GeForce 825M vs GeForce 9500 GT DDR2

Intro

The GeForce 825M has a core clock frequency of 850 MHz and a DDR3 memory speed of 900 MHz. It also makes use of a 64-bit bus, and makes use of a 28 nm design. It features 384 SPUs, 16 TAUs, and 8 ROPs.

Compare all of that to the GeForce 9500 GT DDR2, which comes with a clock frequency of 550 MHz and a DDR2 memory frequency of 500 MHz. It also makes use of a 128-bit memory bus, and uses a 65 nm design. It features 32 SPUs, 16 TAUs, and 8 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
