GeForce GTX 295 vs GeForce GTX 660 Ti

Intro

Compare that to the GeForce GTX 660 Ti, which comes with a core clock frequency of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also features a 192-bit bus, and makes use of a 28 nm design. It is comprised of 1344 SPUs, 112 Texture Address Units, and 24 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 660 Ti		150 Watts
GeForce GTX 295		289 Watts
	Difference: 139 Watts (93%)

Memory Bandwidth

The GeForce GTX 295 should in theory perform a lot faster than the GeForce GTX 660 Ti overall. (explain)

GeForce GTX 295		223776 MB/sec
GeForce GTX 660 Ti		144000 MB/sec
	Difference: 79776 (55%)

Texel Rate

The GeForce GTX 660 Ti should be a little bit (more or less 11%) better at texture filtering than the GeForce GTX 295. (explain)

GeForce GTX 660 Ti		102480 Mtexels/sec
GeForce GTX 295		92160 Mtexels/sec
	Difference: 10320 (11%)

Pixel Rate

The GeForce GTX 295 should be quite a bit (about 47%) more effective at full screen anti-aliasing than the GeForce GTX 660 Ti, and also should be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 295		32256 Mpixels/sec
GeForce GTX 660 Ti		21960 Mpixels/sec
	Difference: 10296 (47%)

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 (counted in megabytes per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
