Radeon R5 M330 vs Radeon R7 M260

Intro

Compare all of that to the Radeon R7 M260, which features a clock speed of 715 MHz and a DDR3 memory frequency of 1000 MHz. It also uses a 64-bit memory bus, and makes use of a 28 nm design. It is comprised of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R7 M260 should in theory be just a bit better than the Radeon R5 M330 in general. (explain)

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

Texel Rate

The Radeon R5 M330 is a little bit (about 20%) more effective at texture 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 much (more or less 44%) faster with regards to full screen anti-aliasing than the Radeon R7 M260, and will be able to handle higher screen resolutions while still performing well. (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: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core 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 fill rate also depends 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.
