Radeon R9 M270X vs Radeon R9 M275X

Intro

The Radeon R9 M270X comes with a GPU clock speed of 725 MHz, and the 2048 MB of GDDR5 RAM runs at 1125 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 Texture Address Units, and 16 ROPs.

Compare all of 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 as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have the exact same memory bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The Radeon R9 M275X will be a lot (more or less 24%) faster with regards to AF than the Radeon R9 M270X. (explain)

Radeon R9 M275X 36000 Mtexels/sec
Radeon R9 M270X 29000 Mtexels/sec
Difference: 7000 (24%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M275X is superior to the Radeon R9 M270X, and very much so. (explain)

Radeon R9 M275X 14400 Mpixels/sec
Radeon R9 M270X 11600 Mpixels/sec
Difference: 2800 (24%)

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 (in units of MB per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
