GeForce GTX 295 vs GeForce GTX 650 Ti

Intro

Compare those specifications to the GeForce GTX 650 Ti, which makes use of a 28 nm design. nVidia has clocked the core speed at 928 MHz. The GDDR5 RAM works at a speed of 1350 MHz on this particular model. It features 768 SPUs along with 64 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 Ti		110 Watts
GeForce GTX 295		289 Watts
	Difference: 179 Watts (163%)

Memory Bandwidth

In theory, the GeForce GTX 295 should be 159% quicker than the GeForce GTX 650 Ti overall, because of its higher bandwidth. (explain)

GeForce GTX 295		223776 MB/sec
GeForce GTX 650 Ti		86400 MB/sec
	Difference: 137376 (159%)

Texel Rate

The GeForce GTX 295 will be much (more or less 55%) faster with regards to anisotropic filtering than the GeForce GTX 650 Ti. (explain)

GeForce GTX 295		92160 Mtexels/sec
GeForce GTX 650 Ti		59392 Mtexels/sec
	Difference: 32768 (55%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 295 is a better choice, by a large margin. (explain)

GeForce GTX 295		32256 Mpixels/sec
GeForce GTX 650 Ti		14848 Mpixels/sec
	Difference: 17408 (117%)

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
