GeForce GTX 275 vs GeForce GTX 960

Intro

The GeForce GTX 275 makes use of a 55 nm design. nVidia has clocked the core frequency at 633 MHz. The GDDR3 RAM is set to run at a frequency of 1134 MHz on this card. It features 240 SPUs along with 80 Texture Address Units and 28 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 960, which uses a 28 nm design. nVidia has clocked the core speed at 1127 MHz. The GDDR5 memory works at a frequency of 1750 MHz on this particular model. It features 1024 SPUs as well as 64 TAUs and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, 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 the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
