GeForce GT 430 vs GeForce GTX 295

Intro

Compare those specs to the GeForce GTX 295, which has a core clock speed of 576 MHz and a GDDR3 memory speed of 999 MHz. It also makes use of a 448-bit bus, and uses a 55 nm design. It is made up of 240 SPUs, 80 TAUs, and 28 Raster Operation Units.

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

Pixel Rate

The GeForce GTX 295 is a lot (about 1052%) faster with regards to full screen anti-aliasing than the GeForce GT 430, and also should be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 295		32256 Mpixels/sec
GeForce GT 430		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 transferred past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, the result 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
