GeForce GTX 260 Core 216 vs GeForce GTX 295

Intro

Compare those specifications to the GeForce GTX 295, which features a core clock frequency of 576 MHz and a GDDR3 memory speed of 999 MHz. It also uses a 448-bit memory bus, and makes use of a 55 nm design. It is comprised of 240 SPUs, 80 TAUs, and 28 Raster Operation Units.

In theory, the GeForce GTX 295 will be 100% quicker than the GeForce GTX 260 Core 216 in general, due to its greater data rate. (explain)

GeForce GTX 295		223776 MB/sec
GeForce GTX 260 Core 216		111888 MB/sec
	Difference: 111888 (100%)

Texel Rate

The GeForce GTX 295 should be much (about 122%) more effective at anisotropic filtering than the GeForce GTX 260 Core 216. (explain)

GeForce GTX 295		92160 Mtexels/sec
GeForce GTX 260 Core 216		41472 Mtexels/sec
	Difference: 50688 (122%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 295 is superior to the GeForce GTX 260 Core 216, by far. (explain)

GeForce GTX 295		32256 Mpixels/sec
GeForce GTX 260 Core 216		16128 Mpixels/sec
	Difference: 16128 (100%)

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 (counted in megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
