GeForce GTX 295 vs GeForce GTX 660 Ti

Intro

The GeForce GTX 295 uses a 55 nm design. nVidia has clocked the core frequency at 576 MHz. The GDDR3 RAM works at a frequency of 999 MHz on this card. It features 240 SPUs as well as 80 TAUs and 28 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 660 Ti, which has a core clock speed of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also makes use of a 192-bit bus, and uses a 28 nm design. It is made up 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

Theoretically speaking, the GeForce GTX 295 will be 55% quicker than the GeForce GTX 660 Ti in general, due to its greater data rate. (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 bit (more or less 11%) faster with regards to 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

If using a high resolution is important to you, then the GeForce GTX 295 is the winner, by a large margin. (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 data (in units of megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
