GeForce GTX 295 vs GeForce GTX 660 Ti

Intro

The GeForce GTX 295 uses a 55 nm design. nVidia has set the core speed at 576 MHz. The GDDR3 memory is set to run at a speed of 999 MHz on this specific model. It features 240 SPUs along with 80 Texture Address Units and 28 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 660 Ti, which comes with GPU core speed of 915 MHz, and 2048 MB of GDDR5 RAM set to run at 1500 MHz through a 192-bit bus. It also is comprised of 1344 SPUs, 112 Texture Address Units, and 24 Raster Operation Units.

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

Texel Rate

The GeForce GTX 660 Ti should be just a bit (approximately 11%) better at AF 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 a lot (about 47%) faster with regards to FSAA than the GeForce GTX 660 Ti, and should be able to handle higher resolutions without slowing down too much. (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.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video 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 write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
