GeForce GTX 260 Core 216 vs GeForce GTX 560 Ti 448

Intro

Compare all that to the GeForce GTX 560 Ti 448, which uses a 40 nm design. nVidia has clocked the core frequency at 732 MHz. The GDDR5 RAM works at a speed of 900 MHz on this specific card. It features 448 SPUs as well as 56 Texture Address Units and 40 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 260 Core 216		202 Watts
GeForce GTX 560 Ti 448		210 Watts
	Difference: 8 Watts (4%)

Memory Bandwidth

In theory, the GeForce GTX 560 Ti 448 should be 29% faster than the GeForce GTX 260 Core 216 in general, due to its greater data rate. (explain)

GeForce GTX 560 Ti 448		144000 MB/sec
GeForce GTX 260 Core 216		111888 MB/sec
	Difference: 32112 (29%)

Texel Rate

The GeForce GTX 260 Core 216 will be a little bit (approximately 1%) more effective at texture filtering than the GeForce GTX 560 Ti 448. (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
GeForce GTX 560 Ti 448		40992 Mtexels/sec
	Difference: 480 (1%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 560 Ti 448 is a better choice, and very much so. (explain)

GeForce GTX 560 Ti 448		29280 Mpixels/sec
GeForce GTX 260 Core 216		16128 Mpixels/sec
	Difference: 13152 (82%)

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 max amount of information (measured in MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 is worked out by multiplying the total amount of texture units 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 a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core 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 rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
