Radeon R5 M330 vs Radeon R7 M260X

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, 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 small bit (about 4%) more effective at 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 running with high levels of AA is important to you, then the Radeon R5 M330 is a better choice, and very much so. (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: Bandwidth is the max amount of data (counted in megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, 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 can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
