GeForce GTX 295 vs GeForce GTX 650 Ti

Intro

Compare those specs to the GeForce GTX 650 Ti, which has GPU clock speed of 928 MHz, and 1024 MB of GDDR5 memory running at 1350 MHz through a 128-bit bus. It also features 768 Stream Processors, 64 Texture Address Units, and 16 ROPs.

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

Memory Bandwidth

The GeForce GTX 295 should in theory be quite a bit faster than the GeForce GTX 650 Ti overall. (explain)

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

Texel Rate

The GeForce GTX 295 is quite a bit (more or less 55%) more effective at AF 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 lots of anti-aliasing is important to you, then the GeForce GTX 295 is the winner, by far. (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: Bandwidth is the max amount of data (in units of MB per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If it uses 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
