GeForce GT 430 1GB vs GeForce GTX 295

Intro

Compare all that to the GeForce GTX 295, which uses a 55 nm design. nVidia has clocked the core speed at 576 MHz. The GDDR3 memory is set to run at a frequency of 999 MHz on this specific card. It features 240 SPUs as well as 80 Texture Address Units and 28 Rasterization Operator Units.

GeForce GT 430 1GB		28800 MB/sec
	Difference: 194976 (677%)

Texel Rate

The GeForce GTX 295 will be much (more or less 723%) faster with regards to AF than the GeForce GT 430 1GB. (explain)

GeForce GTX 295		92160 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 80960 (723%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 295 is superior to the GeForce GT 430 1GB, and very much so. (explain)

GeForce GTX 295		32256 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 29456 (1052%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If 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 number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
