GeForce GT 430 vs GeForce GTX 295

Intro

Compare those specs to the GeForce GTX 295, which has core clock speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 memory. It features 240 SPUs as well as 80 Texture Address Units and 28 Rasterization Operator Units.

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

Memory Bandwidth

In theory, the GeForce GTX 295 should perform quite a bit faster than the GeForce GT 430 in general. (explain)

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

Texel Rate

The GeForce GTX 295 will be much (about 723%) faster with regards to texture filtering than the GeForce GT 430. (explain)

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

Pixel Rate

The GeForce GTX 295 should be a lot (more or less 1052%) faster with regards to anti-aliasing than the GeForce GT 430, and should be capable of handling higher 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: Bandwidth is the max amount of information (measured in megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better 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 a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
