GeForce GT 450 (OEM) vs GeForce GTX 960

Intro

The GeForce GT 450 (OEM) makes use of a 40 nm design. nVidia has set the core frequency at 790 MHz. The GDDR5 memory works at a speed of 1000 MHz on this particular model. It features 144 SPUs along with 24 TAUs and 24 Rasterization Operator Units.

Compare that to the GeForce GTX 960, which features a clock frequency of 1127 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is made up of 1024 SPUs, 64 TAUs, and 32 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that 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 amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
