GeForce GTX 285 2GB vs GeForce GTX 560 Ti
Intro
The GeForce GTX 285 2GB has core clock speeds of 648 MHz on the GPU, and 1242 MHz on the 2048 MB of GDDR3 RAM. It features 240 SPUs as well as 80 Texture Address Units and 32 Rasterization Operator Units.Compare that to the GeForce GTX 560 Ti, which comes with a core clock frequency of 822 MHz and a GDDR5 memory frequency of 1002 MHz. It also uses a 256-bit memory bus, and uses a 40 nm design. It is made up of 384 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units of the card 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 processed in one second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.

Comments
One Response to “GeForce GTX 285 2GB vs GeForce GTX 560 Ti”I find it interesting that the older 285 still fares pretty well against newer cards. It seems that if you are not going for ultra high res, the 285 is still capable. I wonder where you start to draw the line... 1920 x 1080? 2560 x 1440?
Right now 1920 x 1080 seems to be good with my 285. Perhaps there will be a steep dropoff above that.
