Radeon HD 3650 vs Radeon R7 M260

Intro

Compare all of that to the Radeon R7 M260, which makes use of a 28 nm design. AMD has set the core speed at 715 MHz. The DDR3 memory is set to run at a frequency of 1000 MHz on this particular model. It features 384 SPUs as well as 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 3650 should be 60% faster than the Radeon R7 M260 overall, because of its greater data rate. (explain)

Radeon HD 3650		25600 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 9600 (60%)

Texel Rate

The Radeon R7 M260 will be quite a bit (about 196%) more effective at AF than the Radeon HD 3650. (explain)

Radeon R7 M260		17160 Mtexels/sec
Radeon HD 3650		5800 Mtexels/sec
	Difference: 11360 (196%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R7 M260 is superior to the Radeon HD 3650, by a large margin. (explain)

Radeon R7 M260		5720 Mpixels/sec
Radeon HD 3650		2900 Mpixels/sec
	Difference: 2820 (97%)

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 max amount of data (counted in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, 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 that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
