GeForce 825M vs GeForce 9400 GT 256MB

Intro

The GeForce 825M has a clock speed of 850 MHz and a DDR3 memory speed of 900 MHz. It also makes use of a 64-bit memory bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 16 TAUs, and 8 Raster Operation Units.

Compare those specifications to the GeForce 9400 GT 256MB, which uses a 65 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR2 RAM runs at a frequency of 400 MHz on this specific model. It features 16 SPUs along with 8 TAUs and 4 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
