Radeon HD 3650 vs Radeon R7 M260

Intro

Compare those specs to the Radeon R7 M260, which comes with clock speeds of 715 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 3650 should theoretically be a lot faster than the Radeon R7 M260 overall. (explain)

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

Texel Rate

The Radeon R7 M260 is much (more or less 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 high levels of AA is important to you, then the Radeon R7 M260 is a better choice, and very much so. (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 maximum amount of data (counted in MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core 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 a 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. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
