Radeon HD 3650 512MB vs Radeon R7 M260

Intro

The Radeon HD 3650 512MB has a GPU clock speed of 725 MHz, and the 512 MB of GDDR3 RAM is set to run at 800 MHz through a 128-bit bus. It also features 120(24x5) SPUs, 8 Texture Address Units, and 4 ROPs.

Compare all of that to the Radeon R7 M260, which uses a 28 nm design. AMD has set the core frequency at 715 MHz. The DDR3 RAM runs at a frequency of 1000 MHz on this particular card. It features 384 SPUs along with 24 TAUs and 8 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 bandwidth is, the lower the ability to get to the maximum fill rate.
