GeForce GTX 950M vs Radeon HD 3650 512MB

Intro

The GeForce GTX 950M uses a 28 nm design. nVidia has set the core frequency at 914 MHz. The DDR3 memory is set to run at a frequency of 1000 MHz on this model. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Compare those specifications to the Radeon HD 3650 512MB, which uses a 55 nm design. AMD has set the core speed at 725 MHz. The GDDR3 memory runs at a speed of 800 MHz on this particular model. It features 120(24x5) SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
