GeForce GTX 285 1GB vs GeForce GTX 660

Intro

The GeForce GTX 285 1GB comes with core speeds of 648 MHz on the GPU, and 1242 MHz on the 1024 MB of GDDR3 RAM. It features 240 SPUs as well as 80 TAUs and 32 Rasterization Operator Units.

Compare those specs to the GeForce GTX 660, which makes use of a 28 nm design. nVidia has clocked the core speed at 980 MHz. The GDDR5 RAM runs at a speed of 1502 MHz on this particular model. It features 960 SPUs along with 80 Texture Address Units and 24 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 660 140 Watts
GeForce GTX 285 1GB 204 Watts
Difference: 64 Watts (46%)

Memory Bandwidth

In theory, the GeForce GTX 285 1GB should perform a bit faster than the GeForce GTX 660 overall. (explain)

GeForce GTX 285 1GB 158976 MB/sec
GeForce GTX 660 144192 MB/sec
Difference: 14784 (10%)

Texel Rate

The GeForce GTX 660 should be much (approximately 51%) faster with regards to anisotropic filtering than the GeForce GTX 285 1GB. (explain)

GeForce GTX 660 78400 Mtexels/sec
GeForce GTX 285 1GB 51840 Mtexels/sec
Difference: 26560 (51%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 660 is a better choice, not by a very large margin though. (explain)

GeForce GTX 660 23520 Mpixels/sec
GeForce GTX 285 1GB 20736 Mpixels/sec
Difference: 2784 (13%)

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: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines 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 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.

If you're going for a 285 get the 2GB version... I would personally recommend an r9 280x though.
