GeForce GT 320 vs GeForce GTX 295

Intro

Compare those specs to the GeForce GTX 295, which makes use of a 55 nm design. nVidia has set the core speed at 576 MHz. The GDDR3 memory runs at a frequency of 999 MHz on this particular model. It features 240 SPUs along with 80 TAUs and 28 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 320		43 Watts
GeForce GTX 295		289 Watts
	Difference: 246 Watts (572%)

Memory Bandwidth

The GeForce GTX 295 should in theory be quite a bit faster than the GeForce GT 320 in general. (explain)

GeForce GTX 295		223776 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 198496 (785%)

Texel Rate

The GeForce GTX 295 is a lot (more or less 611%) faster with regards to anisotropic filtering than the GeForce GT 320. (explain)

GeForce GTX 295		92160 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 79200 (611%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 295 is the winner, by a large margin. (explain)

GeForce GTX 295		32256 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 27936 (647%)

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 data (in units of MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the 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 number is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
