GeForce GTX 275 vs GeForce GTX 960

Intro

The GeForce GTX 275 features a clock speed of 633 MHz and a GDDR3 memory speed of 1134 MHz. It also makes use of a 448-bit memory bus, and makes use of a 55 nm design. It features 240 SPUs, 80 TAUs, and 28 Raster Operation Units.

Compare those specs to the GeForce GTX 960, which uses a 28 nm design. nVidia has set the core frequency at 1127 MHz. The GDDR5 memory runs at a frequency of 1750 MHz on this particular card. It features 1024 SPUs along with 64 TAUs and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. 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 of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
