GeForce GTX 285 1GB vs GeForce GTX 950M

Intro

The GeForce GTX 285 1GB uses a 55 nm design. nVidia has set the core speed at 648 MHz. The GDDR3 RAM works at a frequency of 1242 MHz on this model. It features 240 SPUs along with 80 TAUs and 32 Rasterization Operator Units.

Compare all of that to the GeForce GTX 950M, which comes with clock speeds of 914 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 processed in one second. This number is worked out by multiplying the total amount 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 applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure 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 outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
