GeForce GTX 275 vs GeForce GTX 560

Intro

The GeForce GTX 275 features a core clock frequency of 633 MHz and a GDDR3 memory speed of 1134 MHz. It also features a 448-bit memory bus, and makes use of a 55 nm design. It is made up of 240 SPUs, 80 Texture Address Units, and 28 Raster Operation Units.

Compare those specifications to the GeForce GTX 560, which uses a 40 nm design. nVidia has set the core speed at 810 MHz. The GDDR5 memory is set to run at a frequency of 1001 MHz on this specific model. It features 336 SPUs as well as 56 TAUs and 32 ROPs.

GeForce GTX 275 127008 MB/sec
Difference: 1120 (1%)

Texel Rate

The GeForce GTX 275 will be a bit (approximately 12%) more effective at AF than the GeForce GTX 560. (explain)

GeForce GTX 275 50640 Mtexels/sec
GeForce GTX 560 45360 Mtexels/sec
Difference: 5280 (12%)

Pixel Rate

The GeForce GTX 560 is a lot (more or less 46%) better at AA than the GeForce GTX 275, and also should be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 560 25920 Mpixels/sec
GeForce GTX 275 17724 Mpixels/sec
Difference: 8196 (46%)

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.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
