GeForce GTX 285 2GB vs GeForce GTX 560 Ti

Intro

The GeForce GTX 285 2GB features a GPU core speed of 648 MHz, and the 2048 MB of GDDR3 memory runs at 1242 MHz through a 512-bit bus. It also features 240 SPUs, 80 Texture Address Units, and 32 ROPs.

Compare those specs to the GeForce GTX 560 Ti, which has GPU clock speed of 822 MHz, and 1024 MB of GDDR5 RAM set to run at 1002 MHz through a 256-bit bus. It also is comprised of 384 Stream Processors, 64 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB 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 its memory speed. In the case of DDR type 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 AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video 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 number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant 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 max fill rate.

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.
