GeForce GT 430 1GB vs GeForce GTX 950M

Intro

The GeForce GT 430 1GB makes use of a 40 nm design. nVidia has set the core speed at 700 MHz. The GDDR3 RAM works at a speed of 900 MHz on this specific card. It features 96 SPUs as well as 16 Texture Address Units and 4 ROPs.

Compare all of that to the GeForce GTX 950M, which uses a 28 nm design. nVidia has set the core frequency at 914 MHz. The DDR3 memory works at a speed of 1000 MHz on this specific card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 can be applied in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs 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 fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
