GeForce GT 430 vs GeForce GTX 295

Intro

Compare all of that to the GeForce GTX 295, which comes with a GPU core clock speed of 576 MHz, and 896 MB of GDDR3 RAM running at 999 MHz through a 448-bit bus. It also is made up of 240 SPUs, 80 TAUs, and 28 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce GTX 295 should be 677% faster than the GeForce GT 430 in general, because of its higher bandwidth. (explain)

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

Texel Rate

The GeForce GTX 295 should be a lot (more or less 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 is much (about 1052%) faster with regards to FSAA than the GeForce GT 430, and capable of handling higher resolutions better. (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 largest amount of data (in units of MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 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, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
