GeForce GTX 295 vs GeForce GTX 560

Intro

Compare those specifications to the GeForce GTX 560, which features GPU core speed of 810 MHz, and 1024 MB of GDDR5 memory running at 1001 MHz through a 256-bit bus. It also features 336 SPUs, 56 TAUs, and 32 ROPs.

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 better than 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 (more or less 103%) faster with regards to texture 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 running with a high resolution is important to you, then the GeForce GTX 295 is superior to the GeForce GTX 560, 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 (measured in MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

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