Radeon R5 M330 vs Radeon R7 M260

Intro

Compare all of that to the Radeon R7 M260, which comes with core speeds of 715 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs along with 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 M260 should be 11% faster than the Radeon R5 M330 overall, because of its higher bandwidth. (explain)

Radeon R7 M260		16000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 1600 (11%)

Texel Rate

The Radeon R5 M330 is a small bit (more or less 20%) more effective at anisotropic filtering than the Radeon R7 M260. (explain)

Radeon R5 M330		20600 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 3440 (20%)

Pixel Rate

The Radeon R5 M330 should be quite a bit (approximately 44%) more effective at anti-aliasing than the Radeon R7 M260, and able to handle higher screen resolutions better. (explain)

Radeon R5 M330		8240 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 2520 (44%)

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 largest amount of information (measured in MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total 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 most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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 fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
