GeForce GTX 295 vs GeForce GTX 560

Intro

Compare those specs to the GeForce GTX 560, which uses a 40 nm design. nVidia has set the core speed at 810 MHz. The GDDR5 memory is set to run at a frequency of 1001 MHz on this specific card. It features 336 SPUs along with 56 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 560		150 Watts
GeForce GTX 295		289 Watts
	Difference: 139 Watts (93%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 295 should in theory be a lot superior to the GeForce GTX 560 in general. (explain)

GeForce GTX 295		223776 MB/sec
GeForce GTX 560		128128 MB/sec
	Difference: 95648 (75%)

Texel Rate

The GeForce GTX 295 will be quite a bit (about 103%) more effective at anisotropic filtering than the GeForce GTX 560. (explain)

GeForce GTX 295		92160 Mtexels/sec
GeForce GTX 560		45360 Mtexels/sec
	Difference: 46800 (103%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 295 is a better choice, and very much so. (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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
