approximately 57%) more effective at AA than the Radeon R9 M265X, and also should be able to handle higher resolutions without losing too much performance. (explain)

Radeon R9 M275X 14400 Mpixels/sec
Radeon R9 M265X 9200 Mpixels/sec
Difference: 5200 (57%)

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

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 maximum amount of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
