Radeon R5 M230 vs Radeon R7 M260X

Intro

Compare those specs to the Radeon R7 M260X, which has a GPU core clock speed of 825 MHz, and 2048 MB of GDDR5 memory set to run at 1000 MHz through a 128-bit bus. It also is comprised of 384 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R7 M260X should be a lot faster than the Radeon R5 M230 in general. (explain)

Radeon R7 M260X		64000 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 48000 (300%)

Texel Rate

The Radeon R7 M260X is much (more or less 27%) more effective at texture filtering than the Radeon R5 M230. (explain)

Radeon R7 M260X		19800 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 4200 (27%)

Pixel Rate

The Radeon R7 M260X should be quite a bit (more or less 112%) better at FSAA than the Radeon R5 M230, and also capable of handling higher resolutions better. (explain)

Radeon R7 M260X		6600 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 3480 (112%)

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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at 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 that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
