Radeon R5 M230 vs Radeon R9 M265X

Intro

The Radeon R5 M230 has a clock speed of 780 MHz and a DDR3 memory speed of 1000 MHz. It also uses a 64-bit memory bus, and makes use of a 28 nm design. It features 320 SPUs, 20 Texture Address Units, and 4 ROPs.

Compare those specifications to the Radeon R9 M265X, which features a GPU core clock speed of 575 MHz, and 2048 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M265X should be quite a bit faster than the Radeon R5 M230 in general. (explain)

Radeon R9 M265X 72000 MB/sec
Radeon R5 M230 16000 MB/sec
Difference: 56000 (350%)

Texel Rate

The Radeon R9 M265X is a lot (about 47%) more effective at anisotropic filtering than the Radeon R5 M230. (explain)

Radeon R9 M265X 23000 Mtexels/sec
Radeon R5 M230 15600 Mtexels/sec
Difference: 7400 (47%)

Pixel Rate

The Radeon R9 M265X will be quite a bit (about 195%) better at full screen anti-aliasing than the Radeon R5 M230, and capable of handling higher screen resolutions more effectively. (explain)

Radeon R9 M265X 9200 Mpixels/sec
Radeon R5 M230 3120 Mpixels/sec
Difference: 6080 (195%)

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 (measured in megabytes per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
