GeForce GT 450 (OEM) vs GeForce GTX 960

Intro

The GeForce GT 450 (OEM) uses a 40 nm design. nVidia has clocked the core frequency at 790 MHz. The GDDR5 RAM is set to run at a frequency of 1000 MHz on this particular card. It features 144 SPUs as well as 24 Texture Address Units and 24 Rasterization Operator Units.

Compare those specs to the GeForce GTX 960, which has GPU clock speed of 1127 MHz, and 2048 MB of GDDR5 memory running at 1750 MHz through a 128-bit bus. It also features 1024 Stream Processors, 64 TAUs, and 32 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video 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 maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
