GeForce GT 230 vs GeForce GTX 950M

Intro

The GeForce GT 230 has a GPU clock speed of 550 MHz, and the 1536 MB of DDR3 RAM is set to run at 800 MHz through a 192-bit bus. It also is made up of 32 Stream Processors, 16 Texture Address Units, and 8 Raster Operation Units.

Compare all that to the GeForce GTX 950M, which uses a 28 nm design. nVidia has set the core frequency at 914 MHz. The DDR3 memory works at a speed of 1000 MHz on this model. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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