GeForce GTX 295 vs GeForce GTX 560

Intro

Compare all that to the GeForce GTX 560, which makes use of a 40 nm design. nVidia has clocked the core speed at 810 MHz. The GDDR5 memory is set to run at a speed of 1001 MHz on this model. It features 336 SPUs along with 56 TAUs and 32 Rasterization Operator Units.

GeForce GTX 560		45360 Mtexels/sec
	Difference: 46800 (103%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 295 is superior to the GeForce GTX 560, by far. (explain)

GeForce GTX 295		32256 Mpixels/sec
GeForce GTX 560		25920 Mpixels/sec
	Difference: 6336 (24%)

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 maximum amount of data (counted in megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units of the card 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 maximum amount of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
