GeForce GT 430 (OEM) vs GeForce GTX 295

Intro

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

GeForce GT 430 (OEM)		60 Watts
GeForce GTX 295		289 Watts
	Difference: 229 Watts (382%)

Memory Bandwidth

In theory, the GeForce GTX 295 should be 677% quicker than the GeForce GT 430 (OEM) overall, because of its greater bandwidth. (explain)

GeForce GTX 295		223776 MB/sec
GeForce GT 430 (OEM)		28800 MB/sec
	Difference: 194976 (677%)

Texel Rate

The GeForce GTX 295 is much (about 723%) more effective at texture filtering than the GeForce GT 430 (OEM). (explain)

GeForce GTX 295		92160 Mtexels/sec
GeForce GT 430 (OEM)		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 (OEM), and very much so. (explain)

GeForce GTX 295		32256 Mpixels/sec
GeForce GT 430 (OEM)		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: Bandwidth is the largest amount of data (measured in MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, the result should 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 AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video 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 most pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
