GeForce GTX 285 2GB vs GeForce GTX 560 Ti
Intro
The GeForce GTX 285 2GB has a clock speed of 648 MHz and a GDDR3 memory frequency of 1242 MHz. It also uses a 512-bit bus, and uses a 55 nm design. It is made up of 240 SPUs, 80 TAUs, and 32 ROPs.Compare those specs to the GeForce GTX 560 Ti, which comes with core speeds of 822 MHz on the GPU, and 1002 MHz on the 1024 MB of GDDR5 memory. It features 384 SPUs along with 64 TAUs and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max 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.
