GeForce GTX 260 Core 216 vs GeForce GTX 275

Intro

Compare those specs to the GeForce GTX 275, which uses a 55 nm design. nVidia has clocked the core speed at 633 MHz. The GDDR3 RAM runs at a frequency of 1134 MHz on this card. It features 240 SPUs as well as 80 TAUs and 28 ROPs.

GeForce GTX 260 Core 216		111888 MB/sec
	Difference: 15120 (14%)

Texel Rate

The GeForce GTX 275 will be a lot (about 22%) better at anisotropic filtering than the GeForce GTX 260 Core 216. (explain)

GeForce GTX 275		50640 Mtexels/sec
GeForce GTX 260 Core 216		41472 Mtexels/sec
	Difference: 9168 (22%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 275 is a better choice, though only just barely. (explain)

GeForce GTX 275		17724 Mpixels/sec
GeForce GTX 260 Core 216		16128 Mpixels/sec
	Difference: 1596 (10%)

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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
