GeForce GTX 260 216SP 55 nm vs GeForce GTX 950

Intro

The GeForce GTX 260 216SP 55 nm comes with a core clock speed of 576 MHz and a GDDR3 memory frequency of 999 MHz. It also features a 448-bit bus, and makes use of a 55 nm design. It features 216 SPUs, 72 TAUs, and 28 Raster Operation Units.

Compare those specifications to the GeForce GTX 950, which has GPU core speed of 1024 MHz, and 2048 MB of GDDR5 memory running at 1652 MHz through a 128-bit bus. It also is comprised of 768 SPUs, 48 Texture Address Units, and 32 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

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