GeForce GTX 285 2GB vs GeForce GTX 560 Ti

Intro

The GeForce GTX 285 2GB uses a 55 nm design. nVidia has set the core speed at 648 MHz. The GDDR3 RAM works at a speed of 1242 MHz on this specific card. It features 240 SPUs along with 80 Texture Address Units and 32 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 560 Ti, which comes with clock speeds of 822 MHz on the GPU, and 1002 MHz on the 1024 MB of GDDR5 RAM. It features 384 SPUs as well as 64 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 560 Ti 170 Watts
GeForce GTX 285 2GB 204 Watts
Difference: 34 Watts (20%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 285 2GB is 24% faster than the GeForce GTX 560 Ti overall, because of its higher data rate. (explain)

GeForce GTX 285 2GB 158976 MB/sec
GeForce GTX 560 Ti 128256 MB/sec
Difference: 30720 (24%)

Texel Rate

The GeForce GTX 560 Ti should be just a bit (approximately 1%) more effective at texture filtering than the GeForce GTX 285 2GB. (explain)

GeForce GTX 560 Ti 52608 Mtexels/sec
GeForce GTX 285 2GB 51840 Mtexels/sec
Difference: 768 (1%)

Pixel Rate

The GeForce GTX 560 Ti should be a lot (approximately 27%) more effective at full screen anti-aliasing than the GeForce GTX 285 2GB, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 560 Ti 26304 Mpixels/sec
GeForce GTX 285 2GB 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.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 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 number of texture map elements (texels) that can be processed per 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the 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.
