GeForce GTX 260 Core 216 vs GeForce GTX 550 Ti

Intro

Compare all of that to the GeForce GTX 550 Ti, which features GPU clock speed of 900 MHz, and 1024 MB of GDDR5 memory running at 1026 MHz through a 192-bit bus. It also is comprised of 192 Stream Processors, 32 TAUs, and 24 Raster Operation Units.

GeForce GTX 260 Core 216		111888 MB/sec
GeForce GTX 550 Ti		98496 MB/sec
	Difference: 13392 (14%)

Texel Rate

The GeForce GTX 260 Core 216 will be quite a bit (approximately 44%) more effective at AF than the GeForce GTX 550 Ti. (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
GeForce GTX 550 Ti		28800 Mtexels/sec
	Difference: 12672 (44%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 550 Ti is superior to the GeForce GTX 260 Core 216, by a large margin. (explain)

GeForce GTX 550 Ti		21600 Mpixels/sec
GeForce GTX 260 Core 216		16128 Mpixels/sec
	Difference: 5472 (34%)

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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling 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 card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units 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 fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
