Radeon R5 M330 vs Radeon R7 M260X

Intro

Compare all of that to the Radeon R7 M260X, which uses a 28 nm design. AMD has clocked the core frequency at 825 MHz. The GDDR5 RAM is set to run at a frequency of 1000 MHz on this particular card. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R7 M260X should perform quite a bit faster than the Radeon R5 M330 in general. (explain)

Radeon R7 M260X		64000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 49600 (344%)

Texel Rate

The Radeon R5 M330 should be a bit (more or less 4%) faster with regards to texture filtering than the Radeon R7 M260X. (explain)

Radeon R5 M330		20600 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 800 (4%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R5 M330 is the winner, by a large margin. (explain)

Radeon R5 M330		8240 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 1640 (25%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better 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 amount of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
