GeForce GTX 285 1GB vs GeForce GTX 560 Ti

Intro

Compare those specs to the GeForce GTX 560 Ti, which makes use of a 40 nm design. nVidia has clocked the core frequency at 822 MHz. The GDDR5 RAM works at a frequency of 1002 MHz on this model. It features 384 SPUs along with 64 Texture Address Units and 32 Rasterization Operator Units.

GeForce GTX 285 1GB		51840 Mtexels/sec
	Difference: 768 (1%)

Pixel Rate

The GeForce GTX 560 Ti should be much (about 27%) more effective at FSAA than the GeForce GTX 285 1GB, and also able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
GeForce GTX 285 1GB		20736 Mpixels/sec
	Difference: 5568 (27%)

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 (in units of megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units by the core clock 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 processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
