GeForce GTS 250 512MB vs GeForce GTX 965M

Intro

The GeForce GTS 250 512MB comes with a GPU core speed of 738 MHz, and the 512 MB of GDDR3 memory runs at 1100 MHz through a 256-bit bus. It also features 128 Stream Processors, 64 TAUs, and 16 Raster Operation Units.

Compare all that to the GeForce GTX 965M, which uses a 28 nm design. nVidia has clocked the core frequency at 944 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this particular model. It features 1024 SPUs as well as 64 Texture Address Units and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 are applied in one second. This number is calculated by multiplying the total 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 per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
