GeForce GT 450 (OEM) vs GeForce GTX 650 Ti 2GB

Intro

The GeForce GT 450 (OEM) uses a 40 nm design. nVidia has clocked the core speed at 790 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this card. It features 144 SPUs along with 24 Texture Address Units and 24 ROPs.

Compare all that to the GeForce GTX 650 Ti 2GB, which has a core clock frequency of 928 MHz and a GDDR5 memory frequency of 1350 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It is made up of 768 SPUs, 64 TAUs, and 16 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. 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 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour 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 is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
