GeForce GTX 650 Ti vs GeForce GTX 950

Intro

The GeForce GTX 650 Ti comes with a GPU core speed of 928 MHz, and the 1024 MB of GDDR5 RAM runs at 1350 MHz through a 128-bit bus. It also is comprised of 768 SPUs, 64 Texture Address Units, and 16 ROPs.

Compare those specifications to the GeForce GTX 950, which uses a 28 nm design. nVidia has clocked the core speed at 1024 MHz. The GDDR5 RAM runs at a speed of 1652 MHz on this specific card. It features 768 SPUs along with 48 TAUs and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 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 amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

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