GeForce GT 430 1GB vs GeForce GTX 750 Ti

Intro

The GeForce GT 430 1GB makes use of a 40 nm design. nVidia has set the core frequency at 700 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this specific card. It features 96 SPUs along with 16 Texture Address Units and 4 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 750 Ti, which makes use of a 28 nm design. nVidia has set the core frequency at 1020 MHz. The GDDR5 memory runs at a frequency of 1350 MHz on this card. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at 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 that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's 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 output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
