GeForce GTS 450 1GB vs GeForce GTX 960

Intro

The GeForce GTS 450 1GB has a clock speed of 783 MHz and a GDDR5 memory frequency of 902 MHz. It also features a 128-bit bus, and uses a 40 nm design. It features 192 SPUs, 32 Texture Address Units, and 16 ROPs.

Compare that to the GeForce GTX 960, which makes use of a 28 nm design. nVidia has clocked the core speed at 1127 MHz. The GDDR5 memory is set to run at a speed of 1750 MHz on this card. It features 1024 SPUs along with 64 Texture Address Units and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

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